Bacillus subtilis is one of the potential PGPR and biocontrol agent against several plant pathogens of important crop plants.  In the present study thirty isolates of B. subtilis were isolated from different rhizosphere soil samples from different parts of North Eastern Karnataka region. All the rhizospheric isolates were rod shaped, positive for gram reaction, endospore, oxidase, catalase, starch hydrolysis, negative for indole, KOH test and green coloured colonies were grown on Hichrome Bacillus agar medium. All the thirty isolates of B. subtilis were tested for their efficacy against C. capsici under in vitro. All the isolates showed the varied level of inhibition of mycelial growth of C. capsici. Among different isolates, BS16 showed maximum 63.42 per cent followed by BS 30 (57.40 %) inhibition and minimum was 11.98 per cent in case of BS 24 compared to check (56 %). Biological control is by using antimicrobial agents an attractive option which reduces the use of chemicals in the management of diseases of chilli.
