The present study revealed the biological control of root rot in brinjal caused by Rhizoctonia solani Kuhn. Two Trichoderma spp. and two bacteria namely Bradyrhizobium japonicum and Bacillus thuringensis were screened against Rhizoctonia solani Kuhn. In vitro studies revealed that T. harzianum was found superior in restricting mycelial growth of R. solani followed by T. viride. In vivo assay the seed treatment with conidial suspension of bio-agent particularly T. harizanum (7.8x106 conidia ml-1) was found to be most effective in controlling root rot incidence followed by T. viride. In seedling treatment with conidial suspension only T. harizanum was found effective in reducing root rot incidence. Unautoclaved culture filtrate of T. harizanum was found effective even at lowest concentration of 10 % under In vitro studies. Only B. japonicum was found effective in arresting the mycelial growth under in vitro studies.
