Management of root rot and collar rot of soybean by antagonistic microorganism

Root/collar rot is a destructive disease of Soybean in India. Seed treatment with bioagents were found effective in reducing the root/collar rot disease incidence. Percent disease incidence was worked out with Rhizoctonia, Sclerotium and Rhizoctonia + Sclerotium sick soil at 20 DAS and at flowering by conducting pot culture experiment. Among different treatments the most effective was seed treatment with Pseudomonas fluorescens @ 10g/kg of seed + Bradyrhizobium japonicum @ 20g/kg of seed + Pseudomonas striata @ 20 g/kg of seed with minimum disease incidence i.e. 8.86%, 13.33%, 20.00% at 20 DAS and 17.73%, 33.33% and 40.00% at flowering, respectively.
