How to treat Powdery Mildew on African Violets

Zone I live W. of Fort Collins, CO | errhah added on March 23, 2015 | Answered

I have a large number of African Violets and have noticed a powdery substance on some of the leaves of several plants. I think it is probably Powdery Mildew, but how to treat it? How invasive is it? Do I need to isolate the Violets that have it? HELP! Thank you for any advice you can share.

Plants that show signs of powdery mildew should be isolated once they show symptoms of powdery mildew. If left untreated, it will spread. You will want to pinch off the affected areas and discard of them, then apply any of the treatments outlined in the articles below - your treatment options range from organic to chemical:
