A metabolic diversity in rhizospheric microorganisms plays a major role in plant pathogen suppression and plant growth promotion. To be active, the microorganism secrets the diverse metabolites in minor quantity in pico or nano gram. In this study antifungal metabolites and silver nanoparticles producing Pseudomonas species were isolated from rhizosphere of Bt cotton plant. A combinatory effect of silver nanoparticles, Pseudomonas species/metabolites was evaluated against two cotton plant pathogens Fusarium oxysporium and Aspergillus niger. The experimental results were analysed using MINITAB (ver. 17) for ANOVA (p < 0.05) indicate that the addition of silver nanoparticles increases fungal growth inhibition and plant growth promotion efficiency.
