A field experiment on bioefficacy of newer insecticides against the important insect pests was conducted using three sys-temic and three contact insecticides along with untreated check (UTC). The results revealed that the treatment with thiamethoxam 25 WG @ 0.2 g/l recorded 10.48 aphids/5 cm top shoot length (83.85% reduction over UTC). Management with respect to capsule borer and the safflower caterpillar chlorantraniliprole 20 SC @ 0.15 ml/l was superior with mean larval population of 0.84 larvae/plant and 0.77 larvae/plant (82.90 and 82.53% reduction over UTC, respectively). Highest benefit cost ratio was obtained in chlorantraniliprole 20 SC @ 0.15 ml/lit (2.85) followed by thiamethoxam 25 WG @ 0.2 g/l (2.81), buprofezin 50 SC @ 0.2 ml/l (2.51) and emamectin benzoate 5 SG @ 0.2 g/l (2.47).
