Field experiment was conducted to evaluate the efficacy of various insecticides against okra shoot and fruit borer, Earias vittella. Emamectin benzoate @ 0.36 gm/L was most effective followed by spinosad @ 0.5 ml/L and novaluron @ 1 ml/L in controlling fruit damage. Significant maximum yield of okra fruit was recorded from the plot sprayed with emamectin benzoate (89.16 q/ha) followed by spinosad (85.0 q/ha) and novaluron (77.50 q/ha). The maximum cost: benefit ratio was obtained from plots treated with fipronil with (1:11.76) followed by spinosad (1:8.77).
