The field experiment was conducted to evaluate the effectiveness of seven ready-mix insecticides against fruit borers i.e. Earias vittella (Fab.) and Helicoverpa armigera (Hübner) Hardwick in okra at Main Vegetable Research Station, Anand Agricultural University, Anand (Gujarat) during summer and kharif, 2016. Among seven different ready-mix insecticides evaluated for their relative bio-efficacy, chlorantraniliprole 9.3% + lambda cyhalothrin 4.6% ZC (0.007%) and indoxacarb 14.5% + acetamprid 7.7% SC (0.022%) found most effective against fruit borers by recording less larval population and fruit damage on both number as well as weight basis which followed by profenophos 40% + cypermethrin 4% EC (0.044%). The maximum fruit yield of okra fruit was harvested from the plots treated with chlorantraniliprole 9.3% + lambda-cyhalothrin 4.6% (68.44 and 151.12 q/ha) followed by indoxacarb 14.5% + acetamprid 7.7% SC (62.72 and 145.83 q/ha)during summer and kharif, respectively. Maximum net realization was obtained in the treatment of chlorantraniliprole 9.3% + lambda-cyhalothrin 4.6% ZC (`87895/ ha and `85103/ ha) followed by indoxacarb 14.5% + acetamprid 7.7% SC (`76868/ha and `80226/ha) during summer and kharif, respectively.
