Comparing an Abbott Bacillus Thumngiensis Product to Permethrin in a Full Season Program, 1992: Cabbage was transplanted on 16 Jun at the Vegetable Crops Research Farm near Geneva, NY. Plots consisted of two 10 ft rows on 36 inch centers with 18 inch plant spacing. Treatments were replicated 4 times in a randomized complete block design. A backpack sprayer with a one-row boom, having 3 nozzles per row with HC 12 hollow cone tips, and delivering 38 gal/acre at 40 psi and 2 mph, was used to apply weekly applications of each treatment. Bond sticker-spreader was applied at .01% v/v with all treatments. Treatments were applied on 27 Jul, 6, 14, 26 Aug, 11, 18 Sep. Evaluations were made on 3, 12 Aug, 9 and 28 Sep by selecting three plants per plot, removing all leaves, and counting the number of live larvae. A two-way ANOVA was used for analysis of Lepidoptera using replicate totals for the entire season.
