Rice sheath blight(Rhizoctonia solani) is one of the most important and widespread fungal disease worldwide. Although different management options like fungal and bacterial antagonists, fungicides and soil amendments are reported to be the effective against sheath blight and also increase plant growth as well as grain yield. The present study aimed towards developing a sustainable management of sheath blight disease through sole as well as combined application of these options. Three field trials were conducted during kharif season to assess the per cent disease index (PDI) and grain yield. Out of ten treatments including control the lowest PDI was observed in carbendazim+sawdust treatment (32.89).The highest PDI was found in carbendazim+sawdust treatment (22.30). All treatments showed significant decrease in PDI over control. The grain yield was observed 50.37q/ha in Trichoderma viride + Pseudomonas fluorescens followed by carbendazim + FYM (49.22q/ha). The per cent increase in yield was found highest in Trichoderma viride + Pseudomonas fluorescens treatment (55.22).  All treatments found significant in grain yield over control.

Key words: Rice sheath blight, Rhizoctonia solani, Sustainable management, PDI, Grain yield.
