Abstract: The field investigation was carried out at Central Research Farm (CRF), Department of Entomology, Sam Higginbottom University of Agriculture, Technology and Sciences. Prayagraj, Uttar Pradesh during Rabi season 2023-24. The experiment was laid in Randomized Block Design with eight treatments replicated thrice viz, treatment with doses. The result after two sprays reveled that the lowest percent shoot and fruits, infestation after first and second spray was recorded in treatment Chlorantraniliprole 18.5% SC (9.94%), Spinosade 45% SC (10.51%), Indoxacarb 14.5% SC (10.82%), Emamectin Benzoate 5% SG (11.43%), Flubendamaide 480% SC (11.88%), Beauveria bassiana 1.15% WP (12.57%), Neem oil 2% (13.12%), Control Plot (15.95%). The crop yield ranged between 221 q/ha to 90.50 q/ha in the treatments and BCR ranged between 1:9.9 to 1:4.6. The plot treated with chlorantraniprole 18.5 SC showed highest yield and BCR of 221 q/ha and 1:9.9 and found to be most effective treatment next to which Spinosad 45 SC (195.13 q/ha, 1:9.3) Indoxacarb 14.5SC (185.87 q/ha, 1:9.0), Emamectin Benzoate (178.95 q/ha,1:8.5), Flubendiamide 480 SC (170.43 q/ha,1:8.0), Beauveria bassiana 1.15% WP (165 q/ha,1:7.9). Neem oil @ 2% (150.69 q/ha 1:7.2) as compared to untreated control plot (90.50 q/ha, 1:4.6).
