Abstract

Plots were established at two locations in 2018 (ISU Northwest Research Farm and ISU Northeast Research Farm). Syngenta NK S24-K2 brand soybean was used at both locations. Seven insecticidal groups/subgroups were evaluated in 2018. Seed did not have a pesticidal seed treatment unless specifically stated. At both locations, soybean aphid peaked in August (four perplant at Northeast Research Farm and 22 perplant at Northwest Research Farm). The economic threshold was not reached at either location in 2018; however, all plots were sprayed mid-August.
