  1. Identify the Mildew: Before taking any action, it’s crucial to correctly identify the mildew affecting your zucchini plants. Powdery mildew is a common fungal disease that presents as white or grayish powdery patches on the leaves, stems, and sometimes the fruits.
  2. Isolate and Prevent Spread: If only specific sections of the plant are affected, consider pruning and removing the affected parts to prevent the mildew from spreading to healthy areas. Be sure to dispose of the removed plant material away from the garden.
  3. Proper Watering Techniques: Avoid overhead watering, as it can promote humidity and create favorable conditions for mildew growth. Instead, water at the base of the plant early in the morning to allow the foliage to dry quickly.
  4. Improve Air Circulation: Ensure proper spacing between zucchini plants to facilitate better air circulation, reducing the chances of mildew development. Trim nearby vegetation or weeds that may obstruct airflow around the plants.
  5. Natural Remedies:
    • Neem Oil Spray: Neem oil is a natural and effective fungicide. Mix neem oil with water as per the manufacturer’s instructions and spray it on the affected parts of the zucchini plant.
    • Baking Soda Spray: Create a homemade baking soda spray by mixing 1 tablespoon of baking soda, 1 teaspoon of mild liquid soap, and 1 gallon of water. Spray this solution on the affected leaves, avoiding excessive spraying on flowers or fruits.
    • Milk Spray: Some gardeners have found success using a milk spray. Mix 1 part milk with 9 parts water and spray it on the zucchini leaves.
  1. Fungicide Application: If the mildew persists despite natural remedies, consider using a fungicide specifically labeled for powdery mildew control on zucchini plants. Follow the application instructions carefully.
  2. Regular Inspection and Maintenance: Continuously monitor your zucchini plants for any signs of mildew resurgence or new growth. Remove affected leaves or treat them promptly to prevent further spread.
  3. Pruning and Proper Disposal: If mildew persists and severely affects the zucchini plant, consider pruning it back to promote new, healthier growth. Dispose of the pruned material away from the garden to prevent recontamination.
