A simple and cost effective technique for in vitro conidial mass production of B. bassiana and M. anisopliae has been developed by using different vegetable based liquid media. In case of B. bassiana, PDB was found to be the best media with biomass production of 1.20 g/100 ml, conidial count 14.1×107 and conidial viability 93 per cent. The least biomass production was recorded from Ipomoea batata with biomass production of 0.88 g., conidial count 4.30×107 and conidial viability 71 per cent, while in case of M. anisopliae, Ipomoea batata yielded highest biomass (1.31) with condial count of 11.43×107 and conidial viability of 92 per cent. Least biomass was recorded from Dioscorea sp. with biomass production of 0.08 g, conidial count 0.56×107 and conidial viability 80.33.
