Bacterial wilt caused by Ralstonia solanacearum is one of the most destructive bacterial diseases of tomato and other economically important crops.
To develop a biological control strategy against the pathogen,150 isolates of rhizobacteria were isolated and screened for in vitro antibiosis.
Bacterial wilt caused by Ralstonia solanacearum is one of the most devastating bacterial diseases in the tropics,subtropics and warm temperature regions of the world.The pathogen is a Gram-negative soil-borne b-Proteobacterium with an extensive host range of over 450 plants species in 54 families.Tomato (Solanum lycopersicum) is one of the economically important host plants which are attacked by the pathogen apart from others such as potato, banana, egg plant and ginger.
