Mold On Zucchini Leaves

This is my latest gardening hurdle: there is powdery, grayish mold on many of my zucchini leaves. As it turns out, there are a few simple things you can try to combat this.

First and foremost - never put moldy leaves in your compost. The spores will survive and spread.

As for getting rid of mold on leaves, I was able to find three different organic solutions that can be sprayed directly on the plants to alleviate mold:
  1. Chamomile tea. Make a strong brew and let it cool first before spraying. Chamomile tea is high in sulfur and is a natural fungicide.
  2. Baking soda and water. Mix 1 tbsp of Baking Soda and 1 gallon of water and spray on leaves.
  3. Skim milk and water. Combine at a 50/50 ratio and spray on. This remedy supposedly changes the pH of the surface of the leaves, which prohibits the mold from surviving.

PS - here's a handy link with more remedies for other plant diseases (in addition to mold).
