abstract
A field experiment was conducted to determine the comparative efficacy of combination insecticides with some conventional insecticides against lepidopteran pests of rice. All the tested chemicals are effective for different pests in rice, but among the tested insecticide molecules profenofos 40%+cypermethrin 4% (44%) EC @ 1000 ml per ha, profenofos 40%+cypermethrin 4% (44%) EC @ 750 ml per ha, profenofos 40%+cypermethrin 4% (44%) EC @ 500 ml per ha can be used for the effective management of lepidoperan pests on paddy. With reference to yield the plot treated with these insecticides were shown higher yield compared to untreated check. The higher yield 50.98 q/ha was noticed in the plot treated with profenofos 40%+cypermethrin 4% (44%) EC @ 1000 ml per ha and lowest yield 32.95 q/ha was noticed in untreated plot.
