Abstract
Abstract Cabbage transplants were planted on 5 Aug at the Eastern Shore Agricultural Experiment Station, Painter, VA. Each plot consisted of a single 25 ft long row bordered on each side by an untreated row. Cabbage was transplanted with 17-inch plant and 36-inch row spacing. Treatments were replicated 4 times in a randomized complete block design. Sprays were applied with a propane compressed gas backpack sprayer using 3 hollow cone nozzles per row and delivering 75 gal water per acre at 40 psi. Applications were made on 5, 12, 19, and 26 Sep, and 3 and 10 Oct. Dipel 2X (0.25 lb/acre) and ABG 6167 (0.5 pt/acre) were applied in the ABG 6101 and 6204 plots, respectively, on 5 Sep. Evaluation criteria consisted of direct counts of the number of imported cabbageworm (ICW), cabbage looper (CL), diamondback moth (DB), and cabbage web worm (CWW) on 5 randomly chosen plants per treatment. On 16 Oct, damage ratings were determined as in Greene et al. (J. of Econ. Entomol., 62 (4): 798-800). Plants with a damage rating of 3 or below were considered marketable.
