Abstract

Study was conducted to evaluate the effect of insecticides namely, Imidacloprid 17.8% SL (0.33 ml/lit.), Acetamaprid 20% SP (0.4 g/lit. of water), Thiamethoxam 25% WG (0.5 g/lit.), Quinalphos % 25 EC (2.0 ml/lit.), Neem oil 2% (20 ml/lit.) and Karanj oil 2% (20 ml/lit.) against the Thrips, Megalurothrips usitatus in Green gram. The most effective insecticide was Imidacloprid > Thiamethoxam > Acetamaprid. The maximum population reduction over control was found after 7 days of 2nd spray at 15 days of interval viz., 80.7, 75.8 and 81.5% due to Imidacloprid during 2015, 2016 and 2017 years of treatment.
