Biological control of Rhizotonia bataticola on gram by coating seed with antagonistic microorganisms was investigated. Initially microorganisms were selected from bacteria and actinomycetes isolated from a loam soil and creeened for antagonism to R. bataticola on potato dextrose agar. Four bacterial isolates and six actinomycete isolates proved antagonistic to R. bataticola in petridish tests and were tested further by coating gram seed in field soil inoculated with R. bataticola. These antagonists significantly reduced symptoms caused by R. bataticola and also increased plant growth and dry matter production of gram. However, a strain of Streptomyces was ineffective and did not control disease
