Eggplant Insect Control, Johnston Co., N.C, 1995

‘Little Fingers’ eggplant were transplanted on 13 Jul at McGees Crossroads (MGX) near Benson, N.C. Single row plots 10 ft. long on 42 inch centers were replicated 4 times in a RCB 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. Visual estimates of foliar damage and insect counts were made 14 and 21 Aug. CPB pressure was low at the start of the season. After releasing adult CPB and moving larvae around in order to obtain a more uniform infestation the population then increased to heavy. Treatments were applied on 7 and 14 Aug. CPB counts were made on 14 and 21 Aug from 3 plants/plot. Small larvae were assumed to be first and second instar, and large larvae, third and fourth instar.
