Description

technical field [0001] The invention relates to a comprehensive control method for clubroot of cruciferous vegetables. Background technique [0002] Clubroot of cruciferous vegetables is a soil-borne disease. The disease was first discovered in the 1970s in Shanghai and in Minhang District in 1993. It is a serious disease in leaf vegetable production in Shanghai. The residual tissue of the root of the diseased plant is left in the field or scattered in the soil. It has strong resistance to the environment and can survive in the soil for 7 to 8 years. When the soil pH is 5.4-6.5, it is suitable for disease. When the pH is above 7.2, the disease will Lighten up. In recent years, with the implementation of the policy of focusing on the production of leafy vegetables in Shanghai, the occurrence and spread of the disease have increased year by year, and the annual spread coefficient is usually 20 times. At present, the annual disease area in the suburbs is about 150,000 mu, acc...
