Efficacy of various insecticides against okra shoot and fruit borer, Earias vitella (Fab.)

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).
