This substance is actually a fungal growth that can spread quickly throughout your garden.
To treat powdery mildew, you can use a fungicide spray or make your own solution using water, baking soda, and dish soap. Mix one tablespoon of baking soda and half a teaspoon of dish soap in one gallon of water and spray on affected plants once a week until the fungus disappears.
