Abstract
Abstract Wheat was planted on 13 Nov 1993 at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot was 25 ft long by 5 ft wide and replicated 4 times in a randomized, complete block design. Sprays were applied on 2 May using a 3-nozzle flat fan boom backpack sprayer delivering 20 gal water/acre at 40 psi, when CLB pressure was at or near the treatment threshold of 1 larva/flag leaf in most plots. Numbers of CLB larvae/50 flag leaves and numbers of EGA/50 ears were counted in each plot on the dates indicated in the table. Percent defoliation was rated on 12 May on 25 randomly chosen flag leaves/plot, and the plots were harvested on 7 Jul.
