Abstract
Abstract Nine insecticides were evaluated to determine their efficacy in controlling corn earworms and green cloverworms. Insecticides were applied on Aug 29 on ‘Essex’ soybean grown on the Harold Delano Farm in Richmond County near Warsaw, VA. Individual plots were 4 rows 50 ft long spaced 2.5 ft apart. A randomized block experimental design with 3 replications was utilized. Each spray concentrate was applied to the soybean foliage with a CO2 powered back-pack sprayer at 30 psi that delivered 26.5 gal of finished formulation per acre. Individual treatments were evaluated 1, 3 and 7 days after application by comparing the number of corn earworms and green cloverworms per 20 sweeps (15 inch dia net) in the treated plots to those in the untreated plots.
