Field experiments were conducted in two crop seasons during 2014 and 2015 at Bidhan Chandra Krishi Viswavidyalaya, Kalyani, West Bengal to evaluate the efficacy of some novel mode of insecticides like Buprofezin 25% SC, Flonicamid 50% WG, Spiromesifen 22.9% SC, Spirotetramat 240 SC, Sulfoxaflor 24% SC, Clothianidin 50% WDG, Dinotefuran 20% SG along with some standard chemicals, Imidacloprid 17.8% SL @ 0.5 ml/l and Thiamethoxam 25% WG @ 0.3 gm/l against Jassid [Amrasca biguttula biguttula (Ishida)] infesting cotton variety Surabhi. Nine numbers of insecticides with untreated control, altogether ten treatments replicated three times were done in the experiment. Results revealed that all the treated plots gave significant reduction of jassid population while there was a sharp increase in pest population in the untreated control. Among the treatments, the most effective insecticide was Buprofezin 25% SC @ 1.6 ml/l (80.16%) followed by Imidacloprid 17.8% SL @ 0.5 ml/l (78.77%) and least effective was Sulfoxaflor 24% SC @ 0.3ml/l (69.45%).
