Abstract: Plant growth promoting bacteria not only promotes the growth of the plant but it protects the plant from disease causing pathogens by various modes. In this study, previously isolated metal tolerant, plant growth promoting bacterial isolates (R-57 and R-58) were taken for management of the fusarium wilt disease under in vitro and in vivo conditions. Under in vitro conditions, both the isolates R-57 and R-58 were found to effectively inhibit the radial mycelial growth of the pathogen by 44.4% and 55.5% respectively. In in vitro study, no wilting was observed in the plans treated with isolate R-57 and R-58 where as wilting incidence was observed in control plant, inoculated with F.oxysporum. On the base of present study, the biocontrol agents of plant diseases can be exploited for sustainable disease management and reduce environmental risk.
