Abstract
Abstract Foliar treatments of registered and non-registered insecticides for second generation European corn borer were applied to irrigated corn plots in Dixon County, NE on 9 Aug. Liquid formulated insecticides were applied with a Hahn Hi-Boy calibrated to deliver 17 gpa at 30 psi. Granular formulated insecticides were applied with Noble granulator units mounted on the same Hahn Hi-Boy with 10 inch row banders. Twenty-four hr prior to application, 6 black headed egg masses on paper disc were pinned to the middle portion of 10 marked corn plants in each replicate. Experimental design was CBD with 4 replications. On 14 Sep, 10 marked plants per replicate were dissected from tassel to ground, examined and the number of corn borer larvae recorded.
