Study on entomopathogenic of mass production of Beauveria bassiana on liquid and solid media

The present investigation entitled “Mass production of entomopathogenic fungi Beauveria bassiana (Metsch.) on liquid and solid media” was carried out at Bio Control Laboratory, Department of Entomology, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut during 2018-19. In all there were eight treatments including control replicated thrice in a randomized block design. The results obtained in the study are summarized. The substrate for cost effective of Beauveria bassiana spore/ ml (1x106) cost incurred for the production of spores T10 Savoured dextrose broth (SDB) was the best low cost substrate and high production showed in the table 1 (Rs 5.55 and 150. 25 spore/ml), T11 potato dextrose broth (PDB) (Rs 7.10 and 129.10 spore/ml), and solid substrate T8 cowpea (Vigna unguiculata) + Molasses + 1% YE + 1.0 g Dextrose (Rs 6.25 and 102.55 spore/ml) and T7 black gram (Vigna mungo) + Molasses + 1% YE + 1.0 g Dextrose (Rs 6.10 and 83.35 spore/ml).
