Pronobesh Halder, Sourav Basak, Madhab Kumar Datta and Monilal Chatterjee

Nine insecticides, viz. Buprofezin 25% SC, Flonicamid 50% WG, Spiromesifen 22.9% SC, Spirotetramat 240 SC, Sulfoxaflor 24% SC, Clothianidin 50% WDG, Dinotefuron 20% SG, Imidacloprid 17.8% SL and Thiamethoxam 25% WG were evaluated for their efficacy against white fly (Bemisia tabaci (Genn.)) of cotton (cultivar Surobhi) at ā€œCā€ block farm of Bidhan Chandra Krishi Viswavidyalaya, Kalyani, West Bengal during rabi season of 2014 and 2015. The experiment was designed with ten treatments (including control) and tested under Randomized Block Design with three replications. Results revealed that all the treated plots gave significant reduction of white fly population while there was a sharp increase in pest population in the untreated control in both the year. Among the treatments, the most effective insecticide was Spiromesifen 22.9% SC @ 1gm/l (85.97%) followed by Buprofezin 25% SC @ 1.6 ml/l (83.47%) and least effective was Sulfoxaflor 24% SC @ 0.3ml/l (67.63%).
