Ralstonia solanacearum, a soil borne pathogen is the major threat in cultivation of solanaceous crop which causing bacterial wilt diseases. Bio-fumigation is an alternative control method to suppress soil microorganisms, such as fungal, bacterial pathogens and nematodes. Soil incorporation of Brassica spp. viz., B. olaraceae (cabbage), B. carinata, B. nigra, B. juncea, B. napus, mustard seed cake and B. caulorapa were found effective in reducing the bacterial wilt disease with 86.94 per cent disease control  over untreated under glasshouse condition.  Field experiments with incorporation of brassica spp. also reduced the incidence of bacterial disease in infested soil. B. olaraceae (cabbage) was found more effective in suppression of bacterial wilt with 69.33 per cent disease over control among the different Brassica spp. treatments undr field condition   followed by B. juncea and B. carinata with 66.78 per cent disease control over untreated control at 45 days after planting. Mustard seed cake with 62.81 per cent disease control, Raphanus sativus (radish), B. caulorapa (Knol khol) and B. napus with 57.04 per cent disease control were found next best bio fumigant. In streptomycine (standard check) treated plot.52.28 per cent disease control was observed.

Key words: Bio-fumigation, Brassica spp., Bacterial wilt.
