Powdery Mildew: Organic Controls

Organic GreenCure for Powdery Mildew

Chemical controls for powdery mildew range from harmless substances, such as milk and whey, to hardcore synthetic fungicides. It is important to start with your organic options first, let’s take a look at one of our favorite antifungal organic options for powdery mildew, GreenCure.

What Am I Putting on My Plants?

When it comes to fungicides (organic or not), GreenCure is a product that deserves serious consideration. It consists primarily of potassium bicarbonate (which is used in human food), dietary supplements, and antacids.  This active ingredient is similar to baking soda (sodium bicarbonate). While both bicarbonates can be used as a fungicide, studies show that the potassium version is 25-35 times more effective. Not only is it safe for you, it’s also safe for our environment. The USDA, FDA, and EPA all recognize its safety. GreenCure is one of the few fungicides registered for indoor use by the EPA.
