Sunscald on Peppers is a common issue, particularly in conditions of intense heat and prolonged sun exposure. It occurs when pepper fruits are directly exposed to strong sunlight, causing tissue damage. Here’s a detailed explanation:

Causes of Sunscald:

1. Direct Sunlight Exposure: Fruits that are not shaded by foliage are more vulnerable.
2. Insufficient Foliage: A lack of leaves to protect the fruits can result from diseases, pests, or over-pruning.
3. High Temperatures: Heatwaves significantly increase the risk of sunscald.
4. Improper Watering: Water stress can lead to leaf drop, leaving fruits exposed.

Symptoms of Sunscald:

• Whitish or discolored spots on the fruits, particularly on the sun-exposed side.
• Over time, the affected areas may become dry and brown.
• The tissue in these areas becomes fragile and prone to infections.

Preventing Sunscald:

1. Maintain Healthy Foliage:

   • Use treatments to protect against diseases and pests.
   • Avoid excessive pruning of leaves.

2. Provide Shade:

   • Use shade nets or agrotextiles to reduce sunlight intensity.
   • Ensure proper plant spacing for optimal foliage growth.

3. Proper Watering:

   • Water regularly and evenly, especially during extreme heat.
   • Prevent water stress to minimize leaf loss.

4. Balanced Fertilization:

   • Apply balanced fertilizers to promote healthy foliage growth.
   • Avoid excessive nitrogen, which can reduce foliage density.

5. Choose Resistant Varieties:

   • Select pepper varieties that tolerate high temperatures and are less prone to sunscald.

Managing Affected Fruits:

• Remove Damaged Fruits: Severely affected peppers should be removed to prevent disease spread.
• Reduce Stress: Implement measures like increased watering and mulching to protect the plants.
