Comparative efficacy of selected insecticides, botanicals and biopesticides on infestation of jassid (Amrasca biguttula biguttula Ishida) on okra (Abelmoschus esculentus L. Moench)

The results showed that flonicamid 50% WG, (1.35/3 leaves), Imidacloprid 17.8% SL (1.65/3 leaves), thimethoxam 25% WG (2.83/3 leaves), azadirachtin 5% (3.46/3 leaves) were comparable but neem oil (4.28/3 leaves), Verticillium lecanii (6.75/3 leaves), and spinosad 45% SC (6.75%/3 leaves) were found least effective treatments but superior to the control. The best and most economical treatment was flonicamid 50% WG (1:4.05), followed by imidacloprid 17.8 SL (1:3.87), thimethoxam 25% WG (1:3.62), azadirachtin 5% (1:3.44), neem oil (2.90), Verticillium lecanii (1:2.00) and spinosad 45% SC (1:1.65) as compared to control (1:1.23). The highest yield was recorded in flonicamid 50% WG 50 (1:4.05 q/ha) followed by Imidacloprid 17.8% SL 1:3.87 q/ha).
