由植物病原细菌Ralstonia solanacerum(Pseudomonas solanacearum)引起的青枯病,广泛分布在热带、亚热带和温带地区,是影响番茄、茄、海椒、烟草、马铃薯等茄科作物生产的重要因素之一。此病是通过土壤传播的较难防治的一种病害。土壤一旦被该病原菌污染,采取土壤消毒、轮作等,也很难抑制其发生。选用抗性品种是最有效的防治方法。 对青枯病有抗性的番茄品种,一般果实品质较差。因此,在日本,番茄栽培大多选择抗青枯病的砧 Bacterial wilt caused by plant pathogenic bacteria Ralstonia solanacerum (Pseudomonas solanacearum) is widely distributed in the tropical, subtropical and temperate regions and is one of the important factors affecting the production of solanaceous crops such as tomato, eggplant, sea cucumber, tobacco and potato. The disease is transmitted through the soil more difficult to control a disease. Once the soil contamination by the pathogen, to soil disinfection, rotation, etc., it is difficult to suppress its occurrence. Selection of resistant varieties is the most effective prevention and treatment methods. Resistant to bacterial wilt of tomato varieties, the general poor quality of the fruit. Therefore, in Japan, tomato cultivars are mostly resistant to bacterial wilt
