Maybe powdery mildew? #465287

Asked June 25, 2018, 3:43 PM EDT

I think this is powdery mildew on my squash plants. But I’m not sure. Because it is not showing up like circular dustings, it’s very specifically showing up along the veins of the leaf. What is it, and what can I do about it? Help!

Harford County Maryland

Expert Response

The is normal coloration for some varieties of squash plants. We do not see any evidence of powdery mildew. This looks like normal coloration in the plant. It is nothing to worry about.
