RICE - RICE WATER WEEVIL - DELAYED FLOOD
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.
Rice water weevil (Southern U.S.Rice Belt) -for drill seeded; dry seeded; or water seeded, delayed flood 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 fl ood 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 - DELAYED FLOOD RICE
Make a single application of DIMILIN 2L per acre per year to control larvae when adult infestations reach economic threshold and/or at initial oviposition, usually within a time frame of 2-5 days after permanent fl ood establishment. If adult weevil infestations are historically high and/or migration into the field is prolonged, use the higher application rate.
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.
