I just found out these damages on both type of trees, peach and asian pear. How do I treat them? I hope not to cut the branches off, particularly bad on the peach…
Hail damaged? Cicadas damaged?
Gummosis?
Scab?
I do not think it is insect damage, scab, gummosis, etc. I would buy a mild copper product from Lowes or Home Depot and spray on the bark only. I used this on canker and it seemed to work. There may be better choices …

Thanks for feedback, everyone. I’ll buy the copper fungicide to deal with this problem. It’s almost bloom time now, should I wait?
