Both seedlings and finished products will be affected. Then the rhizome becomes soft, and finally the whole plant dies. In terms of prevention and control, the methods of selecting strong disease-resistant varieties, selecting suitable planting sites, reducing wounds, reducing bacterial infection and chemical treatment are often used. In chemical treatment, formazan is used. Kitabzin wettable powder, pentachloronitrobenzene powder, thiram, etc., long-term use will not only reduce the efficacy of the medicine, but also affect the surrounding environment
