Pesticide Damage on Pepper Plants

If all leaves dropped suddenly after spraying an organic insecticide (even for spider mites), the product likely caused phytotoxicity. Peppers are more sensitive than tomatoes. The plants probably won't recover.

Next Steps

• Don't reuse that product.
• Contact the manufacturer—batch issues happen.
• Monitor tomatoes; if they look fine, they're likely safe.

Always test-spray a few leaves first, and apply in early morning or evening to reduce burn risk.
