The prevention and cure points of open-chili pepper disease
1. Seed Disinfection: Before planting, soak the seeds in warm water at 55°C for 15 to 25 minutes, or immerse them in a 72% Previcur solution diluted 800 times for 30 to 60 minutes. Afterward, rinse the seeds thoroughly with clean water and proceed with pre-germination or direct sowing. This process helps eliminate pathogens and improves germination rates. 2. Crop Rotation: Avoid continuous cultivation of peppers in the same area. Instead, rotate with non-solanaceous crops such as cruciferous vegetables, legumes, or cucurbits for a period of three years. This practice reduces the buildup of soil-borne pathogens and enhances overall soil health. 3. Proper Irrigation: Water plants during sunny mornings or evenings, following the principle of frequent but small amounts. Avoid flooding the fields, as excessive moisture can promote disease development. In case of prolonged rain, ensure proper drainage to prevent waterlogging and root rot. 4. Ridge Cultivation with Mulch Film: Use raised beds or apply high mulch film to improve soil aeration and drainage. This method promotes faster seedling growth, strengthens the root system, and increases the plant's resistance to diseases. It also helps control irrigation more effectively, preventing root damage and reducing the risk of root-related issues. 5. Removal of Diseased Plants: Regularly inspect the field for signs of disease. As soon as infected plants are detected, remove them immediately and burn or bury them outside the field. Apply lime powder around the affected areas to disinfect the soil and reduce the presence of harmful bacteria. 6. Chemical Control: Apply a 1:1:200 Bordeaux mixture or 70% Dithane wettable powder diluted 600 times before the onset of the hot and rainy season. Spray every 10 to 13 days to prevent disease outbreaks. Once the rainy season begins, monitor the crop closely and spray early if symptoms appear. Use 58% Metalaxyl-MnZn at 400 times dilution, 40% Benomyl WP at 300 times, or 75% Chlorothalonil wettable powder at 500 times. Apply these treatments to both leaves and stems to effectively manage diseases in sorghum. Suzhou Fangtian Industries Co., Ltd , https://www.fangtianmasks.com
