Type: article
Abstract: Studies were conducted at Agricultural Research Farm, Banaras Hindu University, Varanasi during Kharif 2010 and 2011 to know the efficacy of some new molecule insecticides (azadirachtin, Bt, endosulfan 35% EC, thiodicarb 75% WP, spinosad 45% SC, lambda cyhalothrin 5% EC, indoxacarb 14.5% SC, profenophos 50% EC and acetamiprid 20% SP) against spotted pod borer, Maruca vitrata (Geyer) on mungbean. The spinosad 45% SC and indoxacarb 14.5% SC were the most effective treatments and significantly superior to other treatments with 80.7 and 79.2 per cent larval reduction over control. The least effective treatment was acetamiprid 20%SP, followed by azadirachtin with 38.8 and 44.9 per cent reduction in larval population over control. The maximum yield was recorded in treatment indoxacarb 14.5%SC (11.8q/ha) followed by spinosad 45%SC (11.1q/ha) which were at par with each other. While lowest yield was recorded in azadirachtin (9.7q/ha).
