Abstract
Bacillus thuringiensis (Bt) suppressed the growth Of Pythium ultimum a nd Fusarium oxysporum f. sp. lycopersci and lysed the mycelium. Scanni ng electron micrographs showed the attachment of Bt cells to the hypha e of host pathogens. Bt cells attached to hyphae of P. ultimum polarly and externally, causing its deformation and lysis. In case of F. oxys porum f. sp. lycopersici, the attachment was random and at a few place s Bt cells entered the hyphae and caused lysis.
