Abstract Various pesticides were applied to blister stage (R6 stage) field corn on 9 Aug, near North Platte, NE. The treatments were applied with a CO2-charged backpack sprayer through 8001 flat fan nozzles at 30 psi, in a total volume of 21 gal/acre. Each treatment was applied to 3 by 10 m plots and replicated 4 times in a RCB design. On the day of application, neonate ECB larvae were applied, in corn cob grit, to the axils of 3 leaves of 5 plants in each plot. Artificially infested plants were collected 40 DAT, split from root to tassel and evaluated for the presence of ECB caused cavities, the total length of ECB caused cavities and live ECB larvae. The incidence of lodged plants was determined 48 DAT on 20 consecutive plants from the middle of each of the center 2 rows of each plot. BGM infested leaves were attached to 2 plants in each plot 2 d prior to application. Seven, 14, and 28 DAT the size of spider mite colonies were rated, on a 0-6 scale, on the underside of the 4 lowest leaves of the previously infested plants. These plants were also evaluated for the presence of arthropod predators.
