Control of Lepidopterous Larvae with Insecticides, Pasquotank Co., NC, 1994

‘Blue Vantage’ cabbage was transplanted in late Jul near Weeksville, 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 backsprayer using a single hollow cone nozzle (18X) operating at 60 psi to deliver 54.5 gpa. Applications with Trigard AG-98 (spreader) were made with all treatments 22 Aug and 13, 20, and 27 Sep. No applications were applied between 22 Aug and 13 Sep. Counts were extremely low, and we allowed the DBM and CL populations to increase. A slight increase occurred and we applied treatments on 13 Sep. Visual estimates of foliar damage and insect counts were made 20 and 27 Sep and 3 Oct. No insects were present on 3 Oct.
