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/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.
