Review on ginger bacterial wilt (Ralstonia solanacearum Smith) and its management approaches: The case of Ethiopia
Ginger Bacterial wilt disease posed a threat to ginger production in countries where ginger is produced. It is caused by Ralstonia solanacearum (Smith) biovar III race 4. Having knowledge on biology, distribution and possibl ways to manage the disease is important in designing cost Effective management strategies of the disease. The objective of this paper was to give an Overview on biology, distribution, importance and management approaches of ginger bacterial Wilt caused by Ralstonia solanacearum (Smith). Ralstonia solanacearum is distributed in many Habitats all over the world and has broad host range. It is seed and soil borne pathogen that can easily transfer from one cropping season to the next by infected seed piece and soil. The symptom of the disease can be seen on above ground and underground parts of ginger plant. Efforts have been made to manage the disease in many countries including Ethiopia. Available management options for the disease are using biological control agents, cultural methods, chemical methods and integrated disease management. Integration of different management options like the use of chemicals, biological control agents, and organic amendments were found better controlled infection caused by Ralstonia solanacearum (Smith). The use of biological Control agents is one of the most preferable disease management options. Therefore, research should be directed towards identification and efficacy test of biological control agents against the pathogen. Moreover, integration and efficacy evaluation of different management tactics should be done in a way it is environmentally safe, economically feasible and sustainable.
