Collards were transplanted 2 Jun near Benson, NC. Treatment plots were replicated 4 times in a randomized complete block design. Plots consisted of single rows 10 ft long on 42-inch centers. White plastic mulch was used on all plots. Terraclor was used in the transplant water. Treatments were applied using a CO2 pressurized backpack sprayer with a single hollow-cone nozzle (HC 17 70°) delivering 50 gal/acre at 60 psi. Insecticide applications were made on 16, 23, 30 Jun, 7, 14 and 25 Jul. Dipel WP (0.5 lb (AI)/acre) and Sevin 80SP (1.0 lb (AI)/acre) were applied to ABG-6146 treatment plots on 16 Jun and 23 Jun, respectively. Insects were counted 16, 23 and 30 Jun, and damage was evaluated 30 Jun, 19 Jul and 8 Aug. Harlequin bug damage was evaluated 8 Aug.
