Common Diseases Affecting Butternut Squash
Before selecting resistant varieties, it’s important to understand the common diseases that threaten butternut squash crops. These include:

- Downy Mildew: Similar to powdery mildew but causes yellowing and browning of leaves, often leading to defoliation.
- Anthracnose: Fungal disease that causes dark, sunken lesions on fruits and stems.
