It's potatoes, not tomatoes, but first came up on this forum, lots of LB threads and if that's what it is, I don't want it to spread to my tomatoes, so I'm posting here.

Thought I had LB on potatoes over a month ago, but since they were still going strong (I did spray a couple of times) I left them and have been harvesting new potatoes for over 2 weeks now. The Red Norlands were looking really ragged, figured I'd dig them all last week, but since we did get rain on Friday I decided to let the rest grow 1 more week (I have been digging on Wed for Fri market). Here's what they looked like last Tues (sorry no closeups), lots of drought stress/dying leaves but since that's an early variety and I planted Mother's Day I just figured their time was up.

The RN are way over on the left, the potatoes in the foreground middle of picture are Pontiacs which are stressed too (been high 90's here and dry all month til Friday).

Anyway, they were crispy, not soggy, no stem lesions so I figured not LB. Today, after more rain overnight (I didn't check them yesterday but they didn't look soggy Sat), stems are pulling right out of the ground, soggy stems, soggy leaves. May just be dead and decaying since I dug new potatoes twice and disturbed the roots too much.

BUT - assuming this is LB - should I dig NOW before more rain tonight, or wait for things to dry out a bit tomorrow and Wed? Also, I plan on throwing all the foliage into garbage bags and getting rid of it, but what about the hay mulch? Don't really want to leave it there (just in case) definitely won't use elsewhere, but would it be OK to compost? Maybe mixed with the horse manure (that hasn't been doing anything) under that blue tarp in the background? That's a LOT of hay to bag up and throw in the trash.

TIA
