Abstract: The laboratory experiment was carried out at Plant Pathology Department, College of Agriculture, Nagpur during 2018-19 to assess the pathogenicity of Metarhizium anisopliae against Spodoptera litura and its compatibility with insectides. The isolates of Metarhizium anisopliae were collected from the field and tested against Spodoptera litura larvae for its pathogenicity in laboratory condition by leaf dip method. The laboratory study revealed that, the spore suspension of 1x109 spore ml-1 recorded highest mortality of 91.66 per cent whereas, the spore suspension of 1x105 spore ml-1 recorded minimum mortality of 33.33 per cent. The mortality rate was decreased with decrease in the spore suspension concentration and maximum per cent mortality was recorded as the increase in concentration of the inoculum. Compatibility of Metarhizium anisopliae was tested with insecticides viz., imadicloprid, spinosad, chloropyriphos and indoxacarb by poisoned food technique and it was observed that, Metarhizium anisopliae slightly tolerate to the toxic effect of spinosad and imidacloprid at the recommended dose of insecticides whereas, chloropyriphos and indoxacarb produced more toxic effect at normal concentration of insecticidal dose
