I've been harvesting my Snow Peas and Sugar Snap Peas for more than a month now, and the plants appear to be in good shape.
We've had a few nights of frost about 2 weeks ago; it disturbed many pods, but new, healthy pods are coming up.
Today I noticed the following issues, and I'd appreciate your help in determining what it is and how to handle it:
These unhealthy looking flowers grow upward, with what look like a deformed branch and leaves. I read that this could be a result of virus (https://www.ipm.ucdavis.edu/PMG/GARDEN/VEGES/DISEASES/peavirusdis.html). The pod itself is brown/black; could this be Ascochyta blight?
Leaves and tendrils turn brown and dry.
Brown spots and holes - I couldn't find any aphids, caterpillars or snails. Could this be the frost? I also suspect there is Downy mildew on those yellow-turning leaves. I found some yellow/red growth on the under surface of the leaf.
Shrivelled branch - reminds me of late blight which attacked my tomatoes about 3 weeks ago. Is this Ascochyta blight or just a branch I broke while plucking peas?
My biggest concern is that I'll have to pull out all these plants, especially as they are close to 18 new plants which I planted a month ago - and I don't want them infected too.
