Efficacy of entomopathogenic fungi for the management of soybean defoliators, green semilooper and tobacco leaf eating caterpillar in field condition at Entomology section, College of Agriculture, Nagpur during kharif season of 2017-18, in randomized block design with three replications with the Metarhizium anisopliae, Beauveria bassiana and Nomuraea rileyi at 1×10⁸ and 1×10⁹ cfu/ml formulations were evaluated in comparisons with Spinosad 45 SC @ 0.25 ml/L. Based on data of two sprays, it was observed that Spinosad 45 SC @ 0.25ml/L had offered maximum larval reduction (67.29 %) and found significantly superior over all the other treatments. Among the entomopathogenic fungi M. anisopliae 1×10⁹ cfu/ml had maximum larval reduction and was found most effective. The maximum yield was recorded in plot treated with Spinosad 45 SC @ 0.25ml/L (18.48 q/ha) and recorded lowest ICBR (1:4.36) as it was expensive. Maximum net profit was recorded in the treatment of M. anisopliae 1x10⁹ cfu/ml with highest ICBR (1:10.70).
