Author(s): T Hemadri, L Vijaykumar, G Somu and MR Moulya

Abstract: A field experiment was conducted to know the efficacy of new insecticides against whitefly, Bemisia tabaci Genn,) on okra under high pest pressure during summer 2015 at college of Agriculture, V.C. Farm, Mandya University of Agricultural Sciences, Bangalore. The results revealed that, foliar spray of Imidacloprid 17.8 SL @ 0.5 ml/l was found to be most effective against whiteflies with higher per cent reduction of pest population (84.54 per cent), followed by acetamiprid 20 SP @ 0.5 g/l, thiamethoxam 25 WG @ 0.3 g/l, acephate 95 SG @ 0.3 g/l, and clothianidin 50 WDG @ 0.25 g/l which recorded 84.36, 84.25, 76.38 and 73.53 per cent reduction in the pest population, respectively. The next best treatments were cyantraniliprole 10.26 OD @ 1 ml/l, oxydemeton methyl 25 EC @ 1.5 ml/l, imidacloprid 17.8 SL seed coating @ 4:20 ml/kg and thiamethoxam 25 WG seed coating @ 2:20 ml/kg which registered 59.98, 31.47, 25.16 and 19.25 per cent reduction, respectively.
