Effectiveness of different insecticides against whitefly (Bemisia tabaci) in sunflower

Abstract

The present field experiment were conducted to evaluate “Effectiveness of different insecticides against whitefly (Bemisia tabaci) in sunflower” under field condition during rabi season of 2017 at research farm of Oilseed Research Station, Latur, Maharashtra, India. The treatments of different insecticides viz., thiamethoxam 0.005 per cent, imidacloprid 0.00356 per cent, spiromesifen 0.02748 per cent, flonicamide 0.02 per cent, profenophos 0.1 per cent and triazophos 0.08 per cent were evaluated against whitefly, Bemisia tabaci revealed that imidacloprid 0.00356 per cent was found most effective treatment in reducing the population of whitefly (1.13 and 0.87 whiteflies per 6 leaves) followed by spiromesifen 0.12 per cent. Significantly higher seed yield (2450 kg/ha) of sunflower was recorded in treatment imidacloprid 0.00356 per cent however, it was found at par with treatment thiamethoxam 0.005 per cent (2264 kg/ha).
