Abstract: The field trial was conducted at the Central field, Department of entomology SHUATS, Allahabad during Kharif from August to November 2016 investigation entitled “Field efficacy of Cypermethrin and certain biopesticides against shoot and fruit borer (Leucinodes orbonalis Guenee) on brinjal (Solanum melongena L.). Seven treatments were evaluated against Leucinodes orbonalis i.e., T1 Cypermethrin 25 EC@ 2ml/lit, T2 Spinosad 45 SC @ 0.01%, T3 Neem Oil 2%, T4 NSKE 5%, T5 Beauveria bassiana, T6 Verticilium lecanii, T7 Neem leaf extract 5% were evaluated against shoot and fruit borer Leucinodes orbonalis. Cypermethrin 25 EC, Spinosad 45 SC, and Neem oil recorded the minimum shoot infestation by 5.90, 7.33, and 9.83 percent respectively. In fruit infestation Cypermethrin 25 EC, Spinosad 45 SC, and neem oil recorded by 3.69, 4.06, and 5.17 percent, respectively. The best and most economical treatment was T1 Cypermethrin 25 EC (1:8.05), followed by T2 (1:7.60), T3 (1:6.04), T4 (1:4.79), T5 (1:5.03), T6 (1:4.95), T7 (1:4.00), as compared to control T0 (1:3.73). The highest yield was noticed in Cypermethrin 25 EC (204.16 q/ha) followed by Spinosad 45 SC (197.22 q/ha).
