Stem rot is one of the most drastic diseases of groundnut that cause major crop loss. Stem rot pathogen of groundnut, Sclerotium rolfsii, was isolated from the infected groundnut stem. Present investigation was started to search for effective biocontrol agent against Sclerotium rolfsii. To find effective biocontrol agent, 120Bacillus spp. isolated from various rhizospheric soils of healthy plants, screened in vitro against the stem rot pathogen by dual culture technique. Out of these Bacillus spp, Bacillus 57isolate found effective in controlling the phytopathogen by Novel Ring method (80.21 %). Bacillus 57was identified by 16S rRNA sequencing as Bacillus thuringiensis NCIM2130. To effectively control the phytopathogen in vitro, the Bacillus thuringiensis NCIM2130 produced the Volatile metabolites, and Siderophore.

Keywords: Stem rot,Sclerotium rolfsii, Bacillus thuringiensis NCIM2130,Siderophore.
