‘Old Fashion Cabbage’ collards were transplanted in late June near Benson, NC. Single row plots, 10 ft long on 42 inch centers were replicated 4 times in a randomized complete block design. Alleys of 5 ft were used between replicates. Treatments were applied with a CO2 pressurized backpack sprayer using a single hollow cone nozzle (18X) operating at 60 psi to deliver 54.5 gal/acre. Applications with Triton AG-98 (spreader) were made with all treatment 6, 12 and 20 Oct. Visual estimates of foliar damage and insect counts were made 12, 20, 27 Oct and 3 Nov.
