Ralstonia solanacearum is an important phytopathogen which reduces quantity and quality of potato. Due to its wide distribution and broad host range and in soil of different regions through irrigation water or latent infected tubers. It is generally difficult to control the damage of this bacterium. It has widely distributed in most of potato growing regions of Iran and by causing wilt and brown rot disease of potato, is a serious treat for cultivation of this crop in the country. Providing and sowing the healthy and certificated seed tubers is the most effective method of controlling the disease. For a successful strategy of disease management, a clear understanding of mode of disease distribution and epidemiology of causal agent is necessary. In this paper, recent scientific findings on this disease are described and new methods of bacterium detection and health assay of seed tubers are introduced.
