Abstract: A field experiment was conducted at college of Agriculture, V.C. Farm, Mandya, University of Agricultural Sciences, Bangalore during summer 2015 to assess the efficacy of different new insecticides against leafhoppers. The results revealed that application of imidacloprid 17.8 SL @ 0.5 ml/l was found superior over the other treatments with higher per cent reduction (85.21 per cent) of pest population, followed by acetamiprid 20 SP @ 0.5 g/l, thiamethoxam 25 WG @ 0.3 g/l, acephate 95 SG @ 0.3 g/l, clothianidin 50 WDG @ 0.25 g/l which recorded 84.21, 83.41, 77.48, 74.62 per cent reduction of pest population, respectively. The next insecticides which proven better 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 60.25, 31.40, 22.14 and 17.23 per cent reduction, respectively.
