Abstract Various pesticides were applied to blister stage (R6 stage) hybrid field corn on 9 Aug, near North Platte, in westcentral NE. The treatments were applied with a CO2-charged backpack sprayer through 8001 flat fan nozzles at 206,786 Pa (30 psi), in a total volume of 196.4 liter/ha (21 gal/acre). Each treatment was applied to 3 × 10 m plots, replicated 4 times in a RCBD. Three d before the pesticide application the number of WCR beetles was counted on 2 randomly-selected plants in the middle of each plot. Three d prior to application, 3 spider mite-infested plants in each plot were marked to follow population trends on the same plants. The size of twospotted spider mite colonies was rated on the underside of 3 leaves on each of these plants, one below the ear, the ear leaf and one leaf above the ear. Ratings were made on a 0-6 scale where 0 = no mites, 1 = individual mites, 2 = small colonies, 3 = large, individual colonies, 4 = large connected colonies but not completely covering the underside of the leaf, 5 = colonies completely covering the underside of the leaf, 6 = leaf dead due to spider mite damage. These plants were also evaluated for the presence of arthropod predators. Two d following application the number of rootworm beetles was evaluated by counting all beetles on two randomly selected plants in the middle of each plot. Previously marked plants were evaluated for the size of twospotted spider mite colonies and the presence of arthropod predators at 7, 14, 21 and 44 DAT. Data were statistically analyzed with analysis of variance and an LSD test was used for mean separation.
