With the basic principle of integrated pest management (IPM) and searching for effective and sustainable alternatives for the management of Spodoptera frugiperda, different biopesticides were evaluated at Main Agricultural Research Station (MARS), UAS Raichur, Karnataka during Kharif 2019 cropping season. The experiment was laid in a Randomized Complete Block Design (RCBD) with three replications and seven treatments. Biopesticides such as Metarhizium rileyi, SfNPV and Bacillus thuringiensis var. kurstaki were found to be the best treatments in reducing the larval population and per cent leaf damage compared to untreated control at five and seven days after two sprays. The yield and cost economics also showed that they were economically viable biopesticides.
