Disease symptoms:
1. Basal lesions: The blight usually causes lesions at the base of the pepper plant first. This may manifest as yellowing, wilting, and wilting of leaves.
2. Stem and leaf ulcers: Orange-brown ulcers may appear on the stems and leaves of the plant. These ulcers may gradually expand and lead to necrosis of the leaves.
3. Fruit rot: If infection occurs on the fruit, it may cause the fruit to rot and brown lesions will appear on the surface.
Approach:
1. Good Drainage: Diseases spread more easily in moist conditions, so ensuring the soil has good drainage is an important step in prevention.
2. Avoid over-irrigation: Avoiding over-irrigation helps reduce moisture in the soil, thereby reducing the risk of disease spread.
3. Fertilize properly: Providing the right amount of nutrients is important for plant health, but avoid overfertilizing, which can cause overgrowth and increase the risk of infection.
4. Crop rotation and intercropping: Avoid planting peppers continuously on the same piece of land. Crop rotation and intercropping can reduce the spread of diseases.
5. Chemical control: When infection has occurred, chemical control using appropriate fungicides can be considered. Please read and follow the instructions on the product label carefully before using pesticides.
6. Select disease-resistant varieties: Selecting disease-resistant pepper varieties is an effective way to prevent diseases.
Early detection and appropriate measures are key to effective disease management. If you notice unusual symptoms on your plants, it's best to take action as soon as possible and ask your local agricultural professional for more specific advice.
