General 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 has little 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


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.



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.


Always evaluate any potential mixture for compatibility and sprayability. 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 agitated, 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.

Limitations, Restrictions, and Exceptions



Do not exceed 4 fl oz per acre. Do not apply after boot stage of growth. For Use in The Following States Only: Alaska, Colorado, Idaho, Montana, Nevada, Oregon, Utah, Washington, Wyoming, Western North & South Dakota and Western Nebraska (West of Route 281 in ND, SD & NE) 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.


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 infl ux 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.

Ground Application: Apply in 5 to 15 gallons of total volume per acre. Use suffi cient 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.

Restricted Entry Interval
