The objective of this study was to isolate and test the efficacy of pseudomonas aeruginosa which produces antifungal substances, to inhibit plant pathogenic fungi. The soil bacterium pseudomonas aeruginosa was isolated from the Rhizosphere soil, showed high antagonistic activity against Rhizoctonia solani, isolated from Rhizosphere region of rice (Oryzasativa) plant using dual culture and volatile assay. The isolated bacteria were subjected to antagonistic activity against Rhizoctonia solani. The four (4) isolates were selected out of eleven. Pseudomonas aeruginosa was found to be highly effective in suppressing the growth of fungal plant pathogens (Rhizoctonia solani), hence it can be used as biocontrol agent.
