A field trial was conducted to assess the efficacy of bio-rational insecticides against major insect pests of greengram. Spinosad 45 SC @ 200 ml/ha was the most effective across all pests. It achieved mean population reductions of 72.60% and 75.41% for aphids, 71.65% and 75.19% for whiteflies, 72.30% and 73.66% for jassids, and 70.33% and 72.54% for pod borers at 7 days after the first and second sprays, respectively. Abamectin 1.9 EC @ 500 ml/ha was the second most effective against sucking pests, while Emamectin benzoate 5 SG @ 200 g/ha showed notable efficacy against pod borers. The highest seed yield of 10.07 q/ha was recorded in Spinosad-treated plots, recording 29.93% increase over the control (7.75 q/ha). Emamectin benzoate-treated plots yielded 9.50 q/ha with a 22.58% increase, while NSKE 5% resulted in the lowest yield improvement (8.64%).
