Author(s): Shashitu Aleling*
Ralstonia solanacearum causes bacterial wilt of tomato and limits the crop production, and antagonistic microorganisms such as fungi and bacteria are used to suppress the disease, of which Trichoderma spp. and Pseudomonas spp. are the most effective agents to control bacterial wilt of various horticultural and other crops. In the present study, attempt was made to isolate these two microorganisms to evaluate their effectiveness to control R. solanacearum the causal agent of bacterial wilt disease of tomato under greenhouse conditions. Thus R. solanacearum, Pseudomonas and Trichoderma spp. were isolated from wilted and healthy tomato plants grown from farmer's field in Ziway and Meki. The virulence of the pathogen and the antagonistic effect of the bacteria and fungi were evaluated against R. sola.. View more»
