Abstract

Plant growth-promoting rhizobacterial strains belonging to fluorescent pseudomonads were isolated from the rhizosphere of rice. Among 30 strains that were confirmed as Pseudomonas fluorescens, these P. fluorescens strains was characterized by PCR-RAPD analysis and biochemical methods. Ten exhibited strong antifungal activity against P. oryzae and R. solani mainly through the production of antifungal metabolites.
