These were planted in July. They were not spring plants. It's probably powdery mildew, judging by the white. I will pull them all up by the end of the week. It's only a small section. Is there anything I should do to mitigate it?Fungus diseases are very hard on peas.

Scroll down about half way. The fungi causes must be double anything else. I can't diagnose but if it is pretty white, I call it powdery mildrew. Spots and it's downy mildew.
Keeping the same Spring planted vines beyond mid-July is just about a guarantee of disappointment. Fortunately, sowing seed about then often results in a small crop around first frost.

And I obviously can't compost these, so the trash can they go.Here is a list of resistant varieties. Cornell LINK
I have grown Green Arrow, Oregon Sugar Pod & Super Sugar Snap for years.
No problems if I follow that early/late sowing schedule.
I am only going to much the ones that are not whitish, just in case. I thought it was because of the weather shifts because we had 80 degrees today, and it will snow on Sunday, so the season is over.It isn't a soil borne problem, it tends to be related to high humidity and dry roots, and also the onset of cooler weather. I compost all my vines even in a year where some are affected. That pathogen is airborne. Mulching your vines could help, and I think neem oil is effective against it as well.

I was seriously surprised when I saw the mildew. I know this is specific to this time of year and where I planted the peas. They get too much shade now that the season is turning. It wasn't bad until now, so I nee to treat that bed as a "spring/fall" bed as it just doesn't get the sun the rest of the garden gets. I am still debating what to plant in that spot next year.right, we have so many hosts to powdery mildew around here that it would be impossible for me to prevent it. i don't plant later season peas any more because of how they often get overrun by powdery mildew (and other reasons like i rarely have the time for them with bean harvest season and tomatoes coming on).
