The objectives of this field trial were to evaluate the efficacy of single applications of foliar insecticides at preventing feeding damage by the western bean cutworm (WBC), an important pest of corn and dry beans that has undergone a rapid range expansion into the eastern Corn Belt during the last 18 yr. This study was conducted within the historic range of WBC, at the University of Nebraska-Lincoln’s Henry J. Stumpf International Wheat Center in Perkins County, NE (40.856851°N, −101.701335°W). An RCB design with a total of 16 treatments (including an untreated check) and four replications was used. Plots measured 20 ft (8 rows) wide × 35 ft long. The trial was planted on 5 May 2018 using a commercial 8-row planter at 32,000 seeds/acre at an approximate depth of 1.40–1.75 inches in 30-inch rows. The seeds planted were DKC62-95 (Monsanto Company, St. Louis, MO), non-Bt hybrid with RR2 herbicide tolerance. Irrigation, fertilization, and weed management inputs in plots followed standard agronomic practices for the region, with no insecticide applications other than the experimental treatments.
