Hardiness Zone: 10a

Many things can cause this. Most likely it is a type of fungus. I would try spraying with fungicide once a week. It also could be bugs. Look under all the leaves for life sucking bugs like aphids and stink bugs and check the stalk for vine bores (little bugs that dig into the plant). You can spray off aphids with a quick spray of the hose and use 7 for most other bugs. As for the vine bores I haven't found any thing that works.
The lower leaves on my squash plants, (winter squash, zucchini, summer) are turning yellow. Does anyone have any experience with gardening that could tell me if this is a water issue or a nutrient shortage or excess? I'm desperate! Thanks so much.

Can you tell me why my zucchini have yellow leaves? If I use the oil will that solve the problem? I have 1130 plants that produce 30 kg. Is that good for the plant?
Please help me. Thank you very much.

We are having a lot of rain here in New England. Is this why my acorn squash is turning yellow (the leaves on the plants)?
