Livestock use of water in/from treatment area. There are no restrictions on livestock consumption of 

water from the treatment area. 

Precautions for potable water intakes. DO NOT apply Imazapyr 2SL directly to water within 11, mile 

upstream of an active potable water intake in flowing water (i.e., river, stream, etc.) or within 11, miles of an 

active potable water intake in a standing body of water such as a lake, pond or reservoir. To make 

aquatic applications around and within 11, mile of active potable water intakes, the intake must be turned 

off during application and for a minimum of 48 hours after the application. These aquatic applications 

may be made only in the cases where there are alternative water sources or holding ponds that would 

permit turning off of an active potable water intake for a minimum period of 48 hours after the 

applications. 

NOTE: Existing potable water intakes that are no longer in use, such as those replaced by connections 

to wells or a municipal water system, are not considered to be active potable water intakes. This 

restriction does not apply to intermittent, inadvertent overspray or water in terrestrial use sites. 

Quiescent or Slow-moving Waters. In lakes and reservoirs, DO NOT apply Imazapyr 2SL within one 

(1) mile of an active irrigation water intake during the irrigation season. Applications less than one (1) 

mile from an irrigation water intake may be made during the off-season, provided that the irrigation intake 

will remain inactive for a minimum of 120 days after application or until Imazapyr 2SL residue levels are 

determined by laboratory analysis or other appropriate means of analysis to be 1.0 ppb or less. 

PRODUCT INFORMATION 

Imazapyr 2SL is an aqueous solution to be mixed with water and a surfactant and applied as a spray 

solution to control undesirable vegetation growing within forestry sites and specified aquatic, industrial 

4 

8
( 

non-cropland sites, and railroad, utility, and highway rights-of-way, and non-agricultural fence rows. 

Aquatic sites consist of standing and flowing water, wetland, and riparian areas. Industrial non-cropland 

sites include utility plant sites, petroleum tank farms, pumping installations, non-agricultural fence rows, 

storage areas, and non-irrigation ditchbanks. Imazapyr 2SL may also be used for the establishment and 

maintenance of wildlife openings, for the release of unimproved Bermudagrass and Bahiagrass, for 

bareground weed control, and for use under certain paved surfaces. 

Imazapyr 2SL may be applied on forestry sites that contain areas of temporary surface water caused by 

the collection of water between planting beds, in equipment ruts, or in other depressions created by forest 

management activities, except in the states of California and New York. It is permissible to treat drainage 

ditches, intermittent drainage, intermittently flooded low lying sites, seasonally dry flood plains, and 

transitional areas between upland and lowland sites when no water is present except in the states of 

California and New York. Only the edge of drainage ditches can be treated for drainage ditches that 

contain water. It is also permissible to treat marshes, swamps, and bogs after water has receded, as well 

as seasonally dry flood deltas, except in the states of California and New York. 

Herbicidal Activity. Imazapyr 2SL will control most annual and perennial grasses and broad leaf weeds 

in addition to many brush and vine species with some residual control of undesirable species that 

germinate above the waterline. Imazapyr 2SL is readily absorbed through emergent leaves and stems 

and is translocated rapidly throughout the plant with accumulation in the meristematic regions. For 

maximum activity, weeds should be growing vigorously at the time of application, and the spray solution 

should include a surfactant (see ADJUVANTS section for specific directions). Treated plants stop 

growing soon after spray application. 

Chlorosis appears first in the newest leaves, and necrosis spreads from this point. In perennials, the 

herbicide is translocated into, and kills, underground or submerged storage organs, which prevents 

regrowth. Chlorosis and tissue necrosis may not be apparent in some plant species until 2 or more 

weeks after application. Complete kill of plants may not occur for several weeks. Applications of 

Imazapyr 2SL are rainfast one hour after treatment. 

Application Methods. Imazapyr 2SL may be selectively applied by using low-volume directed 

application techniques or may be broadcast applied by using ground equipment, watercraft, or aircraft 

(aerial applications to aquatic sites must be made by helicopter). In addition, Imazapyr 2SL may also be 

applied using cut stump, cut stem, and frill and girdle treatment techniques within non-cropland, and 

aquatic sites (see AERIAL APPLICATIONS and GROUND APPLICATIONS sections for additional 

details). 

PRECAUTIONS FOR AVOIDING INJURY TO NON-TARGET PLANTS 

Untreated desirable plants can be affected by root uptake of Imazapyr 2SL from treated soil. Injury or 

loss of desirable plants may result if Imazapyr 2SL is applied on or near desirable plants, on areas where 

their roots extend, or in locations where the treated soil may be washed or moved into contact with their 

roots. When making applications along shorelines where desirable plants may be present, caution should 

be exercised to avoid spray contact with their foliage or spray application to the soil in which they are 

rooted. Shoreline plants that have roots which extend into the water in an area where Imazapyr 2SL has 

been applied generally will not be adversely affected by uptake of the herbicide from the water. 

If treated vegetation is to be removed from the application site, DO NOT use the vegetative matter as 

mulch or compost on or around desirable species. 

MANAGING OFF-TARGET MOVEMENT 

Aerial Applications 

• Applicators are required to use a coarse or coarser droplet size (ASABE S572) or, if specifically using 

a spinning atomizer nozzle applicators are required to use a volume mean diameter (VMD) of 385 

microns or greater for release heights below 10 feet. Applicators are required to use a very coarse or 

coarser droplet size or, if specifically using a spinning atomizer nozzle, applicators are required to use 

5 

9
a VMD of 475 microns or greater for release heights above 10 feet. Applicators must consider the 

effects of nozzle orientation and fiight speed when determining droplet size. 

• Applicators are required to use upwind swath displacement. 

• The boom length must not exceed 60% of the wingspan or 90% of the rotor blade diameter to reduce 

spray drift. 

• Applications with wind speeds less than 3 mph and with wind speeds greater than 10 mph are 

prohibited. 

• Applications into temperature inversions are prohibited. 

Ground Boom Applications 

• Applicators are required to use a nozzle height below 4 feet above ground or plant canopy and 

coarse or coarser droplet size (ASABE S572) or, if specifically using a spinning atomizer nozzle, 

applicators are required to use a volume mean diameter (VMD) of 385 microns or greater. 

• Applications with wind speeds greater than 10mph are prohibited. 

• Applications into temperature inversions are prohibited. 

Wind Erosion 

Avoid treating powdery, dry or light sandy soils when conditions are favorable for wind erosion. Under 

these conditions, the soil surface should first be settled by rainfall or irrigation. 

ADJUVANTS 

Postemergence applications of Imazapyr 2SL require the addition of a spray adjuvant. When making 

aquatic applications, only spray adjuvants that are approved or appropriate for aquatic use must be 

utilized. 

Nonionic Surfactants. Use a non ionic surfactant (NIS) at the rate of 0.25% volume/volume (v/v) or 

higher (see manufacturer's label) of the spray solution (0.25% v/v is equivalent to 1 quart in 100 gallons). 

For best results, select a nonionic surfactant with an HLB (hydrophilic to lipophilic balance) ratio between 

12 and 17 with at least 70% surfactant in the formulated product (alcohols, fatty acids, oils, ethylene 

glycol or diethylene glycol should not be considered as surfactants to meet the above requirements. 

Methylated Seed Oils or Vegetable Oil Concentrates. Instead of a surfactant, a methylated seed oil 

(MSO) or vegetable-based seed oil concentrate may be used at the rate of 1.5 to 2 pints per acre. When 

using spray volumes greater than 30 gallons per acre, methylated seed oil or vegetable-based seed oil 

concentrates should be mixed at a rate of 1 % of the total spray volume, or alternatively use a nonionic 

surfactant as described above. Research indicates that these oils may aid in Imazapyr 2SL deposition 

and uptake by plants under moisture or temperature stress. 

Silicone-based Surfactants. See manufacturer's label for specific rate directions. Silicone-based 

surfactants may reduce the surface tension of the spray droplet allowing greater spreading on the leaf 

surface as compared to conventional non ionic surfactants. However, some silicone-based surfactants 

may dry too quickly, limiting herbicide uptake. 

Fertilizer/Surfactant Blends: Nitrogen-based liquid fertilizers, such as 28%N, 32%N, 10-34-0 or 

ammonium sulfate, may be added at the rate of 2 to 3 pints per acre in combination with the labeled rate 

of nonionic surfactant, methylated seed oil or vegetable/seed oil concentrate. Do not use fertilizers in a 

tank mix without a non ionic surfactant, methylated seed oil or vegetable/seed oil concentrate. 

Invert Emulsions. Imazapyr 2SL can be applied as an invert emulsion. The spray solution results in an 

invert (water-in-oil) spray emulsion designed to minimize spray drift and spray runoff, resulting in more 

herbicide on the target foliage. The spray emulsion may be formed in a single tank (batch mixing) or 

injected (in-line mixing). Consult the invert chemical label for proper mixing directions. 

6 

10
Other. An antifoaming agent, spray pattern indicator, or drift-reducing agent may be applied at the 

product labeled rate if necessary or desired. 

TANK MIXES 

Imazapyr 2SL may be tank mixed with other herbicides. 

Consult manufacturer's labels for specific rate restrictions and weeds controlled. Always follow the more 

restrictive label restrictions and precautions for all products used when making an application involving 

tank mixes. 

AERIAL APPLICATIONS 

All precautions should be taken to minimize or eliminate spray drift. Also see "MANAGING OFF-TARGET 

MOVEMENT" on the label. Both fixed-wing aircraft and helicopters can be used to apply Imazapyr 2SL 

on non-cropland sites, but only helicopters can be used for aquatic applications. DO NOT make 

applications by fixed-wing aircraft or helicopter unless appropriate buffer zones can be maintained to 

prevent spray drift out of the target area, or when treating open tracts of land, spray drift as a result of 

fixed-wing aircraft application can be tolerated. Aerial equipment designed to minimize spray drift, such 

as helicopter equipped with a MicrofoilTM boom, Thru-ValveTM boom, or raindrop nozzles, must be used 

and calibrated. Except when applying with a MicrofojITM boom, a drift control agent may be added at the 

specified label rate. Do not side trim with Imazapyr 2SL unless death of treated tree can be tolerated. 

Uniformly apply the specified amount of Imazapyr 2SL in 2 to 30 gallons of water per acre. A foamreducing agent may be added at the labeled rate, if needed. 

IMPORTANT: Thoroughly clean application equipment, including landing gear, immediately after use of 

this product. Prolonged exposure of this product to uncoated steel (except stainless steel) surfaces may 

result in corrosion and failure of the exposed part. The maintenance of an organic coating (paint) may 

prevent corrosion. 

FOLIAR APPLICA TIONS 

Low-Volume Foliar Application 

GROUND APPLICATIONS 

Use equipment calibrated to deliver 5 to 20 gallons of spray solution per acre. To prepare the spray 

solution, thoroughly mix in water 0.5% to 5% Imazapyr 2SL plus surfactant (see the ADJUVANTS 

section of this label for specific directions). A foam-reducing agent may be applied at the specified label 

rate, if needed. For control of difficult species (see Aquatic Weeds Controlled section and the 

Terrestrial Weeds Controlled by Imazapyr 2SL section for relative susceptibility of weed species), use 

the higher concentrations of herbicide and/or spray volumes, but DO NOT apply more than 6 pints of 

Imazapyr 2SL per acre in aquatic and non-cropland sites. Do not excessively wet foliage. See Spray 

Solution Mixing Guide for Low-Volume Foliar Applications for specified volumes of Imazapyr 2SL 

and water. 

For low-volume foliar application, select proper nozzles to avoid over-application. Proper application is 

critical to ensure desirable results. Best results are achieved when the spray covers the crown and 

approximately 70 percent of the plant. The use of an even, flat-fan tip with a spray angle of 40 degrees or 

less will aid in proper deposition. 

Recommended tip sizes include 4004E or 1504E. For a straight-stream and cone pattern, adjustable 

cone nozzles, such as 5500 X3 or 5500 X4, may be used. Attaching a rollover valve onto a Spraying 

Systems Model 30 gunjet or other similar spray gun allows for the use of both flat-fan and cone tips on 

the same gun. 

7 

11
( ( 

Moisten, but DO NOT drench target vegetation causing spray solution to run off. 

Low-volume Foliar Application with Backpacks 

For low-growing species, spray down on the crown, covering crown, and penetrating approximately 70% 

of the plant. 

For target species 4 to 8 feet tall, swipe the sides of target vegetation by directing spray to at least 2 sides 

of the plant in smooth vertical motions from the crown to the bottom. Make sure to cover the crown 

whenever possible. 

For target species over 8 feet tall, lace sides of the target vegetation by directing spray to at least 2 sides 

of the target in smooth zigzag motions from crown to bottom. 

Low-volume Foliar Application with Hydraulic Handgun Application Equipment 

Use the same technique as described above for Low-volume Foliar Application with Backpacks. 

For broadcast applications, simulate a gentle rain near the top of target vegetation allowing spray to 

contact the crown and penetrate the target foliage without falling to the understory. Herbicide spray 

solution that contacts the understory may result in severe injury or death of plants in the understory.

High Volume Foliar Application 

For optimum performance when spraying medium-density to high-density vegetation, use equipment 

calibrated to deliver up to 100 gallons of spray solution per acre (GPA). Spray solutions exceeding 100 

GPA may result in excessive spray runoff, causing increased ground cover injury, and injury to desirable 

species. To prepare the spray solution, thoroughly mix Imazapyr 2SL in water and add a surfactant (see 

ADJUVANTS section for specific directions and rates of surfactants). A foam-reducing agent may be 

added at the labeled rate, if needed. For control of difficult species (see Aquatic Weeds Controlled 

chart and the Terrestrial Weeds Controlled by Imazapyr 2SL section for relative susceptibility of weed 

species), use the higher concentrations of herbicide and/or spray volumes, but DO NOT apply more than 

6 pints of Imazapyr 2SL per acre in aquatic and non-cropland sites. Uniformly cover the foliage of the 

vegetation to be controlled, but DO NOT apply to runoff. Do not excessively wet foliage. 

Side Trimming 

DO NOT side trim with Imazapyr 2SL unless severe injury or death of the treated tree can be tolerated. 

Imazapyr 2SL is readily translocated and can result in death of the entire tree.

CUT-SURFACE TREATMENTS 

Imazapyr 2SL may be used to control undesirable woody vegetation by applying the Imazapyr 2SL 

solution to the cambium area of freshly cut stump surfaces or to fresh cuts on the stem of the target 

woody vegetation. Applications can be made at any time of the year except during periods of heavy sap 

flow in the spring. DO NOT overapply solution causing runoff from the cut surface. 

Injury may occur to desirable woody plants if the shoots extend from the same root system or their root 

systems are grafted to those of the treated tree. 

Cut-surface Applications With Dilute and Concentrate Solutions 

Imazapyr 2 SL may be mixed as either a concentrated or dilute solution. The dilute solution may be used 

for applications to the cut surface of the stump or to cuts on the stem of the target woody vegetation. 

Concentrated solutions may be used for applications to cuts on the stem. Use of the concentrated 

solution permits application to fewer cuts on the stem, especially for large-diameter trees. Follow the 

application instructions to determine proper application techniques for each type of solution. 

• To prepare a dilute solution, mix 8 to 12 fluid ounces of Imazapyr 2SL with 1 gallon of water. The 

use of a surfactant or penetrating agent may improve uptake through partially callused cambiums. 

• To prepare concentrated solution, mix 2 quarts of Imazapyr 2SL with no more than 1 quart of water. 

Cut-Stump Treatments 

• Dilute Solutions. Spray or brush the solution onto the cambium area of the freshly cut stump 

surface. Ensure that the solution thoroughly wets the entire cambium area (the wood next to the bark 

of the stump). 

Cut-Stem (injection, hack and squirt) Treatments 

• Dilute Solutions. Using standard injection equipment, apply 1 milliliter of solution at each injection 

site around the tree with no more than 1-inch intervals between cut edges. Ensure that the injector 

completely penetrates the bark at each injection site. 

• Concentrate Solutions. Using standard injection equipment, apply 1 milliliter of solution at each 

injection site. Make at least 1 injection cut for every 3 inches of Diameter at Breast Height (DBH) on 

the target tree. For example, a 3-inch DBH tree will receive 1 injection cut, and a 6-inch DBH tree will 

receive 2 injection cuts. On trees requiring more than 1 injection site, place the injection cuts at 

approximately equal intervals around the tree. 

Frill or Girdle Treatments 

• Using a hatchet, machete, or chainsaw, make cuts through the bark and completely around the tree 

to expose the cambium. The cut should angle downward extending into the cambium enough to 

expose at least 2 growth rings. Using a spray applicator or brush, apply a 25% to 100% solution of 

Imazapyr 2SL into each cut until thoroughly wet. Avoid applying so much herbicide that runoff to the 

ground or water occurs. 

NON-CROPLAND USES 

Applications may be made for the control of undesirable vegetation growing within industrial non-cropland 

sites. Industrial non-cropland sites include utility plant sites, petroleum tank farms, pumping installations, 

non-agricultural fence rows, storage areas, and non-irrigation ditchbanks. Imazapyr 2SL may also be 

used for the establishment and maintenance of wildlife openings, for the release of unimproved 

Bermudagrass and Bahiagrass, for bareground weed control, and for use under certain paved surfaces. 

Applications to non-cropland areas that are not applicable to treatment of commercial timber or other 

plants being grown for sale or other commercial use, or for commercial seed production, or for research 

purposes.

Imazapyr 2SL may be used on unimproved Bermudagrass and Bahiagrass turf such as roadsides, utility 

rights-of-way, and other non-cropland industrial sites. The application of Imazapyr 2SL on established 

common and coastal Bermudagrass and Bahiagrass provides control of labeled broad leaf and grass 

weeds. Competition from these weeds is eliminated, releasing the Bermudagrass and Bahiagrass. 

Treatment of Bermudagrass with Imazapyr 2SL results in a compacted growth habit and seed-head 

inhibition. 

Uniformly apply with properly calibrated ground equipment using at least 10 gallons of water per acre. 

IMPORTANT: Temporary yellowing of grass may occur when treatment is made after growth 

commences. DO NOT add surfactant in excess of the specified rate (1 oz per 25 gallons of spray 

solution). DO NOT APPLY to grass during its first growing season. DO NOT APPLY to grass that is 

under stress from drought, disease, insects, or other causes.

DOSAGE RATES AND TIMING 

Bermudagrass. Apply Imazapyr 2SL at 6 to 12 ozs per acre when the Bermudagrass is dormant. Apply 

Imazapyr 2SL at 6 to 8 ozs per acre after Bermudagrass has reached full green-up. Applications made 

during green-up will delay green-up. Include a surfactant in the spray solution (see IMPORTANT note 

above). 

For additional preemergence control of annual grasses and small-seeded broad leaf weeds, add 

Pendulum® Aquacap TM herbicide at the rate of 3.1 to 6.3 pints per acre. Consult the Pendulum 

Aquacap label for weeds controlled and for other use directions and precautions. 

For control of Johnsongrass in Bermudagrass turf, apply Imazapyr 2SL at 8 ozs per acre, plus 

Roundup® herbicide at 12 ozs per acre, plus surfactant. For additional control of broadleaves and vines, 

Garlon® 3A may be added to the above mix at the rate of 1 to 2 pints per acre. Observe all precautions 

and restrictions on the Garlon® 3A and Roundup® labels. 

Bahiagrass. Apply Imazapyr 2SL at 4 to 8 ozs per acre when the Bahiagrass is dormant or after the 

grass has initiated green-up but has not exceeded 25% green-up. Include a surfactant in the spray 

solution. (See ADJUVANTS section for specific directions on sUrfactants).

GRASS GROWTH AND SEED-HEAD SUPPRESSION 

Imazapyr 2SL may be used to suppress growth and seed-head development of certain turfgrass in 

unimproved areas. When Imazapyr 2SL is applied to desirable turf, it may result in temporary turf 

damage and/or discoloration. Effects to the desirable turf may vary with environmental conditions. For 

optimum performance, application should be made prior to culm elongation. Applications may be made 

before or after mowing. If applied prior to mowing, allow at least 3 days of active growth before mowing. 

If applied following a mowing, allow sufficient time for the grasses to recover before applying this product 

or injury may be amplified. 

DO NOT APPLY to turf under stress (drought, cold, insect damaged, etc.) or severe injury or death may 

occur. 

Bermudagrass. Apply Imazapyr 2SL at 6 to 8 ozs per acre from early green-up to prior to seed-head 

initiation. DO NOT add a surfactant for this application. 

Cool Season Unimproved Turf. Apply Imazapyr 2SL at 2 ozs per acre plus 0.25% nonionic surfactant. 

For increased suppression, Imazapyr 2SL may be tank mixed with such products as Campaign® (24 ozs 

per acre) or Embark® (8 ozs per acre). Tank mixes may increase injury to desired turf. Consult each 

11 

15
( 

product label for specified turf species and other use directions and precautions. Tank mixes with 2, 4-0 

or products containing 2,4-0 may decrease the effectiveness of Imazapyr 2SL. 

TOTAL VEGETATION CONTROL WHERE 

BARE GROUND IS DESIRED 

Imazapyr 2SL is an effective herbicide for preemergence or postemergence control of many annual 

perennial broad leaf and grass weeds where bare ground is desired. Imazapyr 2SL is particularly 

effective on hard-to-control perennial grasses. Imazapyr 2SL herbicide at 1.5 to 6 pints per acre can be 

used alone or in a tank mix with herbicides approved for use in bare ground. The degree and duration of 

control are dependent on the rate of Imazapyr 2SL used, tank mix partner, the volume of carrier, soil 

texture, rainfall, and other conditions. 

Consult manufacturer labels for specific rates and weeds controlled. Always follow the more restrictive 

label restrictions and precautions for all products used when making an application involving tank mixes. 

Applications of Imazapyr 2SL may be made any time of the year. Use equipment calibrated to deliver 

desired gallons per acre spray volume and uniformly distribute the spray pattern over the treated area. 

Postemergence Applications. Always use a spray adjuvant (see ADJUVANTS section of this label) 

when making a postemergence application. For optimum performance on tough-to-control annual 

grasses, applications should be made at a total volume of 100 gallons per acre or less. For quicker 

burndown or brown-out of target weeds, Imazapyr 2SL may be tank mixed with Roundup herbicide. 

Tank mixes with 2, 4-0, or products containing 2, 4-0, may reduce the performance of Imazapyr 2SL. 

Always follow the more restrictive label restrictions and precautions for all products used when tank 

mixing. 

Spot Treatments. Imazapyr 2SL may be used as a follow-up treatment to control escapes or weed 

encroachment in a bareground situation. To prepare the spray solution, thoroughly mix in each gallon of 

water 0.5% to 5% Imazapyr 2SL plus an adjuvant. For increased burndown, include Roundup as a tank 

mixture. For added residual weed control, or to increase the weed spectrum, add Pendulum Aquacap 

herbicide, Overdrive® herbicide or diu ron. Always follow the more restrictive label restrictions and 

precautions for all products when tank mixing. 

FOR CONTROL OF UNDESIRABLE WEEDS 

UNDER PAVED SURFACES 

Imazapyr 2SL can be used under asphalt, pond liners and other paved areas, ONLY in industrial sites or 

where the pavement has a suitable barrier along the perimeter that prevents encroachment of roots of 

undesirable plants. 

Use Imazapyr 2SL only where the area to be treated has been prepared according to good construction 

practices. If rhizomes, stolons, tubers or other vegetative plant parts are present in the site, remove them 

be scalping with a grader blade to a depth sufficient to ensure their complete removal. 

IMPORTANT: Follow Imazapyr 2SL applications with paving as soon as possible. DO NOT apply where 

the chemical may contact the roots of desirable trees or other plants. 

Do not use this product under pavement on residential properties, such as driveways or parking lots, or 

for use in recreational areas, such as under bike or jogging paths, golf cart paths, or tennis courts, or 

where landscape plantings could be anticipated. 

Injury or death of desirable plants may result if this product is applied where roots are present or where 

roots may extend into the treated area. Roots of trees and shrubs may extend a considerable distance 

beyond the branch extremities (drip line). 

12 

16
( 

Apply to the soil surface only when final grade is established. DO NOT move soil following Imazapyr 2SL 

application. 

Apply Imazapyr 2SL in sufficient water (at least 100 gallons per acre) to ensure thorough and uniform 

wetting of the soil surface, including the shoulder areas. Add Imazapyr 2SL at a rate of 6 pints per acre 

(2.2 fluid ounces per 1000 square feet) to clean water in the spray tank during the filling operation. 

Agitate before spraying. 

If the soil is not moist prior to treatment, incorporation of Imazapyr 2SL is needed for herbicide activation. 

Incorporate Imazapyr 2SL into the soil to a depth of 4 to 6 inches using a rototiller or disc. Rainfall or 

irrigation of 1 inch will also provide uniform incorporation. DO NOT allow treated soil to wash or move 

into untreated areas. 

Spot Treatments and Crack and Crevice Treatments 

Use Imazapyr 2SL as an initial or follow-up treatment control weed escapes or weed encroachment in a 

bareground situation, including cracks and crevices in paved surfaces such as roadways, runways, and 

parking areas. 

AQUATIC WEED CONTROL 

Imazapyr 2SL may be applied for the control of floating and emergent undesirable vegetation (see the 

Aquatic Weeds Controlled and the Terrestrial Weeds Controlled by Imazapyr 2SL section) in or near 

bodies of water that may be flowing, non-flowing, or transient. Imazapyr 2SL may be applied to aquatic 

sites that include lakes, rivers, streams, ponds, seeps, drainage ditches, canals, reservoirs, swamps, 

bogs, marshes, estuaries, bays, brackish water, transitional areas between terrestrial and aquatic sites, 

riparian sites, and seasonal wet areas. See PRODUCT USE PRECAUTIONS AND RESTRICTIONS 

section of this label for precautions, restrictions, and instructions on aquatic uses. 

Read and observe the following directions if aquatic sites are present in non-crop areas and are part of 

the intended treatment area: 

Imazapyr 2SL must be applied to the emergent foliage of the target vegetation and has little-to-no activity 

on submerged aquatic vegetation. Imazapyr 2SL concentrations resulting from direct application to 

water are not expected to be of sufficient concentration nor duration to provide control of target 

vegetation. Application should be made in such a way as to maximize spray interception by the target 

vegetation while minimizing the amount of overspray that enters water. 

Imazapyr 2SL does not control plants that are completely submerged or have a majority of their foliage 

under water. 

Imazapyr 2SL should be applied with surface or helicopter application equipment in a minimum of 2 

gallons of water per acre. When applying by helicopter, follow directions under the AERIAL 

APPLICATIONS section of this label; otherwise, refer to the section on GROUND APPLICATIONS when 

using surface equipment. 

Make applications to moving bodies of water while traveling upstream to prevent concentration of this 

herbicide in water. DO NOT apply to bodies of water of portions of bodies of water where emergent 

and/or floating weeds do not exist. 

When application is to be made to target vegetation that covers a large percentage of the surface area of 

impounded water, treating the area in strips may avoid oxygen depletion due to decaying vegetation. 

Oxygen depletion may result in the suffocation of some sensitive aquatic organisms. If oxygen depletion 

is a concern, treat no more the % of the surface area of the water in a single operation and wait at least 

13 

17
( 

10 to 14 days between treatments. Begin treatment along the shore and proceed outward in bands to 

allow aquatic organisms to move into untreated areas. 

Avoid wash off of sprayed foliage by spray boat or recreational boat backwash for 1 hour after application. 

Apply Imazapyr 2SL at 2 to 6 pints per acre depending on species present and weed density. DO NOT 

exceed the maximum label rate of 6 pints per acre (1.5 Ibs ae/A) per year. Use the higher labeled rates 

for heavy weed pressure. Consult the Aquatic Weeds Controlled section and the Terrestrial Weeds 

Controlled by Imazapyr 2SL section of this label for specific rates. 

Imazapyr 2SL may be applied as a draw-down treatment in areas described above. Apply Imazapyr 

2SL to weeds after water has been drained and allow 14 days before reintroduction of water.

Terrestrial Weeds Controlled by Imazapyr 2SL herbicide 

In terrestrial sites, Imazapyr 2SL will provide preemergence or postemergence control with residual 

control of the following target vegetation species at the rates listed. Residual control refers to control of 

newly germinating seedlings in both annuals and perennials. In general, annual weeds may be controlled 

by preemergence or postemergence applications of Imazapyr 2SL. For established biennials and 

perennials, make postemergence applications of Imazapyr 2SL. 

The rates shown below pertain to broadcast applications and indicate the relative sensitivity of these 

weeds. The relative sensitivity should be referenced when preparing low-volume spray solutions (see 

Low-volume Foliar Application sections of GROUND APPLICATIONS); low-volume applications may 

provide control of the target species with less Imazapyr 2SL per acre than is shown for the broadcast 

treatments. Use Imazapyr 2SL only in accordance with the directions on this label. 

The relative sensitivity of the species listed following can also be used to determine the relative risk of 

causing nontarget plant injury if any of the species listed following are considered to be desirable within 

the area to be treated. 

Resistant Biotypes. Naturally occurring biotypes (a plant within a given species that has a slightly 

different by distinct genetic makeup from other plants of the same species) of some weeds listed on this 

label may not be effectively controlled. If naturally occurring, resistant biotypes are present in an area, 

Imazapyr 2SL should be tank mixed or applied sequentially with an appropriate registered herbicide 

having a different mode of action to ensure control.

Black Spruce (Picea mariana)' 24-32 

Red Spruce (Picea rubens) 24-32 

White Spruce (Picea g/auca)' 24 - 32 

DO NOT plant seedlings of black spruce (Plcea manana) or white spruce (Pice a g/auca) on sites that have been 

site prepared with a broadcast application of Imazapyr 2SL or into the treated zone of spot or banded site 

preparation applications for three months following treatment or injury may occur. 

2 DO NOT plant seedlings of Red Pine (Pinus res/nasa) on sites that have been site prepared with a broadcast 

application of Imazapyr 2SL or into the treated zone of spot or banded site preparation applications for six months 

following treatment or injury may occur. 

Use the specified rate of Imazapyr 2SL per acre applied as a broadcast foliar spray for long-term control 

of labeled woody plants and residual control of herbaceous weeds. Within 4 to 6 weeks of treatment, 

grasses and other herbaceous weeds will be controlled and may provide fuel to facilitate a site 

preparation burn, if desired, to control conifers or other species tolerant to the herbicide. 

For tracts to be planted with loblolly, loblolly x pitch hybrid, longleaf pine, shortleaf pine, Virginia pine and 

slash pine, Imazapyr 2SL may be applied at a rate of 64 oz per acre on areas that have little to no 

resprouting vegetation because of recent management activities such as harvesting, mechanical 

shearing, burning piling or bedding. Applications must be made after September 1. 

MIXING and APPLICATION INSTRUCTIONS for SITE PREPARATION: 

Apply the specified rate of Imazapyr 2SL per acre in 5 to 20 gallons of total spray carrier for helicopter 

applications or 5 to 40 gallons total spray carrier for mechanical or backpack ground spray applications. 

Enhanced brownout for burning and improved control of brush and grasses may be obtained by 

application of Imazapyr 2SL in 12 to 50% oil:water (volume:volume) emulsion carrier. Use methylated or 

ethylated seed oils containing at least 50% esterified seed oil by volume. Mix Imazapyr 2SL into the 

water portion of the carrier thoroughly, then add the oil and mix thoroughly again to obtain a uniform 

emulsion. Use the higher label rates of Imazapyr 2SL and higher spray volumes when controlling 

particularly dense or multi-layered canopies or hardwood stands, or difficult to control species. Make 

applications during the growing season; beginning in the spring after full leaf expansion of the target weed 

or brush has occurred and complete applications before leaf drop in the fall. 

Tank mixes may be necessary for chemical control of conifers and other species tolerant to Imazapyr 

2SL in certain cases. Observe all precautions and restrictions on the product labels. Always follow the 

most restrictive label. Combinations with other products labeled for forest site preparation may kill certain 

plants such as legumes and blackberry, which are desirable for wildlife habitat. 

DO NOT plant seedlings of black spruce (Picea mariana) or white spruce (Picea g/auca) on sites that 

have been site prepared with a broadcast application of Imazapyr 2SL or into the treated zone of spot or 

banded site preparation applications for three months following treatment or injury may occur.

HELICOPTER SPRAY EQUIPMENT 

All precautions should be taken should be taken to minimize or eliminate spray drift. Applications should 

not be made under gusty conditions. The use of controlled droplet booms and nozzle configurations is 

recommended. 

IMPORTANT: DO NOT make applications by fixed wing aircraft. Maintain adequate buffer zones. 

Thoroughly clean application and mixing equipment, including landing gear, immediately after use. 

Prolonged exposure of this product to uncoated steel (except stainless steel) surfaces may result in 

corrosion and failure of the exposed part. 

HARDWOOD SITE PREPARATION TREATMENTS 

For site preparation prior to planting hardwood species in the southeast and gulf coast states (Virginia to 

Texas), use Imazapyr 2SL at a rate of 48 oz per acre and spray before the end of July. Apply in an 

emulsion carrier with a minimum of 12% oil. DO NOT plant hardwood seedlings before January of the 

year following site preparation or injury may occur. 

DIRECTED FOLIAR APPLICATIONS 

FOR CONIFER RELEASE 

Imazapyr 2SL may be applied as a directed spray using water or oil emulsion carrier for control and 

suppression of labeled brush and weed species. Directed spray applications may be made using low 

carrier volumes (generally 10 gallons total spray per acre or less) in labeled conifer stands of all ages by 

targeting the unwanted vegetation and avoiding direct application to the conifer. Ensure that the 

maximum labeled rates per acre listed for the conifer species are not exceeded. 

Use directed foliar applications of Imazapyr 2SL for release of the following conifers from 

hardwood comDetition"

Red Spruce (Picea rubens) 12 - 24 

White Spruce (Picea glauca) 12-24 

For applications directed to the foliage of undesirable brush mix 2 to 10% Imazapyr 2SL in water. For 

brush species with thick leaf cuticles or difficult to control species use oil emulsion carrier containing 12 to 

50%, by volume, specified oil diluents. Apply the spray solution or emulsion to at least 2/3 of each 

hardwood crown using backpack sprayers or hand-held equipment. DO NOT spray to the point of runoff 

and avoid spraying the conifers for best results. For low volume foliar applications to control big leaf 

maple, use a 5% by volume Imazapyr 2SL solution or emulsion. 

Some minor conifer growth inhibition may be observed when release treatments are made during periods 

of active conifer growth. To minimize potential conifer height growth inhibition, release treatments may be 

made late in the growing season after formation of final conifer resting buds. To prevent possibility of 

23 

27
( ( 

conifer injury, DO NOT apply Imazapyr 2SL when conifers are under stress from drought, diseases, 

animal or winter injury, or other stresses reducing conifer vigor. 

Injury may occur to non-target or desirable hardwoods if they extend from the same root system as 

treated stems, or their root systems are grafted to those of the treated tree, or if their roots extend into the 

soil near treated trees. 

BAG AND BROADCAST APPLICATIONS FOR 

CONIFER RELEASE 

In Douglas-fir and Ponderosa pine stands, broadcast applications of Imazapyr 2SL up to 32 oz per acre 

are permissible when the trees are covered by bags prior to the application. The bags must prevent the 

spray mix from contacting the conifer foliage. For improved control of brush species, particularly 

evergreens, add a suitable seed oil at 5 to 12% by volume. On sites with coarse textured soils (e.g. 

decomposed granite, pumice, sandy or rocky sites) or low levels of soil organic matter (generally 5% or 

less) significant conifer growth inhibition and mortality is possible. DO NOT use this treatment on these 

types of sites if conifer growth inhibition and mortality cannot be tolerated. 

LATE ROTATION VEGETATION CONTROL 

IN WESTERN CONIFERS 

In California, the Pacific Northwest and Inland Northwest, broadcast aerial applications of Imazapyr 2SL 

up to 48 oz per acre are permissible in conifer stands that are targeted for harvesting the year following 

treatment. Use a minimum spray volume of 15 gallons per acre. For improved control of brush species, 

particularly evergreens, add a suitable seed oil at 5 to 12% by volume. Significant conifer injury or 

mortality must be expected. DO NOT use this treatment if conifer injury or mortality cannot be tolerated. 

UNDERSTORY BROADCAST APPLICATIONS 

FOR MID-ROTATION RELEASE 

Imazapyr 2SL may be applied as a broadcast application below the conifer canopy to control understory 

brush and suppress trees for labeled species. Ground spray machinery or hand held equipment may be 

used to broadcast Imazapyr 2SL in water or oil emulsion carrier below the crop tree canopy in a manner 

as to minimize spray contact by the live crown of crop trees. 

Ensure that maximum labeled rates per acre listed tor crop species below are not exceeded.

CUT STUMP TREATMENTS 

Mix 8.0 to 16.0 fluid ounces of Imazapyr 2SL in one gallon of water', s~ring oil or food/feed seed oil. 

Imazapyr 2SL may be tank mixed with Garlon® 3A, Garlon® 4, Tordon® K, Escort® or Roundup® to 

control labeled species. Spray or brush the Imazapyr 2SL solution onto the cambium area of the freshly 

cut stump surface. Ensure that the Imazapyr 2SL solution thoroughly wets the cambium area (the wood 

next to the bark) of the stump. The use of a surfactant or penetrating agent may improve uptake through 

partially callused cambiums. Applications can be made anytime during the year except during periods of 

heavy sap flow in the spring. DO NOT over apply causing puddling.

THINLINE BASAL AND STEM APPLICATIONS 

Imazapyr 2SL may be applied as a thinline basal or arcing application to the stems of susceptible 

species such as big leaf maple (Acer macrophyllum), willow (Salix spp.) and Eucalyptus (Eucalyptus spp.) 

with a stem ground line diameter of 3 inches or less. Mix 24 to 48 ounces of Imazapyr 2SL in one gallon 

of diesel oil or penetrating oil. Maintain uniform mixtures with frequent agitation. Direct a thin line of the 

spray solution to the stems beginning a few feet from the ground and descending toward the base of the 

tree making a zig-zag motion. DO NOT over apply causing puddling. 

LOW VOLUME BASAL BARK TREATMENTS 

Mix 8.0 to 12.0 fluid ounces of Imazapyr 2SL in one gallon of spring oil or food/feed seed oil. To control 

mixed brush species with up to 4 inch stem diameter at breast height, spray to wet the lower 12 to 18 

inches of the stem with the Imazapyr 2SL oil mixture (include the root collar area). DO NOT over apply 

causing dripping or puddling. Maintain uniform mixtures with frequent agitation. 

LOW VOLUME FOLIAR APPLICATIONS 

Imazapyr 2SL may be applied as a low volume foliar application. Mix 3 to 5% Imazapyr 2SL in water 

and adjuvant or in a penetrating oil. For small brush, spray down on the crown to cover approximately 

70% of the plant foliage. For larger brush ensure coverage on as much of the crown as possible and 

spray at least two sides of the plan!. Imazapyr 2SL may be tank mixed with other labeled herbicides. 

Use a tank mix of 3 to 5% Imazapyr 2SL plus 15 to 20% Garlon 4 in basal oil to control black locust, 

honey locust, hackberry, elms and other species listed on the manufacturer's labels. Use the higher rate 

of Imazapyr 2SL (5%) in areas containing sassafras, oak, hickory, cherry, and maples or in the southern 

2/3 of the U.S. A tank mix of 3% Imazapyr 2SL + Garlon® 4 or Imazapyr 2SL is effective in the 

Northeastern U.S.

INVERT EMULSIONS 

Imazapyr 2SL can be applied as an invert emulsion carrier. The carrier is a thick invert water-in-oil spray 

emulsion designed to minimize spray drift and spray run-off, resulting in more herbicide on the target 

foliage. The spray emulsion may be formed in a single tank (batch mixing) or injected (in-line mixing). 

Consult the invert chemical label for proper mixing directions. DO NOT exceed 3 quarts/Acre of 

Imazapyr 2SL.

PRODUCT INFORMATION 

AmTide Imazapyr 2 SL is an aqueous solution to be mixed with water and a surfactant and applied as a 

spray solution to control undesirable vegetation growing within forestry sites and specified aquatic, 

industrial non-cropland sites, and railroad, utility, and highway rights-of-way, and non-agricultural fence 

rows. Aquatic sites consist of standing and flowing water, wetland, and riparian areas. Industrial noncropland sites include utility plant sites, petroleum tank farms, pumping installations, non-agricultural 

fence rows, storage areas, and non-irrigation ditchbanks. AmTide Imazapyr 2 SL may also be used for 

the establishment and maintenance of wildlife openings, for the release of unimproved Bermudagrass 

and Bahiagrass, for bareground weed control, and for use under certain paved surfaces. 

AmTide Imazapyr 2 SL may be applied on forestry sites that contain areas of temporary surface water 

caused by the collection of water between planting beds, in equipment ruts, or in other depressions 

created by forest management activities, except in the states of California and New York. It is permissible 

to treat drainage ditches, intermittent drainage, intermittently flooded low lying sites, seasonally dry flood 

plains, and transitional areas between upland and lowland sites when no water is present except in the 

states of California and New York. Only the edge of drainage ditches can be treated for drainage ditches 

that contain water. It is also perrnissible to treat marshes, swamps, and bogs after water has receded, as 

well as seasonally dry flood deltas, except in the states of California and New York. 

Herbicidal Activity. AmTide Imazapyr 2 SL will control most annual and perennial grasses and 

broadleaf weeds in addition to many brush and vine species with some residual control of undesirable 

species that germinate above the waterline. AmTide Imazapyr 2 SL is readily absorbed through 

emergent leaves and stems and is translocated rapidly throughout the plant with accumulation in the 

meristematic regions. For maximum activity, weeds should be growing vigorously at the time of 

application, and the spray solution should include a surfactant (see ADJUVANTS section for specific 

directions). Treated plants stop growing soon after spray application. 

Chlorosis appears first in the newest leaves, and necrosis spreads from this point. In perennials, the 

herbicide is translocated into, and kills, underground or submerged storage organs, which prevents 

regrowth. Chlorosis and tissue necrosis may not be apparent in some plant species until 2 or more 

weeks after application. Complete kill of plants may not occur for several weeks. Applications of AmTide 

Imazapyr 2 SL are rainfast one hour after treatment. 

Application Methods. AmTide Imazapyr 2 SL may be selectively applied by using low-volume directed 

application techniques or may be broadcast applied by using ground equipment, watercraft, or aircraft 

(aerial applications to aquatic sites must be made by helicopter). In addition, AmTide Imazapyr 2 SL 

may also be applied using cut stump, cut stem, and frill and girdle treatment techniques within noncropland, and aquatic sites (see AERIAL APPLICATIONS and GROUND APPLICATIONS sections for 

additional details). 

PRECAUTIONS FOR AVOIDING INJURY TO NON-TARGET PLANTS 

Untreated desirable plants can be affected by root uptake of AmTide Imazapyr 2 SL from treated soil. 

Injury or loss of desirable plants may result if AmTide Imazapyr 2 SL is applied on or near desirable 

plants, on areas where their roots extend, or in locations where the treated soil may be washed or moved 

into contact with their roots. When making applications along shorelines where desirable plants may be 

present, caution shou Id be exercised to avoid spray contact with their foliage or spray application to the 

soil in which they are rooted. Shoreline plants that have roots which extend into the water in an area 

where AmTide Imazapyr 2 SL has been applied generally will not be adversely affected by uptake of the 

herbicide from the water. 

. If treated vegetation is to be removed from the application site, DO NOT use the vegetative matter as 

mulch or compost on or around desirable species.

MANAGING OFF-TARGET MOVEMENT 

Aerial Applications 

• Applicators are required to use a coarse or coarser droplet size (A8ABE 8572) or, if specifically using 

a spinning atomizer nozzle applicators are required to use a volume mean d',ameter (VMD) of 385 

microns or greater for release heights below 10 feet. Applicators are required to use a very coarse or 

coarser droplet size or, if specifically using a spinning atomizer nozzle, applicators are required to use 

a VMD of 475 microns or greater for release heights above 10 feet. Applicators must consider the 

effects of nozzle orientation and flight speed when determining droplet size. 

• Applicators are required to use upwind swath displacement. 

• The boom length must not exceed 60% of the wingspan or 90% of the rotor blade diameter to reduce 

spray drift. 

• Applications with wind speeds less than 3 mph and with wind speeds greater than 10 mph are 

prohibited. 

• Applications into temperature inversions are prohibited. 

Ground Boom Applications 

• Applicators are required to use a nozzle height below 4 feet above ground or plant canopy and 

coarse or coarser droplet size (ASABE S572) or, if specifically using a spinning atomizer nozzle, 

applicators are required to use a volume mean diameter (VMD) of 385 microns or greater. 

• Applications with wind speeds greater than 10mph are prohibited. 

• Applications into temperature inversions are prohibited. 

Wind Erosion 

Avoid treating powdery, dry or light sandy soils when conditions are favorable for wind erosion. Under 

these conditions, the soil surface should first be settled by rainfall or irrigation. 

ADJUVANTS 

Postemergence applications of AmTide Imazapyr 2 SL require the addition of a spray adjuvant. When 

making aquatic applications, only spray adjuvants that are approved or appropriate for aquatic use must 

be utilized. 

Nonionic Surfactants. Use a nonionic surfactant (NIS) at the rate of 0.25% volume/volume (v/v) or 

higher (see manufacturer's label) of the spray solution (0.25% v/v is equivalent to 1 quart in 100 gallons). 

For best results, select a nonionic surfactant with an HLB (hydrophilic to lipophilic balance) ratio between 

12 and 17 with at least 70% surfactant in the formulated product (alcohols, fatty acids, oils, ethylene 

glycol or diethylene glycol shou Id not be considered as surfactants to meet the above requirements. 

Methylated Seed Oils or Vegetable Oil Concentrates. Instead of a surfactant, a methylated seed oil 

(MSO) or vegetable-based seed oil concentrate may be used at the rate of 1.5 to 2 pints per acre. When 

using spray volumes greater than 30 gallons per acre, methylated seed oil or vegetable-based seed oil 

concentrates should be mixed at a rate of 1 % of the total spray volume, or altematively use a nonionic 

surfactant as described above. Research indicates that these oils may aid in AmTide Imazapyr 2 SL 

deposition and uptake by plants under moisture or temperature stress. 

Silicone-based Surfactants. See manufacturer's label for specific rate directions. Silicone-based 

surfactants may reduce the surface tension of the spray droplet allowing greater spreading on the leaf 

surface as compared to conventional non ionic surfactants. However, some silicone-based surfactants 

may dry too quickly, limiting herbicide uptake. 

Fertilizer/Surfactant Blends: Nitrogen-based liquid fertilizers, such as 28%N, 32%N, 10-34-0 or 

ammonium sulfate, may be added at the rate of 2 to 3 pints per acre in combination with the labeled rate 

of non ionic surfactant, methylated seed oil or vegetable/seed oil concentrate. Do not use fertilizers in a 

tank mix without a non ionic surfactant, methylated seed oil or vegetable/seed oil concentrate.

47
( 

Invert Emulsions. AmTide Imazapyr 2 SL can be applied as an invert emulsion. The spray solution 

results in an invert (water-in-oil) spray emulsion designed to minimize spray drift and spray runoff, 

resulting in more herbicide on the target foliage. The spray emulsion may be formed in a single tank 

(batch mixing) or injected (in-line mixing). Consult the invert chemical label for proper mixing directions. 

Other. An antifoaming agent, spray pattern indicator, or drift-reducing agent may be applied at the 

product labeled rate if necessary or desired. 

TANK MIXES 

AmTide Imazapyr 2 SL may be tank mixed with other herbicides. 

Consult manufacturer's labels for specific rate restrictions and weeds controlled. Always follow the more 

restrictive label restrictions and precautions for all products used when making an application involving 

tank mixes. 

AERIAL APPLICATIONS 

All precautions should be taken to minimize or eliminate spray drift. Also see "MANAGING OFF-TARGET 

MOVEMENT" on the label. Both fixed-wing aircraft and helicopters can be used to apply AmTide 

Imazapyr 2 SL on non-cropland sites, but only helicopters can be used for aquatic applications. DO NOT 

make applications by fixed-wing aircraft or helicopter unless appropriate buffer zones can be maintained 

to prevent spray drift out of the target area, or when treating open tracts of land, spray drift as a result of 

fixed-wing aircraft application can be tolerated. Aerial equipment designed to minimize spray drift, such 

as helicopter equipped with a MicrofollTM boom, Thru-ValveTM boom, or raindrop nozzles, must be used 

and calibrated. Except when applying with a MicrofollTM boom, a drift control agent may be added at the 

specified label rate. Do not side trim with AmTide Imazapyr 2 SL unless death of treated tree can be 

tolerated. 

Uniformly apply the specified amount of AmTide Imazapyr 2 SL in 2 to 30 gallons of water per acre. A 

foam-reducing agent may be added at the labeled rate, if needed. 

IMPORTANT: Thoroughly clean application equipment, incJuding landing gear, immediately after use of 

this product. Prolonged exposure of this product to uncoated steel (except stainless steel) surfaces may 

result in corrosion and failure of the exposed part. The maintenance of an organic coating (paint) may 

prevent corrosion. 

FOLIAR APPLICATIONS 

Low-Volume Foliar Application 

GROUND APPLICATIONS 

Use equipment calibrated to deliver 5 to 20 gallons of spray solution per acre. To prepare the spray 

solution, thoroughly mix in water 0.5% to 5% AmTide Imazapyr 2 SL plus surfactant (see the 

ADJUVANTS section of this label for specific directions). A foam-reducing agent may be applied at the 

specified label rate, if needed. For control of difficult species (see Aquatic Weeds Controlled section 

and the Terrestrial Weeds Controlled by AmTide Imazapyr 2 SL section for relative susceptibility of 

weed species), use the higher concentrations of herbicide and/or spray volumes, but DO NOT apply more 

than 6 pints of AmTide Imazapyr 2 SL per acre in aquatic and non-cropland sites. Do not excessively 

wet foliage. See Spray Solution Mixing Guide for Low-Volume Foliar Applications for specified 

volumes of AmTide Imazapyr 2 SL and water. 

For low-volume foliar application, select proper nozzles to avoid over-application. Proper application is 

critical to ensure desirable results. Best results are achieved when the spray covers the crown and 

7

( ( 

approximately 70 percent of the plant. The use of an even, flat-fan tip with a spray angle of 40 degrees or 

less will aid in proper deposition. 

Recommended tip sizes include 4004E or 1504E. For a straight-stream and cone pattern, adjustable 

cone nozzles, such as 5500 X3 or 5500 X4, may be used. Attaching a rollover valve onto a Spraying 

Systems Model 30 gunjet or other similar spray gun allows for the use of both flat-fan and cone tips on 

the same gun. 

Moisten, but DO NOT drench target vegetation causing spray solution to run off. 

Low-volume Foliar Application with Backpacks 

For low-growing species, spray down on the crown, covering crown, and penetrating approximately 70% 

of the plant. 

For target species 4 to 8 feet tall, swipe the sides of target vegetation by directing spray to at least 2 sides 

of the plant in smooth vertical motions from the crown to the bottom. Make sure to cover the crown 

whenever possible. 

For target species over 8 feet tall, lace sides of the target vegetation by directing spray to at least 2 sides 

of the target in smooth zigzag motions from crown to bottom. 

Low-volume Foliar Application with Hydraulic Handgun Application Equipment 

Use the same technique as described above for Low-volume Foliar Application with Backpacks. 

For broadcast applications, simUlate a gentle rain near the top of target vegetation allowing spray to 

contact the crown and penetrate the target foliage without falling to the understory. Herbicide spray 

solution that contacts the understory may result in severe injury or death of plants in the understory.

High Volume Foliar Application 

For optimum performance when spraying medium-density to high-density vegetation, use equipment 

calibrated to deliver up to 100 gallons of spray solution per acre (GPA). Spray solutions exceeding 100 

GPA may result in excessive spray runoff, causing increased ground cover injury, and injury to desirable 

species. To prepare the spray solution, thoroughly mix AmTide Imazapyr 2 SL in water and add a 

surfactant (see ADJUVANTS section for specific directions and rates of surfactants). A foam-reduCing 

agent may be added at the labeled rate, if needed. For control of difficult species (see Aquatic Weeds 

Controlled chart and the Terrestrial Weeds Controlled by AmTide Imazapyr 2 SL section for relative

susceptibility·of weed species), use the higher concentrations of herbicide andlor spray volumes, but DO 

NOT apply more than 6 pints of AmTide Imazapyr 2 SL per acre in aquatic and non-cropland sites. 

Uniformly cover the foliage of the vegetation to be controlled, but DO NOT apply to runoff: Do not 

excessively wet foliage. 

Side Trimming 

DO NOT side trim with AmTide Imazapyr 2 SL unless severe injury or death of the treated tree can be 

tolerated. AmTide Imazapyr 2 SL is readily translocated and can result in death of the entire tree. 

CUT-SURFACE TREATMENTS 

AmTide Imazapyr 2 SL may be used to control undesirable woody vegetation by applying the AmTide 

Imazapyr 2 SL solution to the cambium area of freshly cut stump surfaces or to fresh cuts on the stem of 

the target woody vegetation. Applications can be made at any time of the year except during periods of 

heavy sap flow in the spring. DO NOT overapply solution causing runoff from the cut surface. 

Injury may occur to desirable woody plants if the shoots extend from the same root system or their root 

systems are grafted to those of the treated tree. 

Cut-surface Applications With Dilute and Concentrate Solutions 

AmTide Imazapry 2 SL may be mixed as either a concentrated or dilute solution. The dilute solution 

may be used for applications to the cut surface of the stump or to cuts on the stem of the target woody 

vegetation. Concentrated solutions may be used for applications to cuts on the stem. Use of the 

concentrated solution permits application to fewer cuts on the stem, especially for large-diameter trees. 

Follow the application instructions to determine proper application techniques for each type of solution. 

• To prepare a dilute solution, mix 8 to 12 fluid ounces of AmTide Imazapyr 2 SL with 1 gallon of 

water. The use of a surfactant or penetrating agent may improve uptake through partially callused 

cambiums. 

• To prepare concentrated solution, mix 2 quarts of AmTide Imazapyr 2 SL with no more than 1 quart 

of water. 

cut-Stump Treatments 

• Dilute Solutions. Spray or brush the solution onto the cambium area of the freshly cut stump 

surface. Ensure that the solution thoroughly wets the entire cambium area (the wood next to the bark 

of the stump). 

Cut-Stem (injection, hack and squirt) Treatments 

o Dilute Solutions. Using standard injection equipment, apply 1 milliliter of solution at each injection 

site around the tree with no more than 1-inch intervals between cut edges. Ensure that the injector 

completely penetrates the bark at each injection site. 

o Concentrate Solutions. Using standard injection equipment, apply 1 mmiliter of solution at each 

injection site. Make at least 1 injection cut for every 3 inches of Diameter at Breast Height (DBH) on 

the target tree. For example, a 3-inch DBH tree will receive 1 injection cut, and a 6-inch DBH tree will 

receive 2 injection cuts. On trees requiring more than 1 injection site, place the injection cuts at 

approximately equal intervals around the tree. 

Frill or Girdle Treatments 

• Using a hatchet, machete, or chainsaw, make cuts through the bark and completely around the tree 

to expose the cambium. The cut should angle downward extending into the cambium enough to 

expose at least 2 growth rings. Using a spray l3Pplicator or brush, apply a 25% to 100% solution of 

AmTide Imazapyr 2 SL into each cut until thoroughly wet. Avoid applying so much herbicide that 

runoff to the ground or water occurs.

NON-CROPLAND USES 

Applications may be made for the control of undesirable vegetatioD growing within industrial non-cropland 

sites. Industrial non-cropland sites include utility plant sites, petroleum tank farms, pumping installations, 

non-agricultural fence rows, storage areas, and non-irrigation ditchbanks. AmTide Imazapyr 2 SL may 

also be used for the establishment and maintenance of wildlife openings, for the release of unimproved 

Bermudagrass and Bahiagrass, for bareground weed control, and for use under certain paved surfaces. 

Applications to non-cropland areas that are not applicable to treatment of commercial timber or other

FOR THE SELECTIVE CONTROL OF 

UNDESIRABLE WEEDS IN UNIMPROVED 

BERMUDAGRASS AND BAHIAGRASS 

AmTide Imazapyr 2 SL may be used on unimproved Bermudagrass and Bahiagrass turf such as 

roadsides, utility rights-of-way, and other non-cropland industrial sites. The application of AmTide 

Imazapyr 2 SL on established common and coastal Bermudagrass and Bahiagrass provides control of 

labeled broadleaf and grass weeds. Competition from these weeds is eliminated, releasing the 

Bermudagrass and Bahiagrass. Treatment of Bermudagrass with AmTide Imazapyr 2 SL results in a 

compacted growth habit and seed-head inhibition. 

Uniformly apply with properly calibrated ground equipment using at least 10 gallons of water per acre. 

IMPORTANT: Temporary yellowing of grass may occur when treatment is made after growth 

commences. DO NOT add surfactant in excess of the specified rate (1 oz per 25 gallons of spray 

solution). DO NOT APPLY to grass during its first growing season. DO NOT APPLY to grass that is 

under stress from drought, disease, insects, or other causes. 

DOSAGE RATES AND TIMING 

Bermudagrass. Apply AmTide Imazapyr 2 SL at 6 to 12 ozs per acre when the Bermudagrass is 

dormant. Apply AmTide Imazapyr 2 SL at 6 to 8 ozs per acre after Bermudagrass has reached full 

green-up. Applications made during green-up will delay green-up. Include a surfactant in the spray 

solution (see IMPORTANT note above). 

For additional preemergence control of annual grasses and small-seeded broad leaf weeds, add 

Pendulum® Aquacap TM herbicide at the rate of 3.1 to 6.3 pints per acre. Consult the Pendulum 

Aquacap label for weeds controlled and for other use directions and precautions. 

For control of Johnsongrass in Bermudagrass turf, apply AmTide Imazapyr 2 SL at 8 ozs per acre, plus 

Roundup® herbicide at 12 ozs per acre, plus surfactant. For additional control of broadleaves and vines, 

Garlon® 3A may be added to the above mix at the rate of 1 to 2 pints per acre. Observe all precautions 

and restrictions on the Garlon® 3A and Roundup® labels. 

Bahiagrass. Apply AmTide Imazapyr 2 SL at 4 to 8 ozs per acre when the Bahiagrass is dormant or 

after the grass has initiated green-up but has not exceeded 25% green-up. Include a surfactant in the 

spray solution. (See ADJUVANTS section for specific directions on surfactants). 

Weeds Controlled in Unimproved Bermudagrass and Bahiagrass: 

Bedstraw (Galium spp.)

GRASS GROWTH AND SEED-HEAD SUPPRESSION 

AmTide Imazapyr 2 SL may be used to suppress growth and seed-head development of certain 

turfgrass in unimproved areas. When AmTide Imazapyr 2 SL is applied to desirable turf, it may result in 

temporary turf damage and/or discoloration. Effects to the desirable turf may vary with environmental 

conditions. For optimum performance, application should be made prior to culm elongation. Applications 

may be made before or after mowing. If applied prior to mowing, allow at least 3 days of active growth 

before mowing. If applied following a mowing, allow sufficient time for the grasses to recover before 

applying this product or injury may be amplified. 

DO NOT APPLY to turf under stress (drought, cold, insect damaged, etc.) or severe injury or death may 

occur. 

8ermudagrass. Apply AmTide Imazapyr 2 SL at 6 to 8 ozs per acre from early green-up to prior to 

seed-head initiation. DO NOT add a surfactant for this application. 

Cool Season Unimproved Turf. Apply AmTide Imazapyr 2 SL at 2 ozs per acre plus 0.25% nonionic 

surfactant. For increased suppression, AmTide Imazapyr 2 SL may be tank mixed with such products as 

Campaign® (24 ozs per acre) or Embark® (8 ozs per acre). Tank mixes may increase injury to desired 

turf. Consult each product label for specified turf species and other use directions and precautions. Tank 

mixes with 2, 4-0 or products containing 2,4-0 may decrease the effectiveness of AmTide Imazapyr 2 

SL. 

TOTAL VEGETATION CONTROL WHERE 

BARE GROUND IS DESIRED 

AmTide Imazapyr 2 SL is an effective herbicide for preemergence or postemergence control of many 

annual perennial broadleaf and grass weeds where bare ground is desired. AmTide Imazapyr 2 SL is 

particularly effective on hard-to-control perennial grasses. AmTide Imazapyr 2 SL herbicide at 1.5 to 6 

pints per acre can be used alone or in a tank mix with herbicides approved for use in bare ground. The 

degree and duration of control are dependent on the rate of AmTide Imazapyr 2 SL used, tank mix 

partner, the volume of carrier, soil texture, rainfall, and other conditions. 

Consult manufacturer labels for specific rates and weeds controlled. Always follow the more restrictive 

label restrictions and precautions for all products used when making an application involving tank mixes. 

Applications of AmTide Imazapyr 2 SL may be made any time of the year. Use equipment calibrated to 

deliver desired gallons per acre spray volume and uniformly distribute the spray pattern over the treated 

area. 

Postemergence Applications. Always use a spray adjuvant (see ADJUVANTS section of this label) 

when making a postemergence application. For optimum performance on tough-to-control annual 

grasses, applications should be made at a total volume of 100 gallons per acre or less. For quicker 

burndown or brown-out of target weeds, AmTide Imazapyr 2 SL may be tank mixed with Roundup 

herbiCide. Tank mixes with 2, 4-0, or products containing 2, 4-0, may reduce the perfonmance of 

AmTide Imazapyr 2 SL. Always follow the more restrictive label restrictions and precautions for all 

products used when tank mixing. 

Spot Treatments. AmTide Imazapyr 2 SL may be used as a follow-up treatment to control escapes or 

weed encroachment in a bareground situation. To prepare the spray solution, thoroughly mix in each 

gallon of water 0.5% to 5% AmTide Imazapyr 2 SL plus an adjuvant. For increased burndown, include 

Roundup as a tank mixture .. For added residual weed control, or to increase the weed spectrum, add

FOR CONTROL OF UNDESIRABLE WEEDS 

UNDER PAVED SURFACES 

AmTide Imazapyr 2 SL can be used under asphalt, pond liners and other paved areas, ONLY in 

industrial sites or where the pavement has a suitable barrier along the perimeter that prevents 

encroachment of roots of undesirable plants. 

Use AmTide Imazapyr 2 SL only where the area to be treated has been prepared according to good 

construction practices. If rhizomes, stolons, tubers or other vegetative plant parts are present in the site, 

remove them be scalping with a grader blade to a depth sufficient to ensure their complete removal. 

IMPORTANT: Follow AmTide Imazapyr 2 SL applications with paving as soon as possible. DO NOT 

apply where the chemical may contact the roots of desirable trees or other plants. 

Do not use this product under pavement on residential properties, such as driveways or parking lots, or 

for use in recreational areas, such as under bike or jogging paths, golf cart paths, or tennis courts, or 

where landscape plantings could be anticipated. 

Injury or death of desirable plants may result if this product is applied where roots are present or where 

roots may extend into the treated area. Roots of trees and shrubs may extend a considerable distance 

beyond the branch extremities (drip line). 

Apply to the soil surface only when final grade is established. DO NOT move soil following AmTide 

Imazapyr 2 SL application. 

Apply AmTide Imazapyr 2 SL in sufficient water (at least 100 gallons per acre) to ensure thorough and 

uniform wetting of the soil surface, including the shoulder areas. Add AmTide Imazapyr 2 SL at a rate·of 

6 pints per acre (2.2 fluid ounces per 1000 square feet) to clean water in the spray tank during the filling 

operation. Agitate before spraying. 

If the soil is not moist prior to treatment, incorporation of AmTide Imazapyr 2 SL is needed for herbicide 

activation. Incorporate ArnTide Imazapyr 2 SL into the soil to a depth of 4 to 6 inches using a rototiller or 

disc. Rainfall or irrigation of 1 inch will also provide uniform incorporation. DO NOT allow treated soil to 

wash or move into untreated areas. 

Spot Treatments and Crack and Crevice Treatments 

Use AmTide Imazapyr 2 SL as an initial or follow-up treatment control weed escapes or weed 

encroachment in a bareground situation, including cracks and crevices in paved surfaces such as 

roadways, runways, and parking areas. 

AQUATIC WEED CONTROL 

AmTide Imazapyr 2 SL may be applied for the control of floating and emergent undesirable vegetation 

(see the Aquatic Weeds Controlled and the Terrestrial Weeds Controlled by AmTide Imazapyr 2 SL 

section) in or near bodies of water that may be flowing, non-flowing, or transient. AmTide Imazapyr 2 

SL may be applied to aquatic sites that include lakes, rivers, streams, ponds, seeps, drainage ditches, 

canals, reservoirs, swamps, bogs, marshes, estuaries, bays, brackish water, transitional areas between 

terrestrial and aquatic sites, riparian sites, and seasonal wet areas. See PRODUCT USE 

PRECAUTIONS AND RESTRICTIONS section of this label for precautions, restrictions, and instructions 

on aquatic uses. 

Read and observe the following directions if aquatic sites are present in non-crop areas and are part of 

the intended treatment area: 

13 

54
( 

AmTide Imazapyr 2 SL must be applied to the emergent foliage of the target vegetation and has little-tono activity on submerged aquatic vegetation. AmTide Imazapyr 2 SL concentrations resulting from 

direct application to water are not expected to be of sufficient concentration nor duration to provide control 

of target vegetation. Application should be made in such a way as to maximize spray interception by the 

target vegetation while minimizing the amount of overs pray that enters water. 

AmTide Imazapyr 2 SL does not control plants that are completely submerged or have a majority of their 

foliage under water. 

AmTide Imazapyr 2 SL should be applied WITh surface or helicopter application equipment in"aminimum 

of 2 gallons of water per acre. When applying by helicopter, follow directions under the AERIAL 

APPLICATIONS section of this label; otherwise, refer to the section on GROUND APPLICATIONS when 

using surface equipment. 

Make applications to moving bodies of water while traveling upstream to prevent concentration of this 

herbicide in water. DO NOT apply to bodies of water of portions of bodies of water where emergent 

andlor floating weeds do not ex·,st. 

When application is to be made to target vegetation that covers a large percentage of the surface area of 

impounded water, treating the area in strips may avoid oxygen depletion due to decaying vegetation. 

Oxygen depletion may result in the suffocation of some sensITive aquatic organisms. If oxygen depletion 

is a concern, treat no more the % of the surface area of the water in a single operation and wait at least 

10 to 14 days between treatments. Begin treatment along the shore and proceed outward in bands to 

allow aquatic organisms to move into untreated areas. 

Avoid washoff of sprayed foliage by spray boat or recreational boat backwash for 1 hour after application. 

Apply AmTide Imazapyr 2 SL at 2 to 6 pints per acre depending on species present and weed density. 

DO NOT exceed the maximum label rate of 6 pints per acre (1.5 Ibs ae/A) per year. Use the higher 

labeled rates for heavy weed pressure. Consult the Aquatic Weeds Controlled section and the 

Terrestrial Weeds Controlled by AmTide Imazapyr 2 SL section of this label for specific rates. 

AmTide Imazapyr 2 SL may be applied as a draw-down treatment in areas described above. Apply 

AmTide Imazapyr 2 SL to weeds after water has been drained and allow 14 days before reintroduction 

of water.

Terrestrial Weeds Controlled by AmTide Imazapyr 2 SL herbicide 

In terrestrial sites, AmTide Imazapyr 2 SL will provide preemergence or postemergence control with 

residual control of the following target vegetation species at the rates listed. Residual control refers to 

control of newly germinating seedlings in both annuals and perennials. In general, annual weeds may be 

controlled by preemergence or postemergence applications of AmTide Imazapyr 2 SL. For established 

biennials and perennials, make postemergence applications of AmTide Imazapyr 2 SL. 

The rates shown below pertain to broadcast applications and indicate the relative sensitivity of these 

weeds. The relative sensitivity should be referenced when preparing low-volume spray solutions (see 

Low-volume Foliar Application sections of GROUND APPLICATIONS); low-volume applications may 

provide control of the target species with less AmTide Imazapyr 2 SL per acre than is shown for the 

broadcast treatments. Use AmTide Imazapyr 2 SL only in accordance with the directions on this label. 

17 

58
The relative sensitivity of the species listed following can also be used to determine the relative risk of 

causing nontarget plant injury if any of the species listed following are considered to be desirable within 

the area to be treated. 

Resistant Biotypes. Naturally occurring biotypes (a plant within a given species that has a slightly 

different by distinct genetic makeup from other plants of the same species) of some weeds listed on this 

label may not be effectively controlled. If naturally occurring, resistant biotypes are present in an area, 

AmTide Imazapyr 2 SL should be tank mixed or applied sequentially with an appropriate registered 

herbicide having a different mode of action to ensure control.

DO NOT plant seedlings of black spruce (PICea manana) or white spruce (Plcea glauca) on Sites that have been 

site prepared with a broadcast application of AmTide Imazapyr 2 SL or into the treated zone of spot or banded site 

preparation applications for three months following treatment or injury may occur. 

2 DO NOT plant seedlings of Red Pine (Pinus resinosa) on sites that have been site prepared with a broadcast 

application of AmTide Imazapyr 2 SL or into the treated zone of spot or banded site preparation applications for six 

months following treatment or injury may occur. 

Use the specified rate of AmTide Imazapyr 2 SL per acre applied as a broadcast foliar spray for longterm control of labeled woody plants and residual control of herbaceous weeds. Within 4 to 6 weeks of 

treatment, grasses and other herbaceous weeds will be controlled and may provide fuel to facilitate a site 

preparation burn, if desired, to controi conifers or other species tolerant to the herbicide. 

For tracts to be planted with loblolly, loblolly x pitch hybrid, longleaf pine, shortleaf pine, Virginia pine and 

slash pine, AmTide Imazapyr 2 SL may be applied at a rate of 64 oz per acre on areas that have little to 

22 

63
no resprouting vegetation because of recent management activities such as harvesting, mechanical 

shearing, burning piling or bedding. Applications must be made after September 1. 

MIXING and APPLICATION INSTRUCTIONS for SITE PREPARATION: 

Apply the specified rate of AmTide Imazapyr 2 SL per acre in 5 to 20 gallons of total spray carrier for 

helicopter applications or 5 to 40 gallons total spray carrier for mechanical or backpack ground spray 

applications. Enhanced brownout for burning and improved control of brush and grasses may be 

obtained by application of AmTide Imazapyr 2 SL in 12 to 50% oil:water (volume:volume) emulsion 

carrier. Use methylated or ethylated seed oils containing at least 50% esterified seed oil by volume. Mix 

AmTide Imazapyr 2 SL into the water portion of the carrier thoroughly, then add the oil and mix 

thoroughly again to obtain a uniform emulsion. Use the higher label rates of AmTide Imazapyr 2 SL and 

higher spray volumes when controlling particularly dense or multi-layered canopies or hardwood stands, 

or difficult to control species. Make applications during the growing season; beginning in the spring after 

full leaf expansion of the target weed or brush has occurred and complete applications before leaf drop in 

the fall. 

Tank mixes may be necessary for chemical control of conifers and other species tolerant to AmTide 

Imazapyr 2 SL in certain cases. Observe all precautions and restrictions on the product labels. Always 

follow the most restrictive label. Combinations with other products labeled for forest site preparation may 

kill certain plants such as legumes and blackberry, which are desirable for wildlife habitat. 

DO NOT plant seedlings of black spruce (Picea mariana) or white spruce (Picea g/auca) on sites that 

have been site prepared with a broadcast application of AmTide Imazapyr 2 SL or into the treated zone 

of spot or banded site preparation applications for three months following treatment or injury may occur. 

HELICOPTER SPRAY EQUIPMENT 

All precautions should be taken should be taken to minimize or eliminate spray drift. Applications should 

not be made under gusty conditions. The use of controlled droplet booms and nozzle configurations is 

recommended. 

IMPORTANT: DO NOT make applications by fixed wing aircraft. Maintain adequate buffer zones. 

Thoroughly clean application and mixing equipment, including landing gear, immediately after use. 

Prolonged exposure of this product to uncoated steel (except stainless steel) surfaces may result in 

corrosion and failure of the exposed part. 

HARDWOOD SITE PREPARATION TREATMENTS 

For site preparation prior to planting hardwood species in the southeast and gulf coast states (Virginia to 

Texas), use AmTide Imazapyr 2 SL at a rate of 48 oz per acre and spray before the end of July. Apply 

in an emulsion carrier with a minimum of 12% oil. DO NOT plant hardwood seedlings before January of 

the year following site preparation or injury may occur. 

DIRECTED FOLIAR APPLICATIONS 

FOR CONIFER RELEASE 

AmTide Imazapyr 2 SL may be applied as a directed spray using water or oil emulsion carrier for control 

and suppression of labeled brush and weed species. Directed spray applications may be made using low 

carrier volumes (generally 10 gallons total spray per acre or less) in labeled conifer stands of all ages by 

targeting the unwanted vegetation and avoiding direct application to the conifer. Ensure that the 

maximum labeled rates per acre listed for the conifer species are not exceeded. 

Use directed foliar applications of AmTide Imazapyr 2 SL for release of the following conifers from 

hardwood competition:

For applications directed to the foliage of undesirable brush mix 2 to 10% AmTide Imazapyr 2 SL in 

water. For brush species with thick leaf cuticles or difficult to control species use oil emulsion carrier 

containing 12 to 50%. by volume. specified oil diluents. Apply the spray solution or emulsion to at least 

2/3 of each hardwood crown using backpack sprayers or hand-held equipment. DO NOT spray to the 

point of runoff and avoid spraying the conifers for best results. For low volume foliar applications to 

control big leaf maple, use a 5% by volume AmTide Imazapyr 2 SL solution or emulsion. 

Some minor conifer growth inhibttion may be observed when release treatments are made during periods 

of active conifer growth. To minimize potential conifer height growth inhibition, release treatments may be 

made late in the growing season after formation of final conifer resting buds. To prevent possibility of 

conifer injury, DO NOT apply AmTide Imazapyr 2 SL when conifers are under stress from drought, 

diseases, animal or winter injury, or other stresses reducing conifer vigor. 

Injury may occur to non-target or desirable hardwoods if they extend from the same root system as 

treated stems, or their root systems are grafted to those of the treated tree, or if their roots extend into the 

soil near treated trees. 

BAG AND BROADCAST APPLICATIONS FOR 

CONIFER RELEASE 

In Douglas-fir and Ponderosa pine stands, broadcast applications of AmTide Imazapyr 2 SL up to 32 oz 

per acre are permissible when the trees are covered by bags prior to the application. The bags must 

prevent the spray mix from contacting the conifer foliage. For improved control of brush species, 

particularly evergreens, add a suitable seed oil at 5 to 12% by volume. On sites with coarse textured 

soils (e.g. decomposed granite, pumice, sandy or rocky sites) or low levels of soil organic matter 

(generally 5% or less) significant conifer growth inhibition and mortality is possible. DO NOT use this 

treatment on these types of sites if conifer growth inhibition and mortality cannot be tolerated. 

LATE ROTATION VEGETATION CONTROL 

IN WESTERN CONIFERS 

In California, the Pacific Northwest and Inland Northwest, broadcast aerial applications of AmTide 

Imazapyr 2 SL up to 48 oz per acre are permissible in conifer stands that are targeted for harvesting the 

year following treatment. Use a minimum spray volume of 15 gallons per acre. For improved control of 

brush species, particularly evergreens, add a suitable seed oil at 5 to 12% by volume. Significant conifer 

injury or mortality must be expected. DO NOT use this treatment if conifer injury or mortality cannot be 

tolerated.

UNDERSTORY BROADCAST APPLICATIONS 

FOR MID-ROTATION RELEASE 

AmTide Imazapyr 2 SL may be applied as a broadcast application below the conifer canopy to control 

understory brush and suppress trees for labeled species. Ground spray machinery or hand held 

equipment may be used to broadcast AmTide Imazapyr 2 SL in water or oil emulsion carrier below the 

crop tree canopy in a manner as to minimize spray contact by the live crown of crop trees. 

Ensure that maximum labeled rates per acre listed for crop species below are not exceeded.

Label changes for AmTide Imazapyr 2 SL 

1. In the ingredient statement, at the bottom, change the equivalence of acid to "Contains 

2.591bs of the active ingredient (a.i.), isopropylamine salt ofimazapyr or 2.11bs imazapyr 

acid equivalent per gallon." The technical product has 98% in its name, but the nominal 

concentration is 98.6%. Submit a revised CSF correcting the 23.06 in colunm 13 to 22.92. 

Then adjust the diluent to give you 100%. With this correction, the nominal concentration 

for the ai as the salt is correct. 

2. On page 2 oflabel, under "ENVIRONMENTAL HAZARDS", change the third sentence 

to "Do not apply directly to bodies of water except as specified in this label." This product is 

mixed in water. 

3. On page 3, take the bullets under "IMPORTANT" and move them under 

"PRECAUTIONS AND RESTRICTIONS". Remove "IMPORTANT" and the 4th bullet (it's 

redundant). This product will kill trees and shrubs. Add a restriction to tell applicator the 

minimum distance to apply this product from desirable trees and shrubs, for example, if 

toxicity consideration permitting, "Do not apply within drip-line of desirable trees or areas 

that will wash AmTide Imazapyr 2 SL into roots of desirable trees and shrubs." 

4. On page 4, change "Non-cropland Sites" to "Nonfood/feed-cropland Sites". 

Under "Aquatic Sites" add the bullet "DO NOT apply to bodies of water or portions of 

bodies of water where emergent and/or floating weeds do not exist. AmTide Imazapyr 2 SL 

has no effect on submerged aquatic vegetation." 

Remove the last sentence, beginning with "When applications are made within 500 feet. .. " 

of the last bullet under "Aquatic Sites". The sentence contradicts and is less restrictive than 

previous sentences of bullet. 

5. On page 7, after the first sentence under "AERIAL APPLICATIONS", add "Also see 

"MANAGING OFF-TARGET MOVEMENT" on the label." 

6. On page 15, change the fifth paragraph to "Make applications to moving bodies of water 

while traveling upstream to prevent concentration of this herbicide in water." 

7. On pages 26 and 27, change the reference to the use of diesel oil and penetration oil, under 

"CUT STUMP TREATMENTS", "FRILL OR GIRDLE TREATMENTS", and "LOW 

VOLUME BASAL BARK TREATEMENTS" to "" . spring oil or food/feed seed oil..."

Mike, 

This salt is for imazapyr does not have established tolerances for any 

food or feed crops including grasses (40CFR180.500). I know there are 

products out there registered for grass, and these will have to be dealt 

with. I have been informed by our lawyers that there is no 

discretionary authority when it comes to tolerances, so let's get the 

current revised label registered. Getting the isopropylamine salt 

included in the tolerance expression will take much longer then I 

believe you care to wait. Does this sound reasonable to go ahead and 

register the product without the grass? 

The issue got reserved with the removal of grasses, so I didn l t bother 

you with this before.

Phil, 

11m pretty sure I know the answer to the question 11m about to ask 

however AmTide has requested I contact you regarding their AmTide 

Imazapyr 2SL application. AmTide would like to substitute a cleared 

inert (cleared per 180.950) for the inert currently in the formulation 

76
which is not cleared for food use. This would allow AmTide to keep the 

pasture and rangeland language on the label. Is it too late to send 

revised CSF's and label? Obviously AmTide would not want to run the 

risk of having to extend the current PRIA date by taking action this 

late in the review process. I could have the documents to you today if 

it's possible. If not, we'll deal with the issue once the registration 

has been granted.

Mike, 

One inert, the mixture is cleared, but the other is not. At this point, 

the package is not complete, and if you wish to submit a revised label, 

start the PRIA clock when a revised label is received. Otherwise a not 

grant or deny will have to be written up. I'm not sure, if we don't get 

something from you very soon, whether the original PRIA date will be met 

by Technical Review Branch, a revised label resubmitted for approval and 

stamping if TRB approves, and meet the existing PRIA date without 

extending it. We have been told we will not be stamping any labels 

"Approved with Comments", if the draft label requires changes.

I was told by AmTide yesterday the inert ingredient supplier was working 

with the Agency on having the two inerts in question cleared for food 

use and it may have been completed yesterday. Have you heard anything 

on this?

Mike, 

Please go ahead and email the revised label to me. The PRIA date right 

now is 2/24/2011. It may slip because package wasn't sent in with a 

proper label for the product. I will put the product chemistry, waiver 

requests, and cited acute tax into review as soon as I receive the 

revised label without the pasture and rangeland uses. We will move 

forward using the original PRIA date. 

I have not completed the review of the label. The comments I gave you 

are all that's available right now.

AmTide Imazapyr 2 SL (EPA File Symbol NO. 

Thought I would email you as you are more than likely gone for the day. 

AmTide has elected to remove pasture and rangeland language from the 

AmTide Imazapyr 2 SL label in an attempt to avoid any delays in the PRIA 

timing (rIll also add IINon-Agricultural ll to fence rows as you indicated 

this morning). Any other changes to the label? May I email you a 

revised label or should it go through front end (5 copies)?

Mike, 

One inert, the mixture is cleared, but the other is not. At this point, the package is not complete, and if you 

wish to submit a revised label, start the PRIA clock when a revised label is received. Otherwise a not 

grant or deny will have to be written up. I'm not sure, if we don't get something from you very soon, 

whether the original PRIA date will be met by Technical Review Branch, a revised label resubmitted for 

approval and stamping if TRB approves, and meet the existing PRIA date without extending it. We have 

been told we will not be stamping any labels "Approved with Comments", if the draft label requires 

changes.

Mike, 

Please go ahead and email the revised label to me. The PRIA date right 

now is 2/24/2011. It may slip because package wasn't sent in with a 

proper label for the product. I will put the product chemistry, waiver 

requests, and cited acute tax into review as soon as I receive the 

revised label without the pasture and rangeland uses. We will move 

93
forward using the original PRIA date. 

I have not completed the review of the label. The comments I gave you 

are all that's available right now.

Thought I would email you as you are more than likely gone for the day. 

AmTide has elected to remove pasture and rangeland language from the 

AmTide Imazapyr 2 SL label in an attempt to avoid any delays in the PRIA 

timing (I'll also add "Non-Agricultural" to fencerows as you indicated 

this morning). Any other changes to the label? May I email you a 

revised label or should it go through front end (5 copies)?

Comments:

- Footnotes 

A. During the 21 day initial content review, all eSFs will be reviewed to determine 

whether all inerts listed, including fragrances, are approved for the proposed uses. If an 

unapproved inert is identified, the applicant must either 1) resolve the inert issue by, for 

example, removing the inert, substituting it with an approved inert, submitting 

documentation that EPA approved the inert for the proposed pesticidal uses, correcting 

mistakes on the eSF, etc. or 2) provide the data to support OPP approval of the inert or 3) 

withdraw the application. Removing or substituting an inert ingredient will require a new 

eSF and may require submission of data. All information, forms. data and 

documentation resolving the inert issue must have been received by the Agency or the 

application withdrawn within the 21 day period, otherwise, the Agency will reject the 

application as described below. 

To successfully complete this aspect of the 21 day initial content screen, applicants are 

strongly encouraged to verify that all inert ingredients have been approved for the 

application's uses even if a product is currently registered by consulting the inert Web

( 

site [link to http://www.epa.gov/opprdOOllinerts/lists.html] and if the inert is not 

approved, to obtain the necessary inert approval prior to submitting an application 

to register a pesticide product containing that inert ingredient. Some inert 

ingredients ,are no longer approved for food uses or certain types of uses. The name 

andlor CAS number on a CSF must match the name and CAS number on this web site. 

Simple typographical errors in the name or CAS number have resulted in processing 

delays. 

If an inert is not listed on the inert ingredient web site and the applicant believes that the 

inert has been approved, the applicant should contact the Inert Ingredient Assessment 

Branch (IIAB) at inertsbranch@epa.govandresolvetheissue. Copies of the 

correspondence with IIAB resolving the issue should accompany the application. All 

new inerts except PIP inerts are reviewed by IIAB. The IIAB should also be contacted 

for any questions on what supporting data needs to be submitted for and the Agency's 

inert review process. Questions on PIP inerts should be directed to the Chief of 

Microbial Pesticides Branch [Link to 

http://www.epa.gov/oppbppdllbiopesticides/contactsbppd.htm]. 

When a brand, trade, or proprietary name of an inert ingredient is listed on a CSF, 

additional information such as an alternate name of the inert, CAS number or other 

information [link to http://www.epa.gov/opprdOOllinerts/tips.pdf] must also be included 

to enable the Agency to determine if it has been approved. Each component of an inert 

mixture (including a fragrance) must be identified. In some cases, the supplier of the 

mixture or fragrance may need to provide this information to the Agency. Prior to the 

Agency's receipt of an application, applicants must arrange with a proprietary mixture or 

fragrance supplier to provide the component information to the Agency or prompt! y upon 

EPA's request. !fthe inert ingredients in a proprietary blend (including fragrances) 

cannot or are not identified or provided within the 21-day content review period, the 

Agency will reject the application. 

During the 21 day content review, applicants should submit information to the individual 

identified by the Agency when the applicant is informed of an unapproved inert. 

Unapproved Inerts Identified on CSFs 

All applications except conventional new products and PIPs 

Once an unapproved inert is identified on a CSF, the Agency will contact the 

applicant with the following options: 

1. Correct the application by, for instance, correcting the inert's identity or CAS 

number, providing documentation that the inert has been approved, or 

removing the unapproved inert from the CSF or replacing it with one that is 

approved for the application's uses; or 

2. Submit the information and data needed for the Agency to approve the 

unapproved inert. If this option is selected and implemented, the Agency may 

request an extension in the PRIA decision review timeframe to accommodate 

the inert review/approval process; 

4 

99
( 

3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

If none of these options is selected and implemented by the applicant within the 

21 day content review period, the Agency will reject the application and retain 

25 % of the full fee of the category identified. 

Conventional New Product Applications 

When the Registration Division identifies an unapproved inert on a CSF with an 

application for a new product that the applicant has not identified as requiring an 

inert approval (R311, R312 or R313), it will contact the applicant with the 

following options: 

1. Correct the application by, for instance, correcting the inert's identity or CAS 

number, providing documentation that the inert has been approved, or 

removing the unapproved inert from the CSF or replacing it with one that is 

approved for the application's uses; or 

2. Submit the information and data needed for the Agency to approve the 

unapproved inert, including any required petition to establish or amend a 

tolerance or exemption from a tolerance. (This option may change the PRIA 

category for the application, which could require a longer decision review 

time and a larger fee. If additional fees are due, they must be received by the 

Agency within the 21 day content review period.) 

3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

If none of the above options is selected and implemented during the 21-day 

content-review period, the Agency will reject the application and retain 25% of 

the appropriate fee for the new product-inert approval category. 

PIP Applications 

When the Biopesticide and Pollution Prevention Division identifies an 

unapproved inert on a PIP CSF and a request to approve the inert does not 

accompany the application, it will contact the applicant with the following 

options: 

1. Correct the application by, for instance, correcting the spelling or name of the 

inert to that in 40 CPR 174, or providing documentation that the inert has been 

approved; or 

2. Submit the information and data needed for the Agency to approve the 

unapproved inert. If an inert ingredient tolerance exemption petition is 

required, the petition must be received by the Agency and the B903 fee paid 

within the 21 day period. If this option is selected and implemented, the 

Agency will discuss harmonizing the timeframe for both actions. 

5 

100
( 

3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

If none of the above options is selected and implemented during the 21 day 

content review period, the Agency will reject the application and retain 25% of 

the fee. 

B. A policy on documentation of offers to pay is still being developed, however, for a 

me-too or fast track (similar/identical) new product, R300 or A530, an application 

without the necessary authorizations of offers to pay will be placed into either R301 or 

A531. The Agency recommends that authorizations of offers to pay be submitted with 

other PRIA applications to avoid delays in the Agency's decision. 

C. Biopesticide applicants are advised to contact the Agency and discuss study waivers 

prior to submitting their application to the Agency. Documentation of such discussions 

should be submitted with the study waiver.
