Rice is an important staple food for more than half of the world’s population and is subject to diseases that often place major biological constraints on production. Sheath blight of rice is caused by a soil borne fungus and biological control of the disease is an efficient substitute to replace chemical methods. In the present study thirty native fluorescent Pseudomonads, an efficient biocontrol agent have been isolated and confirmed by cultural, morphological, biochemical characterization and visualization under UV light. The isolates were screened in vitro for antagonistic activity against Rhizoctonia solani, three strains among them i.e., DMP1 (53.43%), DBP (51.53%) and PVP2 (48.26%) were found to inhibit mycelial growth significantly. The antagonistic activity of the three isolates was further tested by applying them as seed treatment, root dipping and foliar spray in the rice crop under greenhouse conditions. Among all the treatments when compared by inoculating with Rhizoctonia solani at the maximum tillering stage, the T5 treatment (Seed treatment with DMP1 + Inoculation of Rhizoctonia solani) not only enhanced the plant growth but also showed the reduction in disease severity of 41.12% when compared with the control.
