In vitro Evaluation of Actinobacteria against Tomato Bacterial Wilt (Ralstonia solanacearum EF Smith) in West Showa, Ethiopia

The management of tomato against this pathogen is important to maximize the crop's yield.Chemicals either not have direct bactericidal or fungicidal activities against the pathogen or converted into non-toxic derivatives by the pathogen.Management of this disease through chemicals and the use of resistant varieties are possible, but the hazardous impact of agrochemicals on the human health and environments, development of resistant mutants, escalating costs of fumigant pesticides and frequent breakdown of resistant varieties; strongly demand a sustainable and alternative disease management approaches [6].Many bio-control agents (BCA) have been successfully identified for the control of various plant pathogens as alternative disease
