PEAR - CODLING MOTH
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.
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:
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.
RESTRICTIONS: Do not use oil in tank mix in late season treatments (3rd and 4th applications).
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 insect 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.
Apply first application as soon as possible after first moths are caught (biofix) 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.
Apply second application about 14-18 days after the first.
If necessary, apply third and fourth application, 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.
Oil may cause injury to certain pear varieties. Check compatibility of oil mixtures with your local tree fruit specialist.
