CEREAL GRAINS - RICE - ARMYWORM, WEEVIL, STINK BUG ETC.
GENERAL DIRECTIONS FOR USE
Initial and residual control are contingent upon thorough crop coverage. Apply with ground or air equipment using sufficient water to obtain full coverage of foliage. Apply in a minimum of 2 gals./A by air or 10 gals./A by ground unless otherwise specified in the label. When foliage is dense or pest pressure is high (heavier insect or egg pressure, larger larval stages), use of higher application volumes and/or higher use-rates may improve initial and residual control.
For cutworm control, LAMBDA T may be applied before, during, or after planting. For soil incorporated applications, use higher rates for improved control.
- Apply as required by scouting. Timing and frequency of application should be based upon insect populations reaching locally-determined economic thresholds. Determine the need for repeat applications, usually at intervals of 5-7 days, by scouting.
- LAMBDA T can be safely used when propanil products are being used for weed control.
- Apply by air or by ground equipment using sufficient water to obtain full coverage of foliage. When applying by air, apply in a minimum of 2 gals of water (or a total carrier volume)/A but ensure sufficient volume is used to provide adequate coverage. In addition, adding an emulsifiable crop oil (e.g., 1 pt./A) when lower aerial application volumes are used is recommended to help improve coverage, reduce evaporation, and improve efficacy.
- For control of rice water weevil in dry seeded rice, make a foliar application as indicated by scouting for the presence of adults and/or feeding scars, usually within a time-frame of 0–5 days after permanent flood establishment. Do not exceed 10 days from starting permanent flood until insecticide application unless scouting indicates weevils have not been previously present. Adults may also be treated at later stages of rice development to reduce overwintering populations.
- For control of rice water weevil in water seeded rice, make the first foliar application after pinpoint flood as indicated by scouting for the presence of adults and/or feeding scars usually when rice has emerged 0.5 inch above the waterline. Under conditions of prolonged migration into the field, start field scouting for rice water weevil adults and/or feeding scars 3-5 days after the initial treatment and, if needed, apply a second application within 7-10 days of the first application. Adults may also be treated at later stages of rice development to reduce overwintering populations.
- California: In addition to above directions for control of rice water weevil in water seeded rice, LAMBDA T may be applied at the 1-3 leaf growth stage, with the majority at the 2 leaf growth stage. Adults are vulnerable on levees and in the water.
Larvae are vulnerable while feeding on the leaf prior to entering the soil. Monitor for adults, based upon field history and
density of population. Monitor field edges and levee areas for adults. Treat in the following manner: a) spray the inside perimeter of the field, or b) spray the entire field.
- Green bug is known to have many biotypes. LAMBDA T may only provide suppression. If satisfactory control is not achieved with the first application of LAMBDA T, a resistant biotype may be present. Use alternate chemistry for control.
- Do not release flood water within 7 days of an application.
- Do not apply more than 0.08 lb. a.i. (0.64 pts.)/A within 28 days of harvest or more than 0.04 lb. a.i. (0.32 pts.)/A within 21 days of harvest.
- Do not use treated rice fields for the aquaculture of edible fish and crustacea.
- Do not apply as an ultra-low-volume (ULV) spray.
Mexican Rice Borer, Rice Stalk Borer, Sugarcane Borer, and European Corn Borer: For control before the larvae bores into the plant stalk.
