Grower's Ally Fungicide can help slow the spread of gray mold, but will not cure the disease or repair infected plants / buds. Infected buds need to be removed properly, and the environment (lower humidity, increased airflow...) must be addressed first, before any product can help you. There are many excellent articles that go into great detail about effectively treating gray mold. We wish you the best. **Q: Will this help leaf spots on mountain laurel?** A: If I can sure. **Q: Will this work for peach curl?** A: You must use a copper based fungicide that is specifically labeled for peach or nectarines **Q: Does this work on pachysandra blight** A: Grower's Ally Fungicide will work to help prevent the spread of blight on pachysandra, but it will not repair parts of the plant that are already damaged. We strongly recommend removing diseased leaves and disposing of them properly (and disinfecting your pruning tools). ## Customer Reviews ### ⭐⭐⭐⭐⭐ One bottle cure! *by M***N on June 28, 2026* This product cured my large, long hedge of its powdery mold.
