Abstract
Abstract Cabbage was transplanted on 15 Jun at the Vegetable Crops Research Farm near Geneva, NY. Plots consisted of two 20-ft rows on 36-inch centers with 18-inch plant spacing. Treatments were replicated 4 times in an RCB design. A backpack sprayer with a one-row boom, having 3 nozzles per row with HC 12 hollow cone tips, and delivering 32.6 gal/acre at 40 psi and 2 mph, was used to apply weekly applications of each treatment. Bond sticker-spreader was applied at 0.1% v/v with all treatments. Treatments were applied on 22 Jul, 2, 10, 17, 27 Aug, and 3 Sep. Evaluations were made on 29 Jul, 9, 24 Aug, and 13 Sep, by selecting three plants per replication, removing all leaves, and counting the number of live larvae. A two-way ANOVA was used for analysis of Lepidoptera data using replicate totals for the entire season.
