I’m very concerned because I found some wild cherries that look heavily diseased close to my orchard. I’m not sure what disease this is
Look like very bad bacterial canker to me.

That’s about as bad as it gets for me because it’s within 10 feet of my carmine Jewell’s. I found it on wild prunus besseyi. I’m going to spray with copper and destroy all the wild cherries and plums I find close by.
Sorry Clark that is no good at all.
I have had difficulty decerning canker from borer damage on cherry trees. You might disect a branch to be sure it is not borer damage. Good luck.

borers? See any frass? See any holes? What cherry tree pests are in your area—wherever that is?

I’m taking a part a branch tommorow. There is so much goo on there right now even though I did not see holes does not mean they are not there. We’ve never had borers in this area but there is always a first time.
Based on it being cherry the odds are extremely high of being canker. One of my young cherries got a really bad canker this summer, not quite as bad as that but it was pretty ugly. I scraped off all the bark down to good wood and it stopped showing any signs but one part has only 1/2" of good bark - it may not make it.
