During Rabi 2021, field experiments were undertaken in blackgram to evaluate commercial liquid and wettable powder formulations of Metarhizium anisopliae against Spodoptera litura in Blackgram. Field trial were carried out in Randomized Block design (RBD) with six treatments and four replications at Department of Entomology, Annamalai University. Pre-treatment count were taken at 1 m2 area. Both liquid and wettable powder formulations of M. anisopliae were mixed in water and sprayed during early morning and evening hours. Two sprays of each formulation of M. anisopliae, were given against S. litura at an interval of 15 days. Mean larval population of S. litura were assessed at 5, 10 and 15 DAT respectively. Collected data were subjected to square root transformation. Liquid formulations of M. anisopliae were found to be effective against S. litura.
