Smart speaks with BDN about powdery mildew

Alicyn Smart, assistant professor and plant pathologist at the University of Maine Cooperative Extension and director of the Plant Disease Diagnostic Laboratory, spoke with the Bangor Daily News about powdery mildew. According to the article, powdery mildew can afflict gourds and various plants found in gardens. It interferes with photosynthesis, causing leaves to yellow or die back; and can reduce sugars in fruits and affect their taste. “It looked like somebody walked into your garden with a dough boy and dropped it on your plant,” Smart said. “Typically we see it on the topside of the leaf but we can also see it on the stem of plants as well as in some cases fruit.”
