Abstract: Mulberry is only source of food for the silkworm Bombyx mori L. Mulberry is susceptible to soil borne diseases among them root rot is fast spreading disease caused by F. solani. The pathogen can be managed by synthetic chemical fungicides but use of synthetic fungicides lead to residual toxicity effect the growth and development of silkworm. In this context, an attempt was made to use of antagonistic bio control agents for the management of this root rot pathogen. Seven fungal bio control agents and five bacterial bio control agents tested out of them T. viridae (Tv – B2), T. harzianum (Th - 44), B. subtilis (Bs-M) and (Bs-O) were proved as best for inhibition of mycelial growth of the pathogen. Out of eleven plant extracts used, garlic was proved best at 15 per cent and 20 per cent concentrations and agave at 20 per cent found effective against the root rot causing pathogen.
