Powdery mildew on leaves
I've had a few days of rain and now all my squash, cucumber and melon plants have mildew growing. I cut off the leaves as soon as I saw the mildew forming, but now the stems have the mildew on them too. Are there any non toxic means of helping the the plants recover? I have some black futsus forming but the flowers haven't ripened open yet. I'm afraid the mildew will get to them before they ripen.
Most of my squash plants, black futsu, melonette jaspee de vendee are just recovering from SVB and they are already weaken. I'm about to pull out the unproductive ones and plant Autumn glow butternut in their place. These butternuts are supposed to have an 80 day maturity. I've added some mycorrhizal inoculants to the seeds and waiting for them to sprout. So hopefully I will have some squash for winter by mid october. It's normally in the mid fifties here in early to mid october during the day. I've already replanted my marina di chioggia about 2 weeks ago, but I doubt they will be ripe by then. My newly replanted honeyboat squash seedlings were missing this morning. Just their roots were left.
Thankfully I had no squash bugs this year. But the SVBs did quite some damage to my plants.
