Sunscald on sweet pepper
Detailed guidance for this section is being prepared. Check back soon.
Symptoms on sweet pepper
- ▸ Pale tan to white papery patch on sun-exposed fruit (tomato, pepper, apple)
- ▸ Cracked white patches on south or southwest-facing trunk bark of young trees
- ▸ Affected fruit tissue collapses and often becomes a secondary-rot entry point
IPM controls
- ✓ Maintain healthy foliage cover over fruit (avoid heavy late-summer defoliation that exposes fruit)
- ✓ Whitewash trunks of young fruit trees with diluted latex paint to reduce winter sunscald
- ✓ Site west-facing tomato rows to get morning sun without afternoon sun stress
- ✓ Shade cloth (30-50%) over peppers and tomatoes during heat waves above 95°F
