Dear Polly, 

 

In 2011, quite a few acres of alfalfa were treated with Dimilin under the Section 18 and I anticipate that it will 

get even greater use in 2012 if available. In Fremont County we have infrequent grasshopper outbreaks, 

maybe once every 25 to 30 years. Grasshopper populations were very high on cropland in 2009, but it was at 

least 10 time worse in both numbers and acres infested in 2010. Even more acres were infested in 2011. 

Grasshopper counts as high as 30/sq. yard were common and there was considerable crop loss. We had 

more grasshoppers than usual on rangeland, but few acres met treatment thresholds. So, we are more or less 

the reverse on most eastern Wyoming counties where rangeland grasshoppers were the issue. 

 

It was interesting to notice how heavily infested fields in 2010 had fewer hoppers in 2011, and areas of the 

county with moderate numbers in 2010 had many more in 2011. It looks like a single year peak. However, 

less than half of the crop land in Fremont County has had heavy infestations to date, and that certainly 

suggests that 2012 could be as bad as prior years. Dimilin has both a residual effect and a lower cost for both 

chemical and application than most of the other cropland insecticides available for grasshopper control. I 

thought that I had heard talk about an expansion of the Section 3 label to include alfalfa. If that is actually 

happening, then we will have Dimilin to work with, but if not, then a Section 18 for 2012 would be most 

welcome. I hope there is enough support in the state to justify the effort.

Thank you Lars! 

 

I'm waiting for a reply back from EPA then I'll get the ball rolling. Dimilin is on their Quick List for recertification so the wait time shouldn't be too long. 

 

Have a wonderful weekend!

Dear Ms Cross; 

 

Uinta County may be faced with grasshoppers this year. Little moisture and an open winter could constitute 

the need to spray a few hot spot areas. One area is an alfalfa pivot surrounded by range land and historically 

has had high numbers of grasshoppers. I spoke with the landowner and he said toward the end of the 

season he noticed the number of grasshoppers increasing. Last year he had enough irrigation water to keep 

them out of his fields until harvest so he was not worried about spraying. 

 

Throughout the county toward the fall I noticed more grasshoppers around hayfields. The continuation of little 

moisture this spring could cause them to increase in numbers and problem areas. I realize Uinta County 

does not historically have high treatment areas but it would be a valuable treatment option if needed. 

 

Sincerely,

Dear Ms. Cross, 

 

We would like the Wyoming Department of Agriculture to seek a section 18 label for Dimilin 2L to use on 

forage alfalfa. The majority of our aerial treatment areas for grasshoppers are in cultivated fields. There is a 

mosaic of small grains, pasture and non-crop areas mixed with forage alfalfa fields. Treatment costs increase 

in areas of patchwork application. Efficacy is also reduced when adjacent fields are skipped for labeling or 

other restrictions. In 2011, we treated nearly 40,000 cultivated areas with fix winged aircraft, having an alfalfa 

forage label increased the effectiveness of the treatments and reduced the cost of application. 

 

Thank you,

May be used in a RAATs (Reduced Area and Agent Treatment) application on early instars. A RAATs application is an IPM strategy that takes advantage of grasshopper movement and conservation biological control to allow Dimilin 2L to be applied on a reduced 

treated area and at reduced rates, while sustaining acceptable control. 

The rate range to use per acre and amount of area treated will depend on grasshopper/ 

Mormon cricket age, plant canopy and topography. Skip up to 50% of the infested area 

(every other swath) and use the lower rate under uniform topography with early instar 

ages and sparse vegetation. If the majority of the population is late instars, vegetation 

is dense, terrain is considered rough, and conditions are hot during treatment, then the 

coverage and rate of DIMILIN 2L should be increased up to a blanket (100%) coverage 

with 1 fl oz per acre.

Applications may be made after each cutting of alfalfa. Do not apply more than three 

applications per year.

DIMILIN will not effectively control grasshoppers and Mormon crickets once they reach the adult stage

Aerial application: For low/high volume application, apply in 2 to 10 gallons of water per acre. For ULV application, apply in a minimum of 12 fl. ozs. 

total volume per acre.

Ground application: For low/high volume application, apply in 2 to 30 gallons of water per acre. For ULV application, apply in a minimum of 12 fl. ozs. 

total volume per acre.

Regardless of application type, total spray volume used must ensure thorough coverage of the target crop. Aerial and ULV spray mixtures should 

include an evaporation/drift retardant product at use rates prescribed on the specific product label, particularly when conditions are favorable for 

water evaporation (e.g., high air temperature and/or low humidity). When using oil type evaporation/drift retardant products, be sure to maintain a 

ratio of at least 2 parts water to 1 part oil.

For low volume and ULV applications, make sure that the spray mixture in the boom contains the correct concentration of Dimilin 2L before application begins, and be sure that good agitation is maintained throughout mixing and application.

SPRAY DRIFT LABELING

This product may contaminate water through drift of spray in wind. This

product has a potential for runoff for several months or more after application. Poorly draining soils and soils with shallow water tables are

more prone to produce runoff that contains this product. A level, well

maintained vegetative buffer strip between areas to which this product is

applied and surface water features such as ponds,streams,and springs will

reducethepotentialforcontaminationofwaterfromrainfall-runoff.Runoff

of this product will be reduced by avoiding applications when rainfall is

forecasted to occur within 48 hours. Sound erosion control practices will

reducethisproduct'scontributiontosurfacewatercontamination.Avoiding

spray drift at the application site is the responsibility of the applicator.The

interaction of many equipment-and-weather-related factors determine

the potential for spray drift. The applicator is responsible for considering

all these factors when making decisions.The following drift management

requirements must be followed to avoid off-target drift movement from

aerial applications to agricultural field crops. These requirements do not

apply to ULV applications on grassland and non-crop areas,for the control

of grasshoppers and Mormon crickets.

The distance of the outer most nozzles on the boom must not exceed

3/4 the length of the wingspan or rotor.

Where states have more stringent regulations, they should be observed.

The applicator should be familiar with and take into account

the information covered in the Aerial Drift Reduction Advisory

Information

Information on Droplet Size

The most effective way to reduce drift potential is to apply large droplets.

The best drift management strategy is to apply the largest droplets that

provide sufficient coverage and control. Applying larger droplets reduces

driftpotential,butwillnotpreventdriftifapplicationsaremadeimproperly,

or under unfavorable environmental conditions (see Wind, Temperature

and Humidity, and Temperature Inversions).

Controlling Droplet Size

Volume - Use high flow rate nozzles to apply the highest practical spray

volume. Nozzles with higher rated flows produce larger droplets.

• Pressure - Do not exceed the nozzle manufacture's recommended

pressures. For many nozzle types lower pressure produces larger

droplets. When higher flow rates are needed, use higher flow rate

nozzles instead of increasing pressure.

• Number of nozzles - Use the minimum number of nozzles that provide

uniform coverage.

• Nozzle Orientation - Orienting nozzles so that the spray is released

parallel to the airstream produces larger droplets than other orientations and is the recommended practice. Significant deflection from

the horizontal will reduce droplet size and increase drift potential.

• Nozzle Type - Use a nozzle type that is designed for the intended

application. With most nozzle types, narrower spray angles produce

larger droplets. Consider using low-drift nozzles. Solid steam nozzles

oriented straight back produce the largest droplets and the lowest

drift.

Boom Length

For some use patterns, reducing the effective boom length to less than

3/4 of the wingspan or rotor length may further reduce drift without

reducing swath width.

Application Height

Applications should not be made at a height greater than 10 feet above

the largest plants unless a greater height is required for aircraft safety.

Making applications at the lowest height that is safe reduces exposure of

droplets to evaporation and wind.

Swath Adjustment

When applications are made with a cross-wind,the swath will be displaced

downwind. Therefore, on the up and downwind edges of the field, the

applicator must compensate for the displacement by adjusting the path

of the aircraft upwind. Swath adjustment distance should increase, with

increasing drift potential (higher wind, smaller drops, etc.)

Wind

Drift potential is lowest between wind speed of 2-10 mph.However,many

factors,includingdropletsizeandequipmenttypedeterminedriftpotential

at any given speed. Application should be avoided below 2 mph due to

variable wind direction and high inversion potential. NOTE: Local terrain

can influence wind patterns.Every applicator should be familiar with local

wind patterns and how they affect drift.

Temperature and Humidity

When making applications in low relative humidity, set up equipment to

produce larger droplets to compensate for evaporation.Droplet evaporation is most severe when conditions are hot and dry.

Temperature Inversions

Applications should not occur during a temperature inversion because

drift potential is high. Temperature inversions restrict vertical air mixing,

which causes small suspended droplets to remain in a concentrated cloud.

This cloud can move in unpredictable directions due to the light variable

windscommonduringinversions.Temperatureinversionsarecharacterized

by increasing temperatures with altitude and are common on nights with

limited cloud cover light to no wind.They begin to form as the sun sets and

oftencontinueintothemorning.Theirpresencecanbeindicatedbyground

fog; however, if fog is not present, inversions can also be identified by the

movement of smoke from a ground source or an aircraft smoke generator.

Smoke that layers and moves laterally in a concentrated cloud (under low

wind conditions) indicates an inversion,while smoke that moves upwards

and rapidly dissipates indicates good vertical air mixing.

Sensitive Areas

The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g. residential areas, bodies of water, known habitat 

for threatened or endangered species, non-target crops) is minimal (e.g.

when wind is blowing away from the sensitive areas).

INFORMATION

DIMILIN 2L is an insect growth regulator which is effective on a wide

variety of insect pests, predominately from the families Lepidoptera and

Diptera. Because of its mode of action, which results in a disruption of

the normal molting process of the insect larvae, the action of DIMILIN is

slow and several days may elapse before the full effect is seen. Because

of its specificity, DIMILIN haslittle or no effect on bees or other beneficial

insects and is therefore an excellent product for use in IPM programs.

RESISTANCE MANAGEMENT:When used as directed DIMILIN 2L provides

control of a number of important insect pests as well as providing a margin

of safety to beneficial insects and pollinators.DIMILIN 2L should be part of

an IPM program that follows good management practices that include:

– Scouting regularly and use DIMILIN 2L against early immature

stages for best results

– Always follow the label rate and timing directions

– Use chemical alternatives such as oil and preserve beneficial

arthropods as part of an IPM program

– Maintain good coverage of all leaf surfaces with adequate water

volume

– Alternate treatments to classes of insecticides with different

modes of action

RESTRICTIONS

Do not apply this product to bodies of water where swimming is likely

to occur.

For Field Crops, Row Crops, Orchard Uses, Grassland and Non-Crop

Areas:Do not apply within 25 feet by ground or 150 feet by air of bodies

of water such as lakes,reservoirs,rivers,permanent streams,natural ponds,

marshes or estuaries. All applications must include a 25 foot vegetative

buffer strip within the buffer zone to decrease runoff.

RESTRICTIONS ON ROTATIONAL CROPS:Do not plant food or feed crops

in DIMILIN treated soils within 1 month following last application, unless

DIMILIN is authorized for use on these crops.

APPLICATION INSTRUCTIONS

USE AND MIXING DIRECTIONS IF USED WITH WATER:

1. Fill tank with half of the required amount of water.

2. Begin agitation and add required amount of DIMILIN 2L.

3. Continue agitation while adding remainder of water.

4. If permitted for the use site, add proper quantity of oil slowly.

To avoid formation of an invert emulsion, use at least 2 parts of

water for each part of oil.

USE AND MIXING DIRECTIONS IF USED WITHOUT WATER:

Alwaysevaluate any potentialmixturefor compatibility andsprayability.To

ensure thorough mixing of DIMILIN 2L with insecticides or other carriers,

it is recommended that ingredients be premixed in a nurse tank prior to

being transferred to aerial or ground ULV application equipment. If nurse

tank is not available, or unable to simultaneously mix:

1. Fill tank with the required amount of oil and/or oil based

insecticide.

2. Begin agitation and add required amount of DIMILIN 2L.

3. After the contents of the tank have been thoroughly agi 

tated, a volume of carrier sufficient to fill the booms and

piping system should be drained and then added back to

the tank.

Aerial or ground application: Spray should be applied with aerial or

ground equipment designed or modified to insure full uniform coverage

of the entire plant. Adjust equipment to provide droplets with a diameter

of 150 to 220 microns. Provide agitation prior to, during, and after blending and while applying.
Application Rate

Crops Pests (fl oz/acre) Application Timing

Barley BARLEY, OATS, TRITICALE & WHEAT RESTRICTIONS:Do not make more than 1 application per season. Do not exceed 4 fl oz per 

Oats acre. Do not apply after boot stage of growth. For Use in The Following States Only: Alaska, Colorado, Idaho, Montana, Nevada,

Triticale Oregon, Utah, Washington, Wyoming, Western North & South Dakota and Western Nebraska (West of Route 281 in ND, SD & NE)

Wheat Pre-harvest Interval: Do not harvest grain and straw within 50 days of application. Do not harvest forage within three days of

application. Do not harvest hay within 15 days of application.

Grasshopper 1 - 2 For best results, apply when the majority of infesting grasshoppers have reached the 2nd

to 3rd nymphal stage of development. DIMILIN 2L is not effective in controlling

grasshoppers once they reach the adult stage. If a large influx from neighboring fields

should occur, the time to reduce that population may not be short enough to

minimize extensive foliage feeding; a tank mix with a knockdown insecticide is

recommended under these conditions.

Cereal leaf beetle 4 For best results, apply at first sign of egg laying. Do not apply if infestation has advanced

into later instar larvae.

Aerial Application: Apply in 2 to 5 gallons total volume per acre.

Ground Application: Apply in 5 to 15 gallons of total volume per acre. Use sufficient application volume to assure adequate

coverage. Because of the unique mode of action of DIMILIN, its visible effects on larvae and nymphs may not be seen until 5 to 7 days

following application.

Cotton COTTON RESTRICTIONS:Do not exceed 6 applications per season. Do not exceed 24 fl oz per acre. Do not exceed 3 applications and 12

fl oz post boll opening. Pre-harvest Interval:Do not harvest within 14 days of application.

Beet armyworm 2 - 4 For early infestations on young cotton, DIMILIN 2L should be applied at the first sign of 

 -early season beet armyworm activity (2 egg masses or hatch outs/100 feet of row) in multiple applica 

before first bloom tions, either as directed or broadcast spray. Use on a 5 to 7 day interval until 8 fl oz per acre

have been applied. Multiple applications of DIMILIN 2L will provide acceptable beet armyworm control and because it has little activity on beneficial insects (parasites and preda

tors) and has good persistence, will help prevent populations of beet armyworm from

building up later in the growing season. Use of DIMILIN 2L in this way allows for more

complete coverage of new foliage during the period of rapid vegetative growth.

Beet armyworm 4 - 8 Apply starting around first bloom and through mid-bloom. Repeat application until up to

 - mid season 8 fl oz per acre have been applied, using a 5 to 7 day interval between applications.The

higher application rate should be used on larger cotton and/or under conditions of greater

larval pressure. First application should coincide with peak beet armyworm moth catches

in pheromone traps, indicating another generation of larvae is imminent. DIMILIN is more

effective on early stages of larval development, therefore cotton leaves should be treated

before populations become established.

Beet armyworm 6 - 8 Apply after mid-bloom and prior to 14 days before harvest.The higher application rate

 - late season should be used on larger cotton and/or under conditions of greater larval pressure.

Application should coincide with peak beet armyworm moth catches in pheromone traps.

Additional applications may be needed if larval pressure continues.

Fall armyworm 4-8 Application should be made during early stages of larval development. Repeat application

Boll weevil - early season 4 - 8 DIMILIN 2L will control boll weevil by suppressing reproduction. Apply with 2 to 4 qt of

(before first bloom) emulsified cottonseed oil, vegetable oil, or paraffinic crop oil. For ULV application, use 4 fl

oz in a minimum of 8 fl oz of emulsified cottonseed oil, oil based insecticide, or vegetable

or petroleum based oil carrier. A compatibility agent may be needed if a non-emulsified

cotton-seed oil is used. Consult your supplier or Chemtura representative for oil specifica

tions. For best suppression of boll weevil reproduction, make first application at pinhead

square stage of cotton growth when overwintering boll weevils are entering the fields.

Repeat applications should allow a minimum of 7 days between applications.

DIMILIN does not kill the adult boll weevil, however, eggs deposited by affected female

weevils will not hatch, thus limiting reproduction.The control of egg hatch and larval

development within the square prevents its shedding and will then allow normal boll

development. After the initial treatment of the female weevil, 7 to 10 days are required

before non-hatching eggs are laid; however, once affected, non-hatching eggs will be laid

for approximately 10 days, and longer if the female encounters more DIMILIN.Thus treat

early and use multiple applications.

Boll weevil 2 - 4 DIMILIN will reduce the number of weevils that emerge in the following spring if applica 

 - late season tions are made when adult weevils are going into diapuase to overwinter. Apply when

cotton plant has reached full vegetative growth or when it begins blooming out the top.

For LV application spray in combination with 2 to 4 qt of an emulsifiable vegetable or paraf

finic oil per acre. For ULV application combine in a minimum of 8 oz of emulsified cottonseed

oil, oil based insecticide, or vegetable or petroleum based oil carrier. A compatibility agent

may be needed if a non-emulsified cottonseed oil is used. At least 2, but not more than 3,

applications at 7 to 14 day intervals should be made.

When DIMILIN is used alone for boll weevil control, it allows normal build-up of beneficial insects that may aid control of bollworm and

budworm. Emulsifiable concentrate insecticide formulations used in tank mixes, in the presence of oil, may result in phytotoxicity. Care

should be taken where such mixtures are used.

Crops Pests (fl oz/acre) Application Timing

Cotton Grasshopper 2 Apply when the majority of infesting grasshoppers have reached the 2nd to 3rd nymphal

 (cont.) stage of development. DIMILIN is not effective in controlling grasshoppers once they

reach the adult stage.If a large influx from neighboring fields should occur,the time to reduce

that population may not be short enough to minimize extensive foliage feeding; a tank mix

with a knockdown insecticide is recommended under these conditions.

Aerial application: Apply in 3 to 5 gallons total volume per acre. For ULV application, use a total volume of 20 to 48 oz per acre.

Ground application: Apply in 10 to 20 gallons of total volume per acre. For ULV application, use a total of 20 to 64 oz per acre.

Adjuvant usage: Always use oil (1 to 2 qt) with DIMILIN 2L for larval/nymphal control if conditions are favorable for water evaporation

(e.g. high air temperature and/or low humidity). For ground or aerial LV application, 1 pt to 2 qt of emulsified vegetable or paraffinic

crop oil is recommended to enhance canopy penetration and to reduce spray droplet evaporation and subsequent drift. For ULV

application, use DIMILIN 2L in a minimum of 20 oz of emulsified cottonseed, vegetable or petroleum based oil carrier. A compatibility

agent may be needed if non-emulsified cottonseed oil is used.

Consult your supplier or Chemtura representative for oil specifications.

Use sufficient application volume to assure adequate coverage. DIMILIN 2L may be mixed with other insecticides being applied for

other cotton insects.When emulsifiable concentrate insecticide formulations are used with oil and DIMILIN in tank mixes, they may

result in phytotoxicity. Care should be taken where such mixture is used.

Because of the unique mode of action of DIMILIN, its visible effects on larvae/nymphs may not be seen for 5 to 7 days following

application.

RESTRICTIONS: Do not apply to livestock. Do not contaminate feed or water through application.

House fly 5 fl. ozs./ Apply as a directed spray in spot treatments at a volume of 1 quart of spray solution to

Stable fly 10 gals. water 10 sq. ft. of surface area. 100 gallons of spray solution will treat 4000 sq. ft.

Face fly Begin applications when flies first appear. Repeat applications should be made as

Horn fly needed when adult fly numbers begin to increase, typically at 2-3 week intervals.

Dimilin 2L will not control fly adults or pupae, but does provide extended control of the

developing larvae. If a large adult fly population already exists, application of a knock

down insecticide may be desirable to achieve rapid reduction of the adult population.

Livestock operations includes feedlots, dairies, farms, barns, farm buildings, and equine facilities. Application sites within these 

operations include wall footings, fence lines of holding pens, feed bunks, hay bale feeders; and marginal areas of waste retention ponds.

For optimum control around hay feeding sites, be sure to treat the entire area where manure and waste hay are mixed at the

soil surface by livestock activity.

GRASSLAND RESTRICTIONS: Do not exceed a total of 2 fl oz per acre per cutting. Do not exceed a total of 6 fl. oz. per acre per

year. Allow at least 1 day after treatment before cutting grass. Apply only when the potential for drift to adjacent sensitive areas

(e.g. residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal

(e.g. when wind is blowing away from the sensitive areas).-

Grasshopper 1 - 2 Use 1 application on early instar (majority in the 2nd through 4th instar nymphal stages);

use high rate for pastureland.

Mormon cricket 0.75 - 1 Use on rangeland only, in a RAATs (Reduced Area and Agent Treatment) application on

early instars. A RAATs application is an IPM strategy that takes advantage of grasshopper

movement and conservation biological ,control to allow DIMILIN 2L to be applied on

rangeland on a reduced treated area and at reduced rates, while sustaining acceptable

control. RAATs may provide ranchers with an economic means to reduce competition

by these insects on their rangeland, depending on insect age and plant canopy.

Using this program DIMILIN 2L may be applied on as little as 50% of the infested acreage

(e.g. skipping a 100 ft swath for every 100 ft treated), up to 100% infested acreage.

The rate range to use per acre and amount of area treated will depend on grasshopper/

Mormon cricket age, plant canopy and topography. Skip up to 50% of the infested area

and use the lower rate under uniform topography with early instar ages and sparse vegetation. If the majority of the population is late instars, vegetation is dense, terrain is

considered rough, and conditions are hot during treatment, then the coverage and rate

of DIMILIN 2L should be increased up to a blanket (100%) coverage with 1 fl oz per acre.

0.5 - 1 If a second application is made, typically apply 2 to 3 weeks after the first application.

Lepidopteran foliage 2 For maximum control use DIMILIN 2L at first sign of hatch outs and prior to larvae

feeding caterpillars reaching fourth instars (<1/2 inch). DIMILIN 2L must be ingested and larvae must molt

such as: before populations are reduced.

Fall armyworm

Striped grass looper

Horn Fly 2 Apply Dimilin 2L for the control of Horn fly and face fly emergence from cattle manure

Face fly patties for two weeks or longer.

Aerial application: For low/high volume application, apply in 2 to 10 gallons of water per acre. For rangeland ULV application,

apply in a minimum of 12 fl. ozs. total volume per acre.

Ground application: For low/high volume application, apply in 2 to 30 gallons of water per acre. For rangeland ULV application,

apply in a minimum of 12 fl. ozs. total volume per acre.

Regardless of application type, total spray volume used must ensure thorough coverage of the target crop. Aerial and ULV

spray mixtures should include an evaporation/drift retardant product at use rates prescribed on the specific product

label, particularly when conditions are favorable for water evaporation (e.g., high air temperature and/or low humidity).

When using oil type evaporation/drift retardant products, be sure to maintain a ratio of at least 2 parts water to 1 part oil.

For low volume and ULV applications, make sure that the spray mixture in the boom contains the correct concentration of Dimilin

2L before application begins, and be sure that good agitation is maintained throughout mixing and application. 

Higher rates and gallonages are suggested for areas with dense vegetation,when nymphs are beyond the 3rd instar stage,and when

climatic conditions are favorable for grasshopper/Mormon cricket survival and increase.

Apply anytime after eggs begin to hatch through early instars. DIMILIN 2L remains active on the foliage and will continue to

control larvae and grasshoppers/Mormon crickets that hatch later in the season. DIMILIN 2L is not effective in controlling larvae

and grasshoppers/Mormon crickets once they have reached the adult stage. Since it is an insect growth regulator, effects may not

be seen until these insects have molted at least once. If adult grasshoppers/Mormon crickets from early hatching and/or overwintering species are present, tank-mix DIMILIN 2L with a registered adulticide to control later hatching species.

Check mixing compatibility and sprayability prior to transferring to the main spray tank.

Besides a fatal incomplete molting, adult grasshoppers/Mormon crickets may exhibit missing posterior legs, hernias, abdominal 

segments malformed, twisted antennae, hemolymph exudation, and wrinkled wings. Additionally, they may move slower, have

limited jumps and unsteady landings, show a reduction in feeding, have atrophy of posterior legs or be unable to fly. Any nymph/

adult possessing these symptoms is likely more susceptible to predatory insects, birds and mammals.

DIMILIN has been shown not to impact adult populations of various ground dwelling and flying non-target arthropods in a

rangeland ecosystem.

Apply when oviposition begins on new growth flush. Use sufficient spray volume for thorough coverage of leaf surfaces (ground = 50 to 1,000 gallons per

acre; aerial = 5 to 20 gallons per acre). Repeat application no closer than 90 days

apart for subsequent leaf flushes. The addition of a spray oil, such as FC435-66,

enhances coverage and may enhance control of citrus leafminers. Dimilin 2L

will not kill adult stages of leafminers. Dimilin 2L has activity on eggs, larval and

pupal stages.

Apply when oviposition begins on peel surface. Use sufficient spray volume for

thorough coverage of leaf surfaces (ground = 50 to 1,000 gallons per acre; aerial

= 5 to 20 gallons per acre).The addition of a spray oil,such as FC435-66,enhances

coverage and may enhance control of peelminers.Dimilin 2L prevents development of peelminer eggs laid on protected fruit tissues. Protection may last only

a few weeks when new tissue is exposed on rapidly expanding fruit.

Apply Dimilin 2L to newly expanded flush on citrus and/or when adult weevils

are present. Use sufficient spray volume for thorough coverage of leaf surfaces

application no closer than 90 days apart for subsequent leaf flushes and/or when

adult weevils are present.The addition of a spray oil,such as FC435-66,enhances

coverage and penetration of Dimilin 2L into the adult weevils and eggs. Also oil

will deter attachment of weevil egg masses to leaf surfaces

Dimilin 2L will not kill adult weevils.The activity of Dimilin 2L is through ingestion

or contact and will result in reduction of the reproductive potential of weevils,

it prevents eggs from hatching, thus preventing larvae from entering soil and

feeding on citrus tree roots. Also, the grubs from eggs laid on treated leaves are

reduced in number.

Pear PEAR RESTRICTIONS: Do not apply more than 4 applications per year. Do not apply more than 64 fl oz per acre per year.

Pre-harvest Interval: Do not harvest within 14 days of application. Do not use oil in tank mix in late season treatments (3rd and

4th applications).

Pear psylla (pre-bloom) 40 - 48 Apply in 80 to 400 gallons of water per acre during the delayed dormant to the pop

corn stage period.

Complete uniform coverage of the tree is essential to achieve optimum control. A

horticultural mineral oil should be used at a rate of 4 to 6 gallons per acre during the

delayed dormant period. After this period and through the popcorn stage, apply oil at

a concentration of 0.25%, but use no more than 1 gallon per acre. A surfactant

may be used to improve coverage. Follow manufacturer’s label recommendations.

DIMILIN 2L should be applied during egg deposition so that it will come in contact with

pear psylla eggs and/or 1st and 2nd instar nymphs.

Pear psylla (post-bloom) 12 - 16 Applications at normal codling moth rates and timings will provide suppression of

pear psylla.

Pear rust mite 40 - 48 Apply in 80 to 400 gallons of water per acre from delayed dormant to the popcorn

(pre-bloom) stage. See ‘Pear psylla (pre-bloom)' for the use of oil.

Codling moth 12 - 16 Apply in a minimum of 80 gallons of water per acre. Use the lower rate where there is

light codling moth pressure and/or on small trees. Complete coverage of the fruit and

foliage in all areas of the trees is essential for optimum control. Timing of application

is extremely important because DIMILIN 2L controls codling moth by prohibiting

the hatching of eggs. It must be applied prior to egg laying so that eggs are laid on

treated plant parts.

First application should be made as soon as possible after first moths are caught (bio

fix) or observed,or about 50-75 degree-days after biofix.This timing can be determined

by your local pest control consultant and/or fruit specialist with the aid of pheromone

traps. Normally this timing occurs at late petal fall or about 10-14 days earlier than the timing used for organophosphate insecticides.

Second application should be made about 14-18 days after the first.

Third and fourth application, if necessary, should be timed prior to egg laying of the

2nd generation by using the same method as for the 1st generation. If traps are not

used,make the 3rd application 21-30 days after the second,followed by the 4th application 21-30 days later. If a degree-day model is used the 3rd spray should be timed at

1000 degree-days after biofix.

Combination with organophosphates for codling moth control: DIMILIN 2L can be

used in combination with an organophosphate insecticide, to save a trip through the

orchard and to make timing of the DIMILIN 2L sprays easier. The combination is more

effective than DIMILIN 2L alone when controlling moderate to heavy codling moth

infestations and/or treating large trees.The combination will provide residual control

of eggs laid after application. Apply DIMILIN 2L and the organophosphates at their

labeled rates. Apply at the beginning of egg hatch of 1st generation codling moth.This

is the normal timing for the first organophosphate cover spray (250 degree-days

following biofix for 1st generation and 1250 degree days for the 2nd generation). This

program can be repeated for the 2nd or 3rd generation of codling moth or use DIMILIN

2L alone prior to egg laying. Do not use oil in tank mix with DIMILIN 2L in late season

treatments.

With light codling moth populations, as indicated by monitoring, this combination

may offer control of an entire generation with 1 application. When populations are

heavy, this combination will improve control,but it may not control an entire generation

with one spray. A second spray of DIMILIN 2L alone or in combination may be applied

14-18 days later.

Leafminer 8 - 16 Apply in a minimum of 80 gallons of water just prior or during egg laying to control

eggs and larvae.Timing for control of the 1st or 2nd generation can be determined by

your local pest control consultant or fruit specialist.Should later generations of leafminers occur, DIMILIN 2L should be applied in the same manner.

It is desirable to have DIMILIN 2L in place at the time of egg laying. It will continue to

give control through the early sap feeding stage. Complete coverage of the foliage is

essential to achieve control of the larvae through the early sap feeding stage.

Oil may cause injury to certain pear varieties. Check compatibility of oil mixtures with your local tree fruit specialist.

Pepper PEPPER RESTRICTIONS:Up to five applications per growing season may be made as long as 24 fl oz. per acre, per season are not

Bell and exceeded. Allow a minimum of seven days between any two applications. Do not apply within seven days of harvest.

 Non Bell Do not apply more than 24 fl oz. per acre per season.

Beet armyworm 4 - 8 Make initial application of 4 to 8 fl oz. Dimilin 2L per acre when larvae are small to give

Fall armyworm greater control and minimum damage to leaves and/or to fruit. Use a higher rate if

Southern armyworm being applied alone and/or infestation is considered heavy. A knockdown tank-mix

and other foliage partner should be used if late instar larvae are present. Use a minimum of 30 gallons

feeding Lepidopteran of water per acre to give uniform coverage. Additional applications allow for more

insects complete coverage of new foliage and expanding fruit.

Pepper weevil 4 - 8 Apply Dimilin 2L at 4 to 8 fl oz. per acre starting at initial flowering. Use at the higher

rate if adult infestation is considered moderate to heavy. Apply additional applications

at 7 day intervals up to 7 days before harvest. Additional applications allow for more

complete coverage of new foliage and expanding fruit. Note that Dimilin will not

control adults; however eggs laid by adults will exhibit reduced hatching in fruits once

adults have consumed or contacted residues of Dimilin on pepper tissue.

Aerial application: Apply in sufficient water (3 to 10 gallons per acre) to achieve uniform coverage of foliage.

Ground application: Use a minimum of 30 gallons of water per acre to give uniform coverage.

Adjuvant Usage: See Cotton Section.

Since DIMILIN is an insect growth regulator, larvae and nymphs must ingest treated plant material and then molt before populations

are reduced.Thus initial signs of control may not be seen until 5 to 7 days after treatment.

Rice RICE RESTRICTIONS: Pre-harvest Interval: Do not harvest within 80 days of application. Do not use on rice fields in which crayfish

(crawfish) farming is included in the cultural practice. Do not drain treated water into fields where crayfish farming is intended Do not

apply to rice immediately adjacent to sites of crayfish aquaculture. Do not use treated rice flood waters for irrigated crops except for

uses currently established for DIMILIN. Do not impregnate on granular materials. Do not use on wild rice (Zizania spp.).

Rice water weevil 12 - 16 Make a single application of DIMILIN 2L per acre per year to control larvae when adult

(Southern U.S.Rice Belt) infestations reach economic threshold and/or at initial oviposition, usually within a time

-for drill seeded; dry frame of 2-5 days after permanent flood establishment. If adult weevil infestations are

seeded; or water seeded, historically high and/or migration into the field is prolonged, use the higher application

delayed flood rice rate.

Rice water weevil 8 + 8 To control larvae, split applications should be made.. Apply 8 fl oz per acre after the

(Southern U.S. Rice Belt) permanent flood when adult infestations reach economic threshold and/or at initial

water seeded, pinpoint oviposition, usually when rice leaves are exposed above the water surface.The 2nd 8 fl

flood, or continuous oz treatment must be made 5-7 days after the 1st application. Failure to make

flood rice the second application within the above timeframe could result in inadequate control

of rice water weevil larvae, especially if adult infestations are high and/or migration into

the field is prolonged.

Rice water weevil 8 - 16 To control larvae apply DIMILIN 2L once per year at initiation of oviposition by adults.

(California) During a typical year this coincides with 2 to 8 days after rice emergence above the

water. For best results target the application for 2 to 5 days after rice emergence above

the water (2 to 4 leaf stage). Use 12 to 16 fl oz DIMILIN 2L if infestations have been

historically high.

Consult your local extension service for determination of economic threshold and/or determination of oviposition.

DIMILIN does not appear to control adult weevils. It controls rice water weevil by preventing larval emergence from the egg. Eggs laid

under the surface of treated water are controlled. Additionally, adults feeding on treated plant surfaces do not lay viable eggs.

Apply DIMILIN 2L by air using at least 5 gallons total volume per acre.

Do not apply DIMILIN 2L if flooding is in progress. Activity will be reduced. Since DIMILIN 2L is water active, the entire field should be

treated.

For maximum activity of DIMILIN 2L do not disturb flood after a single application for at least 7 days.With split applications in water

seeded, pinpoint or continuous flood rice, flood should not be disturbed for a minimum of 4 day following the 1st treatment and 7

days following the 2nd application.Treated water should be held at least 14 days to allow for dissipation of DIMILIN 2L.

DIMILIN 2L is not phytotoxic to rice. DIMILIN 2L can be safely applied in combination with post permanent flood herbicides such as

FACET®, GRANDSTAND® and LONDAX®. However, before using a tank-mix combination, read each product label carefully and follow

Precautionary Statements on each label.

once they reach the adult stage. If a large influx from neighboring fields should

occur, the time to reduce that population may not be short enough to minimize

extensive foliage feeding; a tank mix with a knockdown insecticide is recommended

Aerial application: apply in sufficient water (3 to 5 gallons per acre) to achieve uniform coverage of foliage.

Ground application: apply in 9 to 35 gallons of water per acre to give uniform coverage.

Adjuvant usage: See Cotton Section.

Since DIMILIN is an insect growth regulator, larvae/nymphs must feed on it and then molt before populations are reduced. Thus

initial signs of control may not be seen until several days after treatment.

Soybean yield enhancement: In the absence of significant insect pressure and under certain growing conditions, an increase

in soybean seed yield has been demonstrated with DIMILIN under field conditions on both determinate and indeterminate

cultivars. Application of 2 to 4 fl oz per acre to high yield potential soybean plants at the R3 to R3.5 growth stage period has been

more consistent in increasing yields than applications at other reproductive stages of the soybean plant. This reproductive period

represents beginning pod growth (pod 3/16 inch long at one of the uppermost nodes on the main stem with a fully developed leaf )

to just prior to full pod elongation (pod 3/4 inch long at one of the 4 uppermost nodes on the main stem with a fully developed leaf ).

STONEFRUIT RESTRICTIONS: Do not apply after petal fall. Do not exceed 2 applications in any given season. Do not exceed 0.50

lb ai (32 fl oz) per acre in any given season. Allow at least 21 days between applications.

Peach twig borer 12 - 16 Dormant/delayed dormant: Apply DIMILIN 2L with 4 to 6 gallons per acre (1.5 to

2.0 gallons per 100 gallons in a dilute spray) narrow range oil. Always use the higher

rate of DIMILIN 2L if the crop has a history of heavy infestations.

Bloom: Apply starting at early bloom. Vegetable oil may be used at the rate of 1 qt

per acre. Always use the higher rate in the range if the crop has a history of heavy

infestations.

Fall webworm 8 - 16 Apply DIMILIN at first sign of larval infestation. Use the higher rate for longer residual

Filbert leafroller control, higher pest infestations, low crop load, larger trees or heavy, dense foliage.

Ground applications should be made in sufficient water for thorough coverage, using at least 50 gallons per acre for small trees

(10 feet tall) and at least 100 gallons per acre for larger trees. Using insufficient water for thorough coverage and/or using an un

even spray pattern across the canopy will likely result in less than desired efficacy.

TREE NUT RESTRICTIONS: Pre-harvest Interval: Do not harvest within 28 days of application. Do not exceed 4 (3 for walnuts)

applications. Do not exceed 64 fl. oz. per acre per growing season.

Codling moth 16 DIMILIN is most effective when applied prior to egg laying. DIMILIN 2L must be

present on the surface upon which eggs are laid;therefore,full coverage spray is necessary. First application should be made when moth flights begin or when moths are

found in pheromone traps.The 2nd application should be made approximately 21days

after the 1st application.For control of the 2nd brood,application should be timed prior

to egg laying, similar to 1st brood.

Because of fluctuations in temperature, the emergence and moth flights of the

over-wintering population may be extended over a long period of time. Under such

circumstances,DIMILIN 2L should be tank mixed with an organophosphate insecticide

at its lowest label rate. This tank mix should be applied at normal 1st organophosphate timing. Later in the season, if egg laying has already occurred before application

of DIMILIN 2L, it is recommended that DIMILIN 2L be tank mixed with an organophosphate as previously described.

Filbert worm 12 - 16 The lower rate may be used where filbert worm pressure is low and/or the trees are

small. The higher rate is necessary when worm pressure is moderate to high and/or

the trees are large.DIMILIN 2L should be applied 2 to 3 days after the 1st moth is caught

in pheromone detection traps. Mating takes place within several days of emergence

and egg laying begins the next day.DIMILIN 2L must be applied prior to egg deposition

on the treated foliage. Good uniform coverage of the tree is essential to achieve

optimum control of filbert worm with DIMILIN 2L.

Normally DIMILIN 2L will give season long control. If moth pressure remains high,

additional applications should be made.

Hickory shuckworm 8 - 16 Apply DIMILIN 2L starting at half-shell hardening. Make subsequent applications at

21-day intervals to shuck split, or while nuts are susceptible to hickory shuckworm

under heavy infestations. Use the higher rate under higher pest infestations, low crop

load, larger trees or heavy, dense foliage.

Application Rate

Crops Pests (fl oz/acre) Application Timing

Tree nuts group Peach twig borer 12 - 16 Dormant/delayed dormant: Apply DIMILIN 2L at the rate of 12 to 16 fl oz per acre

(cont.) with 4 to 8 gallons per acre (1.5 to 2.0 gallons per 100 gallons in a dilute spray) narrow

range oil.Always use the higher rate of DIMILIN in the rate range if the crop has a history

of heavy infestations.

Bloom: Apply DIMILIN 2L at the rate of 12 to 16 fl oz per acre starting at early bloom.

Always use the higher rate of DIMILIN in the rate range if the crop has a history of

heavy infestations.

Spring flight (“May Spray”): Using pheromone traps to determine flight activity,

apply DIMILIN 2L at the rate of 16 fl oz per acre at initial flight activity.

Summer flight: Using pheromone traps to determine flight activity, apply DIMILIN

2L at the rate of 16 fl oz per acre at initial flight activity.

Pecan nut casebearer 8 - 16 Apply DIMILIN 2L at the initiation of each adult generation to target egg hatch. Note

for the 1st generation this is approximately 8 to 15 days following the first prolonged

moth catch (biofix which is defined as the date on which the total of 5 moths are

captured in 3 pheromone traps within a 7-day period). States may have a different

recommendation for initiation of spraying; please consult authorities such as county

and university extension specialists on current recommendations. Use the higher rate

for longer residual control,higher pest infestations,low crop load,larger trees or heavy,

dense foliage.

Pecan weevil 8 - 16 Use the higher rate if weevils are attacking fruit and for higher infestations.

(suppression)

Others, including: 8 - 16 Apply DIMILIN 2L at the first sign of larval infestations. Use the higher rate for longer

Fall webworm residual control, higher pest infestations, low crop load, larger trees or heavy, dense

Filbert leafroller foliage.

Ground applications should be made in sufficient water for thorough coverage, using at least 50 gallons per acre for small trees (10

feet tall) and at least 100 to 300 gallons per acre for larger trees. Using insufficient water for thorough coverage and/or using an

uneven spray pattern across the canopy will likely result in less than desired efficacy. If 4 applications are used, application timing 

should correspond to dormant to pre-bud swell, at bloom to petal fall, at flowers/leaves/immature nut fruit formation and at hull split.
