Six gram positive and three gram negative bacterial isolates effectively inhibited mycerial growth of R. solani by 30.62-75.00 % as compared to the control. Selected bacteria were further tested for the efficacy to promote growth of rice (Chai Nat 1) seedling by seed soaking in bacterial cell suspension (108 CFU/ml) for 24 hr.
