What are the whitish blotches on my pumpkin leaves?

Asked July 18, 2020, 11:52 AM EDT

Hi MGs, what is causing the whitish blotches on my mini-pumpkin leaves? They're about 3/8 to 1/2 inch across. Kinda furry, like mold, but not like bread mold. Anything to make it go away? It seems to be getting worse.

Clackamas County Oregon

Thank you for your question. Your plants have powdery mildew, which is a fungus, just like bread mold. Here is an article on it and what to do: http://hortsense.cahnrs.wsu.edu/Search/MainMenuWithFactSheet.aspx?CategoryId=5&PlantDefId=55&ProblemId=219 Hope this is helpful. Good luck!
