Buying Guide: Peach Leaf Curl Control And Related Considerations
- What is peach leaf curl and when should I apply treatment? Peach leaf curl is a fungal disease that blights young tissue, causing distorted leaves and reduced vigor. Apply copper-based fungicides as a preventive measure in late winter to early spring, or at first sign of infection, following the product label for timing and frequency.
