The field experiment was conducted on paddy at farmer's field in the Kangra district, to find out the effectiveness and economically viable control measures for the management of white stem borer. Application of various insecticides viz. flubendiamide 48% SC @ 50 ml ha−1, rynaxypyr 20 SC @ 150 ml ha−1, dinotefuran 20 SG @ 200 g ha−1, monocrotophos 36 SL@850mlha−1 and twobiopesticides viz. melia 5% @ 2.5 L ha−1and eupatorium 5% @ 2.5 L ha−1, were tested along with untreated control. All the insecticidal treatments were found significantly superior to untreated control. Flubendiamide 48% SC @ 50 ml ha−1 and rynaxypyr 20 SC @ 150 ml ha−1 were found most promising with minimum dead heart and white ears. The data on dead heart, white ear incidence and grain yield showed that all the insecticides were found to have effective control against stem borer on paddy. Considering the efficacy data with very low dose of flubendiamide 48% SC proved to be better and economically viable option for management of stem borer.
