Online published on 23 October, 2018. Abstract The field trials were carried out at PAU Krishi Vigyan Kendra, Gurdaspur during kharif 2015 and 2016 to evaluate the efficacy of chlorantraniliprole 20 SC, flubendiamide 480 SC, spinosad 45 SC and fipronil 80 WG @ 150, 50, 150 ml and 37.5 g/ha, respectively against stem borers and leaf folder in basmati rice. All the insecticides significantly reduced the incidence of stem borers and leaf folder and minimized the yield loss. Pooled analysis indicated significant reduction in folded leaves (0.53%), deadhearts (0.91%) and white ears (1.10%) with flubendiamide @ 50 ml/ha as compared with other insecticidal treatments. Flubendiamide was also safer to predaceous spiders and minimized the yield loss in basmati rice by 25%.
