Chemical control is a critical component of integrated pest management in cotton and soybean production. Residual efficacy of foliar insecticides can be highly variable and difficult to quantify due to several factors. The purpose of this research was to determine residual control and concentrations in flowering structures of commonly used insecticides. This research focused on the concentrations of active ingredient within the plant as well as efficacy over time. Previous research suggested chlorantraniliprole had a long residual and was highly lethal on corn earworm up to 28 days after treatment (DAT) in soybean; however, the results found in cotton were inconclusive. From this research, concentrations of chlorantraniliprole were found in flowering structures of both soybean and cotton up to 14 DAT. Bioassays conducted from chemical concentrations suggest reduced rates of chlorantraniliprole, similar to what was found in the flowering structures, provided mortality of corn earworm up to 64%.
