Abstract

Study were conducted to find out the efficacy of commercially available insecticides formulations, Emmamectin benzoate 0.5% SG (0.5 g/lit. of water), Quinalphos 25% EC (2.0 ml/lit.), Novaluron 10% EC (1.0 ml/lit.), Neem oil 2% (20 ml/lit.), Karanj oil 2% (20 ml/lit.) against the Spilosoma obliqua in Clusterbean. The descending order of most effective insecticide was: Emmamectin benzoate > Quinalphos > Novaluron. During 2015, the maximum population reduction over control was found after 7 days of application of second spray at 15 days of interval viz., 75.4 and 72.0% due to Emmamectin benzoate and Quinalphos, respectively. A similar trend was found in 2016 and 2017. Thus, Emmamectin benzoate was found most effective against the Spilosoma obliqua.
