### mile upstream ofan active potable water intake in flowing water (i.e., river, stream, etc.) orwithin 11, 

### miles ofan 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 orwater 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 ofanalysis 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

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 undercertain paved surfaces. Imazapyr 2SL 

### may be applied on forestry sites that contain areas of temporary surface water caused by the collection ofwater between planting beds, in equipment ruts, or in other depressions created by forest management activities, except in the states ofCalifornia 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 afterwater has receded, as well as seasonally dryflood deltas, except in the states ofCalifornia and NewYork. Herbicidal Activity. Imazapyr 2SL 

### will control most annual and perennial grasses and broadleafweeds 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 afterspray 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 houraftertreatment. 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 FORAVOIDING INJURYTO NON-TARGET PLANTS
Untreated desirable plants can be affected by root uptake of Imazapyr 2SL 

### from treated soil. Injury or loss ofdesirable 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 generallywill not be adversely affected by uptake ofthe 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 orcoarser droplet size (ASABE S572) or, ifspecifically using a spinning atomizer nozzle applicators are required to use a volume mean diameter (VMD) of 385 microns orgreaterfor release heights below 10 feet. Applicators are required to use a very coarse or coarser droplet size or, ifspecifically using a spinning atomizer nozzle, applicators are required to use
5

### a VMD of 475 microns or greater for release heights above 10 feet. Applicators must consider the effects ofnozzle orientation and fiight speed when determining droplet size. • Applicators are required to use upwind swath displacement. • The boom length must not exceed 60% ofthe wingspan or 90% ofthe 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) of385 microns or greater. • Applications with wind speeds greaterthan 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 nonionic surfactant (NIS) at the rate of 0.25% volume/volume (v/v) or higher (see manufacturer's label) ofthe 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 ordiethylene 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 ortemperature 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 nonionic 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 mixwithout a nonionic surfactant, methylated seed oil orvegetable/seed oil concentrate. Invert Emulsions. Imazapyr2SL 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

### Other. An antifoaming agent, spray pattern indicator, or drift-reducing agent may be applied at the product labeled rate ifnecessary or desired. 

### TANK MIXES Imazapyr2SL 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 oreliminate 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. Exceptwhen applying with a MicrofojITM boom, a drift control agent may be added at the specified label rate. Do not side trim with Imazapyr2SL unless death oftreated 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, ifneeded. IMPORTANT: Thoroughly clean application equipment, including landing gear, immediately after use of this product. Prolonged exposure ofthis 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.

FOLIARAPPLICATIONS Low-Volume FoliarApplication 

### 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 ofweed 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 ofthe plant. The use ofan even, flat-fan tip with a spray angle of40 degrees or less will aid in properdeposition. 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 FoliarApplicationwith Backpacks For low-growing species, spray down on the crown, covering crown, and penetrating approximately 70% ofthe plant. Fortarget species 4to 8feet tall, swipe the sides oftarget 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. Fortarget species over 8 feet tall, lace sides ofthe target vegetation by directing spray to at least 2 sides ofthe target in smooth zigzag motions from crown to bottom. Low-volume FoliarApplicationwith Hydraulic Handgun Application Equipment Use the same technique as described above for Low-volume FoliarApplication 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. Spray Solution Mixing Guide for

High Volume FoliarApplication For optimum performance when spraying medium-density to high-density vegetation, use equipment calibrated to deliver up to 100 gallons ofspray 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 ofweed 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 ofthe treated tree can be tolerated. Imazapyr2SL is readily translocated and can result in death ofthe 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 ofthe year except during periods of heavy sap flow in the spring. DO NOT

### overapply solution causing runofffrom the cut surface. Injury may occur to desirable woody plants ifthe shoots extend from the same root system or their root systems are grafted to those ofthe treated tree.
Cut-surface Applications With Dilute and Concentrate Solutions Imazapyr2 SL 

### may be mixed as either aconcentrated ordilute 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 ofsolution.

• To 

### prepare a dilute solution, mix 8 to 12 fluid ounces of Imazapyr 2SL 

### with 1 gallon ofwater. The use ofa surfactant or penetrating agent may improve uptake through partially callused cambiums. • To 

### prepare concentrated solution, mix 2 quarts of Imazapyr2SL

### with no more than 1 quart ofwater. 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 nextto the bark ofthe 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

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 broadleaf 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 ofwater 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

### DOSAGE RATES AND TIMING Bermudagrass. Apply Imazapyr2SL 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 broadleaf weeds, add Pendulum® Aquacap

### TM herbicide at the rate of 3.1 to 6.3 pints per acre. Consult the Pendulum Aquacap label forweeds 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 1to 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 forspecific 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. Ifapplied prior to mowing, allow at least 3 days of active growth before mowing. Ifapplied 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 surfactantforthis application. Cool Season Unimproved Turf. Apply Imazapyr 2SL at 2 ozs per acre plus 0.25% nonionic surfactant. For increased suppression, Imazapyr2SL 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 Imazapyr2SL. 

### TOTALVEGETATION CONTROLWHERE BARE GROUND IS DESIRED Imazapyr 2SL is an effective herbicide for preemergence or postemergence control of many annual perennial broadleaf 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 ofthe year. Use equipment calibrated to deliver desired gallons per acre spray volume and uniformly distribute the spray pattern overthe 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 diuron. Always follow the more restrictive label restrictions and precautions for all products when tank mixing. 

### FOR CONTROL OF UNDESIRABLE WEEDS UNDER PAVED SURFACES Imazapyr2SL 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 othervegetative 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 Imazapyr2SL applications with paving as soon as possible. DO NOT apply where the chemical may contact the roots ofdesirable 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).

### 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 ofwater 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 ofthis 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: Imazapyr2SL 

### must be applied to the emergent foliage ofthe 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 ofoverspray that enters water. Imazapyr 2SL 

### does not control plants that are completely submerged or have a majority of their foliage underwater. 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 ofthis 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/orfloating weeds do not exist. When application is to be made to target vegetation that covers a large percentage ofthe 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

Terrestrial Weeds Controlled by Imazapyr2SL herbicide 

### In terrestrial sites, Imazapyr 2SL 

### will provide preemergence or postemergence control with residual control ofthe 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 ofaction to ensure control.

conifer injury, DO NOT apply Imazapyr 2SL when conifers are under stress from drought, diseases, animal orwinter injury, or otherstresses reducing conifervigor. Injury may occur to non-target or desirable hardwoods if they extend from the same root system as treated stems, ortheir root systems are grafted to those ofthe treated tree, or iftheir roots extend into the soil neartreated trees. 

### BAG AND BROADCASTAPPLICATIONS 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 ofsites ifconifer 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 ifconifer injury or mortality cannot be tolerated.



### UNDERSTORY BROADCASTAPPLICATIONS FOR MID-ROTATION RELEASE Imazapyr2SL may be applied as a broadcast application below the conifer canopy to control understory brush and suppress trees for labeled species.

PRODUCT INFORMATION
AmTide Imazapyr2 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 oftemporary 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 NewYork. 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 ofCalifornia and NewYork. Onlythe edge ofdrainage ditches can be treated for drainage ditches that contain water. It is also perrnissible to treat marshes, swamps, and bogs afterwater has receded, as well as seasonally dryflood deltas, except in the states of California and NewYork. 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 afterspray 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 afterapplication. Complete kill of plants may not occurforseveral weeks. Applications ofAmTide Imazapyr2SL are rainfast one hour aftertreatment. Application Methods. AmTide Imazapyr2 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 FORAVOIDING INJURY TO NON-TARGET PLANTS
Untreated desirable plants can be affected by root uptake ofAmTide 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 shouId 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 Imazapyr2 SL has been applied generally will not be adversely affected by uptake ofthe herbicide from the water.

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

mulch orcompost on or around desirable species.



### 5MANAGING OFF-TARGET MOVEMENT Aerial Applications • Applicators are required to use a coarse or coarser droplet size (A8ABE 8572) or, ifspecifically using a spinning atomizer nozzle applicators are required to use a volume mean d',ameter (VMD) of 385 microns orgreaterfor release heights below 10 feet. Applicators are required to use avery coarse or coarser droplet size or, ifspecifically 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% ofthe wingspan or 90% ofthe rotor blade diameterto 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 BoomApplications • 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 avolume mean diameter (VMD) of385 microns or greater. • Applications with wind speeds greaterthan 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 ofAmTide 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) ofthe 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 ordiethylene glycol shouId not be considered as surfactants to meet the above requirements. Methylated Seed Oils orVegetable 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 ortemperature 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 nonionic surfactants. However, some silicone-based surfactants may drytoo 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 of2 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 mixwithout a nonionic surfactant, methylated seed oil orvegetable/seed oil concentrate.

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) orinjected (in-line mixing). Consultthe 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 ordesired. 

### TANK MIXES
AmTide Imazapyr2 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 oreliminate spray drift. Also see "MANAGING OFF-TARGET MOVEMENT" on the label. Both fixed-wing aircraft and helicopters can be used to apply AmTide Imazapyr2 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 ofthe target area, orwhen 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 ofAmTide Imazapyr2 SL in 2 to 30 gallons ofwater 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 ofthis 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.

FOLIARAPPLICATIONS Low-Volume FoliarApplication 

### GROUNDAPPLICATIONS

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 ofthis 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 higherconcentrations of herbicide and/or sprayvolumes, but DO NOT apply more than 6 pints ofAmTide 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 ofAmTide Imazapyr2 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

approximately 70 percent ofthe plant. The use ofan even, flat-fan tip with a spray angle of40 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 FoliarApplication with Backpacks For low-growing species, spray down on the crown, covering crown, and penetrating approximately 70% ofthe plant. For target species 4 to 8 feet tall, swipe the sides oftarget vegetation by directing sprayto at least 2 sides of the plant in smooth vertical motions from the crown to the bottom. Make sure to cover the crown wheneverpossible. For target species over8 feet tall, lace sides ofthe target vegetation by directing spray to at least 2 sides ofthe target in smooth zigzag motions from crown to bottom. Low-volume FoliarApplication with Hydraulic HandgunApplication Equipment Use the same technique as described abovefor Low-volume FoliarApplication 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 ordeath of plants in the understory.

susceptibility·ofweed species), use the higher concentrations of herbicide andlorspray 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 excessivelywet foliage. SideTrimming DO NOT side trim with AmTide Imazapyr 2 SL unless severe injury or death ofthe treated tree can be tolerated. AmTide Imazapyr2 SL is readily translocated and can result in death ofthe 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 offreshly cut stump surfaces orto fresh cuts on the stem of the target woody vegetation. Applications can be made at any time ofthe year except during periods of heavy sap flow in the spring. DO NOT overapply solution causing runofffrom 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 tothose ofthe treated tree. Cut-surface ApplicationsWith 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 ofthe stump or to cuts on the stem ofthe 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. Followthe application instructions to determine proper application techniques for each type ofsolution.

• 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 1quart ofwater. 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 ofthe stump). Cut-Stem (injection, hackand 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 orGirdleTreatments • 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 runofftothe ground orwater occurs.

### FOR THE SELECTIVE CONTROL OF UNDESIRABLEWEEDS 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 ofwater 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 understress from drought, disease, insects, or othercauses. 

### 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 broadleaf weeds, add Pendulum® Aquacap

### TM herbicide at the rate of 3.1 to 6.3 pints per acre. Consult the Pendulum Aquacap label forweeds controlled and forother use directions and precautions. For control ofJohnsongrass in Bermudagrass turf, apply AmTide Imazapyr 2 SL at 8 ozs per acre, plus Roundup® herbicide at 12 ozs peracre, plus surfactant. Foradditional control of broadleaves and vines, Garlon® 3A may be added to the above mix at the rate of 1to 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 forspecific directions on surfactants).

### 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 surfactantforthis application. Cool Season Unimproved Turf. Apply AmTide Imazapyr 2 SL at 2 ozs per acre plus 0.25% nonionic surfactant. For increased suppression, AmTide Imazapyr2 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 forspecified turf species and other use directions and precautions. Tank mixes with 2, 4-0 or products containing 2,4-0 may decrease the effectiveness ofAmTide Imazapyr 2 SL. 

### TOTALVEGETATION CONTROLWHERE 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 ofcarrier, 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 ofAmTide Imazapyr2 SL may be made anytime ofthe year. Use equipment calibrated to deliver desired gallons per acre spray volume and uniformly distributethe 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 ofwater 0.5% to 5% AmTide Imazapyr2 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 Pendulum Aquacap herbicide, Overdrive® herbicide or diuron. Always follow the more restrictive label restrictions and precautions for all products when tank mixing.

FOR CONTROL OF UNDESIRABLEWEEDS 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 othervegetative plant parts are present in the site, remove them be scalping with a grader blade to a depth sufficient to ensuretheir complete removal. IMPORTANT: Follow AmTide Imazapyr 2 SL applications with paving as soon as possible. DO NOT applywhere the chemical may contact the roots ofdesirable trees or otherplants. 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 orjogging 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 thetreated area. Roots oftrees 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 Imazapyr2 SL application. Apply AmTide Imazapyr2 SL in sufficient water (at least 100 gallons per acre) to ensure thorough and uniform wetting ofthe soil surface, including the shoulderareas. Add AmTide Imazapyr2 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. Ifthe soil is not moist priorto treatment, incorporation ofAmTide Imazapyr 2 SL is needed for herbicide activation. IncorporateArnTide Imazapyr2 SL into the soil to a depth of4to 6 inches using a rototilleror disc. Rainfall orirrigation of 1 inch will also provide uniform incorporation. DO NOT allow treated soil to wash or move into untreated areas. SpotTreatments and Crack and CreviceTreatments 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.

Terrestrial Weeds Controlled byAmTide Imazapyr2 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 orpostemergence applications ofAmTide Imazapyr 2 SL. Forestablished biennials and perennials, make postemergence applications ofAmTide Imazapyr2 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 2SL only in accordance with the directions on this label.



### 17The relative sensitivity of the species listed following can also be used to determine the relative risk of causing nontarget plant injury if any ofthe 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 ofthe 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 ofaction to ensure control.

2 DO NOT plant seedlings of Red Pine (Pinus resinosa) on sites that have been site prepared with a broadcast application ofAmTide Imazapyr 2 SL or into the treated zone ofspot 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, ifdesired, to controi conifers orother species tolerant to the herbicide. For tracts to be planted with loblolly, loblollyx pitch hybrid, longleaf pine, shortleaf pine, Virginia pine and slash pine, AmTide Imazapyr2 SL may be applied at a rate of

### 64 oz per acre on areas that have little to


### 22no 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 INSTRUCTIONSforSITE PREPARATION: Apply the specified rate ofAmTide 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 Imazapyr2 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 leafexpansion ofthe target weed or brush has occurred and complete applications before leafdrop in thefall. 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 followthe most restrictive label. Combinations with other products labeled forforest site preparation may kill certain plants such as legumes and blackberry, which are desirableforwildlife 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 ofAmTide Imazapyr2 SL or into the treated zone ofspot or banded site preparation applications for three months following treatment or injury may occur.


### HELICOPTERSPRAY 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 ofthe 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 Imazapyr2 SL at a rate of48 oz per acre and spray before the end ofJuly. Apply in an emulsion carrierwith a minimum of 12% oil. DO NOT plant hardwood seedlings before January of the yearfollowing site preparation or injury mayoccur. 

### DIRECTED FOLIARAPPLICATIONS FOR CONIFER RELEASE AmTide Imazapyr2 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 forthe conifer species are not exceeded.

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 orwinter injury, or other stresses reducing conifervigor. 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 ofthe treated tree, or iftheir roots extend into the soil neartreated trees. 

### BAG AND BROADCASTAPPLICATIONS FOR CONIFER RELEASE In Douglas-fir and Ponderosa pine stands, broadcast applications ofAmTide 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 ofsites ifconifergrowth 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.

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 formulationwhich 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. Regards,

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.

## - Mike, One inert, the mixture is cleared, butthe other is not. Atthis point, the package is notcomplete, and ifyou wish to submita revised label, startthe PRIA clockwhen a revised label is received. Otherwise a not grantordenywill have to be written up. I'm notsure, ifwe don'tgetsomething from you verysoon, whetherthe original PRIAdatewill be met by Technical Review Branch, a revised label resubmitted for approval and stamping ifTRB approves, and meetthe existing PRIAdatewithout extending it. We have been told wewill not be stamping any labels "Approved with Comments", ifthe draft label requires changes. Thanks, Philip (Phil) V. Errico, Senior Chemist U. S.
