Abstract :

Plant growth promoting bacteria play an important role in agriculture by promoting beneficial effect, it gives novel and potential tool to replace chemical fertilizer, pesticides and supplements. The aim of the present study was to evaluate biocontrol efficacy of plant growth promoting bacteria isolated from agricultural soil of Pune and Aurangabad district. In present study ten plant growth promoting bacteria were isolated and selected and screened in vitro for detecting plant growth promoting traits like production of indole acetic acid (IAA), Ammonia, HCN, Siderophore, Phosphate solubilization and also evaluated for biocontrol efficacy of siderophores produced by isolated bacteria against some fungal phytopathogens such as A .nigar, Fusarium oxysporum, Curvularia sp. Helminthosporium sp. Colletotrichum and A.flavous. Antifugal activity of Siderophore was determined by agar well diffusion method. It was observed that four isolates namely V1, P1, P3 and L2 showed the significant production of Siderophores and showed potential biocontrol agent against fungal phytopathogens. Siderophores are useful in plant growth improvement and disease management. Agricultural microbiologists have interests in using beneficial microbes as a solution for the over use of potentially harmful chemical fertilizer and pesticides
