Neem oil has a dual purpose in the vegetable garden as both a pesticide and a fungicide. It works on arthropod pests that often eat your vegetables and plants.
In addition, neem oil also controls common fungi that grow on vegetable plants, including: Mildews
How to Use:
1. Mix the neem oil at the rate of 2 tablespoons (1 ounce) per gallon of water. Mix the solution thoroughly
2. Spray all plant surfaces (including undersides of leaves) until completely wet
(Some plants can be killed by neem oil, especially if it is applied heavily. Before spraying an entire plant, test a small area on the plant and wait 24 hours to check to see if the leaf has any damage)
