![]() This product is highly toxic to bees exposed to direct treatment or residues on blooming crops or weeds. ![]() ![]() Do not exceed 0.025 lb ai/cutting and 0.075 lb ai/A per season. alpha-cypermethrin (Fastac EC) at 0.014 to 0.025 lb ai/A. ![]() Applications in late evening, when larvae usually feed above ground, are most effective. This brings larvae to the surface, making control easier. When convenient, irrigate the field before treating for redbacked or army cutworms. Redbacked cutworms overwinter as eggs and caterpillars commence feeding in late winter to early spring. Variegated cutworm has an overwinter generation similar to the army cutworm and a midsummer generation. In mild winter years, be aware of large populations that can cause significant damage in late winter and early spring. Most damage occurs as caterpillars complete their development in spring. Army cutworms, redbacked and variegated cutworms begin feeding in the fall and overwinter as half-grown larvae in grain and hay fields. Cutworms are primarily a pest of alfalfa and clovers, but they attack other legumes also. Small populations (less than one larva/sq yd) can damage new seedlings. If alfalfa fields do not "green up" in the spring, or are slow to regrow after cutting in the fall, look for cutworms. Cutworms can kill seedlings and reduce stands. ![]() They usually feed at night and by day are found under leaves or in the soil at moisture level. Pest description and crop damage Cutworms usually are dull gray, brown, or black and may be striped or spotted. Army cutworm ( Euxoa auxiliaris)-adults are called "miller moths" ![]()
