A field experiment was conducted to evaluate the efficacy of different insecticides against Cydia ptychora (Meyrick) and Etiella zinckenella (Treitschke) in Kharif 2021. Among all tested chemicals and biorationals, chlorantraniliprole proved very effective in controlling the C. ptychora larvae (80.95%) followed by indoxacarb 15.8 EC which controls 76.85 percent. While azadirachtin (41.93%) and NSKE (32.43%) were lest in controlling the C. ptychora larvae, respectively. In case of E. zinckenella highest percent reduction, 89.54 was recorded in chlorantraniliprole treated plots, followed by indoxacarb (81.34%). NSKE was found to be the least effective by recording 68.87 percent when compared to untreated control. The higher cost-benefit ratio of 1:3.47 was recorded in chlorantraniliprole treated plot followed by indoxacarb (1:3.20).
