Abstract

B. bassiana is the most important and widely used entomopathogenic fungi for pest control but multiplication of adequate and good quality inoculum is important component in bio control approach. Solid media such as grains of rice, wheat, gram, pegion pea, vermicompost, Corcyra rearing waste and liquid media such as Potato Dextrose Broth (PDB) and Sabouraud’s Dextrose Broth (SDB) were evaluated for the mass production of B. bassiana. Results showed that Rice supported maximum conidial count at all 10, 20 and 30 days after incubation. Among liquid media, SDB supported maximum conidial count. Highest mean dry weight was recorded on gram followed by SDB. The highest growth rate of conidia was recorded on pigeonpea at from 10 to 20 days.

Conclusion

These findings concluded that all the solid and liquid media used as substrate supported the growth of B. bassiana. Spores are germinated irrespective of the substrate used as a medium for the growth of fungus. However, highest quantity of conidia was produced in the Rice among solid media and SDB yielded maximum conidia among liquid media. Hence rice is the best media for the mass multiplication of B.bassiana. Research has to be done to commercialization of bio-pesticides and made them easily available to the farmers at reasonable price.
