Is a short segment of cane below the wilting leaves dying?

I had foliage on a not so strong 2 year old cane on Sunny Skies begin to subtly change color about a week ago. Foliage started wilting a bit yesterday. Proximal cane looked funny yesterday, and I removed it. Not sure what “did the cane in”, to paraphrase Eliza Doolittle.

Get views from others here - is that a borer hole?

Proximal end of the brown segment looks to be just above the trifurcation point - a tough spot, if you need to cut back.

Verify it does not simply need a drink.

I don't know if that hole is a borer - I looked at other stems where I have pruned and they they don't have a hole like that so maybe it is. Maybe that's what's happening to that stem. I guess I should prune that whole stem off before it does anymore damage - hope it's not too late. Thanks.

Edit - I did water it --

You're in zone 6, has it gotten chilly there again? We went from 73 to 43 in 24 hours here.

Looks like a borer hole to me--I have lots of experience with those. I would cut the cane off below the dark area.Sometimes you end up cutting the !@#$ borer in two in the process. I love to do that. Diane

I’m reminded of Joan Crawford. Mommy Dearest.

Watch out, rifis, or I'm coming after you. Diane

Yep - it's a borer. I read once you have cut the cane down as low as you can, to seal it with white glue. I stuck a long needle down into the cane but don't know if I reached the !@#$ or not. Maybe I did a little damage to it - the cane is very thin -- went as far as I could and then the needle wouldn't go any further. Guess I'll seal it anyway. Maybe the thing will suffocate. ha ha ha....not funny. Thanks to all for thoughts.
