Prevention and Control
Prevention
- When planting use certified seed or disease free seedlings
- The seeds can be treated to reduce the chance of disease by soaking in hot water (50°C) for 30 minutes before planting
- If the disease is present in the field peppers should be rotated with crops other than tomatoes, eggplants or potatoes for at least three years
- If irrigation is used only water in the morning so the plant can dry before nightfall
Monitoring
- Scout the field once a week checking for symptoms on the leaves and fruits
- Symptoms on the fruits appear as circular dark sunken lesions with concentric rings on the immature and mature fruit
- Lesions can also be seen on the stems and leaves as irregularly shaped brown spots with dark edges
- Consider carrying out early control when more than one lesion is seen on any individual plant
Direct Control
- Remove any diseased plants and fruits from the field and either bury or burn them
