Butter Squash and Zucchini Disease

[ferice]

I started growing butternut squash and zucchini. I fertilized them with some bloodmeal and fishbone meal. aAlso, we've been getring quite a bit od f rain in zone 10a. a couple days ago, I notice an issue withe the lower leaves. I cut them off, but it's taking over the upper leaves as well. Here are a couple of pics.

It looks like they are staying too wet. Pull back the mulch and help it dry out

We did get some rain here in zone 10a. I stopped watering them after the rain. I am spraying them with a solution of hydrogen peroxide now. Hopefully, they will recover soon.

Staying too wet stops the oxygen for getting to the plant. If you drench the soil with 1 part 3% hydrogen peroxide to 2 parts water it will add oxygen to the soil, plus, it will kill any root pathogens such as root rot if the root rot is not extensive, and yours is not at this time.
