General Information


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.

Limitations, Restrictions, and Exceptions


Sorghum Grain

- Apply as required by scouting, usually at intervals of 5 or more days. Timing and frequency of applications should be based upon insect populations reaching locally-determined economic thresholds.

- Apply with ground or air equipment using sufficient water and application methods to obtain full coverage of target location. When applying by air, apply in a minimum of 2 gals. of water/A.

- For sorghum midge control, begin applications when 25% of the sorghum heads have emerged and are in tip bloom. Repeat applications at 5-day intervals if needed.

- For chinch bug control, begin applications when bugs migrate from small grains or grass weeds to small sorghum. Direct spray to the base of sorghum plants. Repeat applications at 3-5-day intervals if needed. LAMBDA T may only suppress heavy infestations and/or subsequent migrations.

- Do not apply more than 0.06 lb. a.i. (0.48 pts.)/A per season after crop emergence.

- Do not apply more than 0.02 lb. a.i. (0.16 pts.)/A per season once crop is in soft dough stage.

Target Pest:

Fall Armyworm, Yellow-striped Armyworm, Use higher rates for large larvae.

European Corn Borer, Southwestern Corn Borer, Lesser Cornstalk Borer: For control before the larva bores into the plant stalk.

Beet Armyworm, See resistance statement under General Directions for Use
