Abstract

Abstract Foliar treatments of registered and non-registered insecticides for 2nd generation ECB were applied to irrigated corn plots in Dixon County, NE on 12 Aug. Liquid formulated insecticides were applied with a Hahn hi-boy calibrated to deliver 17 gal/acre 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 h 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 per treatment. Experimental design was a RCB with 4 replications. On 17 Sep, 10 marked plants per replicate were dissected from tassel to ground, examined and the number of ECB larvae recorded.
