The field investigation was carried out in Kharif season of 2022 at Central Research Farm (CRF), Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. The experiment was laid in Randomized Block Design with eight treatments each replicated thrice viz., Emamectin benzoate 5% SG (5 g/lit), Lambda cyhalothrin 2.5% EC (0.5-1 ml/lit), Flubendiamide 480 SC (0.3 ml/lit), Imidacloprid 17.8% SL (1 ml/2.5 lit), Chlorantraniliprole 18.5% SC (0.5 ml/lit), Neem oil @2% (20 ml/lit), Spinosad 45% SC (0.3-0.4 ml/lit), and control plot. The result revealed that among all the treatments lowest percent shoot infestation and fruit infestation  of okra shoot and fruit borer was recorded in Chlorantraniliprole 18.5% SC (13.90%), (13.11%) at both sprayers followed by Spinosad 45% SC (15.89%), (14.25%), Emamectin benzoate 5% SG (16.59%), (15.02%), Flubendiamide 480 SC (17.27%), (15.30%), Imidacloprid 17.8% SL (17.44%), (16.63%), Lambda cyhalothrin 2.5% EC (19.09%), (16.97%),  Neem oil @2% (19.21%), (17.23%) and Control (30.87%), (25.44%). The highest yield and cost benefit ratio was recorded in Chlorantraniliprole 18.5% SC (158.33 q/ha), (1:6.1) followed by Spinosad 45% SC (153.33 q/ha), (1:5.4), Emamectin benzoate 5% SG (133.33 q/ha), (1:5.3), Flubendiamide 480 SC (116.66 q/ha), (1:4.7), Imidacloprid 17.8% SL (105 q/ha), (1:4.2), Lambda cyhalothrin 2.5% EC (83.33 q/ha), (1:3.3), Neem oil @2% (70 q/ha), (1:2.8) and Control plot (33.33 q/ha), (1:1.3).
