Abstract:

An inspection was undertaken to study the bio-efficacy of different insecticides against defoliator (Spodoptera litura) on sunflower under field condition during Kharif, 2019 at research farm of Oilseed Research Station, Latur, Maharashtra, India. The observations on total number of Spodoptera litura were recorded on five randomly selected plants from each treatment at one day before and 3, 7 and 14 days after first and second application of insecticides. The treatments of different insecticides viz., indoxacarb 0.019 per cent, emamectin benzoate 0.006 per cent, quinalphos 0.03 per cent, chlorantraniliprole 0.024 per cent, cypermethrin 0.03 per cent and profenophos 0.06 per cent were evaluated against Spodoptera litura revealed that emamectin benzoate 0.006 per cent was found most effective treatment in reducing the population of S. litura (0.07 and 0.00 larvae per five plants per plot at 3 days after first and second spray respectively), followed by chlorantraniliprole 0.024 per cent. Significantly higher seed yield (2846 kg/ha) of sunflower was recorded in treatment emamectin benzoate 0.006 per cent, it was followed by treatment chlorantraniliprole 18.5 per cent (2656 kg/ha). The highest ICBR (1:15.31) was recorded with treatment emamectin benzoate 0.006 per cent which was followed by cypermethrin 0.03 per cent (1:11.55).
