Organic Treatments for Tomato Leaf Diseases

When diseases appear, organic treatments can help control their spread and severity. Here are some effective options:

Neem oil acts as a natural fungicide and insect repellent. Spray it on affected leaves, ensuring full coverage. Repeat every 7-14 days as needed.

Baking Soda Solution

A mixture of baking soda, water, and a small amount of liquid soap can help control powdery mildew and other fungal diseases. Use 1 tablespoon of baking soda per gallon of water and spray on leaves.

Companion Planting

Plant herbs like basil, marigolds, or nasturtiums nearby to repel pests and reduce disease pressure.

Additional Tips for Healthy Tomato Plants

  • Remove and destroy infected leaves promptly.
  • Maintain proper fertilization to strengthen plant defenses.
  • Use organic mulch to retain soil moisture and prevent soil-borne diseases.
