I noticed strange patterns of white appearing on my summer squash leaves a couple weeks ago, it doesnt seem to resemble any online photos of powdery mildew but if it indeed is plz let me know. If its not PM is it another disease? Also for the past week ive seen the vine borrer moths flying around, and was wondering if what im seeing down below on the main stalk is early borrer damage, i dont see any frass at the moment, but the stem is cracking, and i know those darn moths have been around.
