Cabbage was transplanted on 19 July at the Veg. Res. Farm, near Geneva, N.Y. Plots consisted of two 10-ft rows on 36-in. centers with plant spacing of 16 in. Treatments were replicated four times in a randomized complete block. A 2-row tractor-mounted boom, having three nozzles per row and delivering 35 gal/acre at 50 lb/in2 was used to apply a single application of each treatment. Applications were made on 30 Sept. and evaluated on 7 Oct. Evaluations were made by randomly selecting three plants per plot, cutting off all leaves, and recording larval populations.
