What is wrong with these trees?

[WTNUT]

I attached these pics in another post and I think they were an afterthought with regard to the primary purpose of the thread. Will highlight them here. To me, these trees look damaged, but I am not sure by what or what to do.

Appears to be borers to me. We’re the trees alive this past summer ?...normal growth?

Ummm....I'll jump on the wagon.
I think so too. Borer. Except it looks like the final stage instead of the initial stage. They start with holes about the size of a .38 and that opens up all kinds of possibilities for fungal infections and other insect infestations.

Ever put a dormant oil spay on the trees?

Yes they were, and produced well.

I actually missed oil last year.

When you say final stage that does not sound good! What is the recommendation doc?

Interesting the damage only appears to be on one side of the trees.

That was my first intuition. Could it be frost canker? Is the side that's torn up facing west?

Adults lay eggs in the cambium layer just inside the bark. The larvae feed and grow inside for several years....then they eat their way out to adulthood. If it is borer, all you can do is apply an insecticide in June (I think) to kill the current crop of adults ready to lay eggs. Otherwise, do everything you can to keep the trees healthy and growing faster than the larvae are eating.

Hail damage? April 2014 hail did similar damage to my trees - you can still see the scars.

I was also thinking hail but assumed prop owner would suggest that if it was in a hail storm. I have about a thousand hail damage pics on phone but they're all roofing and sidding lol

 

[SmallChunk]

I say hail or woodpecker damage? Too much damage I would think to be a borer?

Just back on this one because going to work on trees this weekend. Yes, the damaged side of the trees is not he west side.

Not sure if this is the norm everywhere but here in Wisconsin most damaging hail comes from the north or north west. Not always but most often. Any structures on the property? Hail damage is what funds my habitat work lol

Could also be woodpecker damge caused by woodpecker going after borers or other insects.
Could also be Sapsuckers (birds); which will also tap the tree for sap. Usually sapsucker holes are more uniform, though. I don't have experience with borers.
