辣椒疫病是一种毀灭性病害,保护地、露地、辣椒、甜椒,高温多雨区或干旱少雨区均可发病,一般株死率30%-40%,严重时可达50%以上或绝收。本病为土传病害,病菌以卵孢子在土中随病残组织越冬,水流是主要传播途径,兼具土壤和空气传播。病菌主要侵染部位为根茎部,其次是枝杈、叶片、果实,保护根茎部是防治的关键。根据我们三年的试验研究的结果,明确病害发病规律及影响因素,同时制定了一套完整的综合防治措施。
Pepper blight is a devastating disease. Protected areas, open fields, peppers, sweet peppers, high temperature and rainy areas or arid and dry areas can all be affected. The general case fatality rate is 30% -40%, and in severe cases up to 50% . The disease is soil-borne disease, pathogenic bacteria to oospores in the soil overwintering with the disease, the water is the main route of transmission, both soil and airborne. The main infection sites for the rhizome bacteria, followed by twigs, leaves, fruits, protect the roots and stems is the key to prevention and treatment. According to the results of our three-year pilot study, the disease incidence and its influencing factors were clarified and a comprehensive set of comprehensive prevention and control measures was formulated.
