The objective of this experiment was to assess the efficacy of variousOMRI and reduced-risk insecticides for control of EFB on eggplantin a central West Virginia field environment. Nine-wk-old ‘Calliope’eggplant was transplanted on 4 Jun at a privately owned farm inClay County, WV. The experiment consisted of six treatments arrangedin an RCB design with four replicates. Plots consisted ofsingle rows containing 10 plants spaced 46 cm apart with 0.9 mbetween rows and 0.9 m between treatments. Treatments includedBoteGHA ES (11.3% solution of Beauveria bassiana Strain GHA;2 × 1013 viable spores/quart) at 1 qt/acre, Entrust SC (spinosad) at3 oz/acre, Neemix 4.5 (Azadirachtin) at 16 oz/acre, Pyganic EC 5.0(pyrethrins) at 17 oz/acre, Verimark SC (Cyantraniliprole) at 13.5 floz/acre, and an untreated check. Verimark was applied as a transplanttray drench 3 d before transplanting eggplant into the field. Allother insecticide treatments were applied as foliar sprays at approximatelyweekly intervals on 15, 22, and 29 Jun, and 6, 11, and 22Jul using a CO2 pressurized backpack sprayer calibrated to deliver57 GPA at 30 psi through a single TeeJet 8002VS flat fan nozzle.Sampling was conducted prior to application of foliar-appliedinsecticides. The number of EFB on six plants from the center ofeach plot was recorded. Leaf feeding injury was also assessed fromall plants in each plot using the following percent defoliation scale:1 = no defoliation; 2 = 1–20% defoliation; 3 = 21–40% defoliation;4 = 41–60% defoliation; and 5 = 61% defoliation. All data wereanalyzed using ANOVA, and means were separated using Fisher’sLSD test (P ≤ 0.05).
