Abstract

We are developing an economic threshold for application of a foliar insecticide for soybean aphid management. We employed an experimental design that has been replicated across five states in an attempt to refine the current action threshold of 250 aphids per plant. This experimental design was expanded to address how adjusting planting date, a practice recommended for bean leaf beetle Certoma trifurcata management, may also affect soybean aphids.
