Fang issued a WeChat message on September 13: We have white spot disease in Chinese cabbage. What kind of medicine is used to prevent and treat it? Cabbage white spot disease occurs in parts of the southern part of the country all the year round, and Chinese cabbage cultivated in spring and autumn is more serious. To control cabbage white spot disease, seeds should be disinfected before sowing; heavy-weight fields should be rotated with melons and other non-cruciferous vegetables to reduce the amount of bacteria; after harvest, field residues should be promptly removed, and the soil should be deeply turned. Cabbage can be grown during the growth period using mancozeb, chlorothalonil and other protective fungicides to prevent. At present, only 70% aluminum-aluminum manganese zinc wettable powders (containing 25% triethylphosphonate and 45% mancozeb) of Limin Chemicals Co., Ltd. (telephone) are registered for the prevention and treatment of leukoplakia in cabbage sprays. The recommended dosage of pure medicine is 1399.95-4200g, about 133-400g per mu. According to relevant reports, cabbage white spot disease can also be treated with difenoconazole, iprodione, azoxystrobin, and boscalid in the early stages of disease. Once every 7 to 10 days, it can be controlled continuously for 2 to 3 times. During the rainy season, Chinese cabbage is best sprayed immediately after the rain, and the control effect is better.
