Seven rhizospheric myco-flora (Trichoderma harzianum, Trichoderma viride, Penicillium sp., three Aspergillus species and one was unknown) and four rhizobacteria (RB1- Pseudomonas fluorescence, RB2, RB3 and RB4) isolated from rhizosphere and were evaluated against sheath blight pathogen of rice Rhizoctonia solani Kuhn by dual culture technique. Among seven rhizospheric myco-flora T. harzianum has been shown highest growth inhibition 55.56% and has been followed by T. viride which produced 48.70%. Remaining myco-flora were showed comparatively less growth inhibition. Among rhizobacteria RB1 (Pseudomonas fluorescence) and RB2 have produced noticeable amount of growth inhibition compared with others 20.86% and 9.30% respectively.

Keywords: Rhizoctonia solani, Rhizospreric myco-flora, Rhizobacteria, Antagonism and dual culture technique
