Hello! We planted a peach tree (Elberta Peach; purchased from a reputable vendor in Denver) last summer; it looked very healthy all of last season and produced beautiful fruit. After learning that we lost a young apple tree to fire blight, we checked on the peach and noticed that many of the young, pliable branches are discolored in patches of brown, some with white spots in the middle. A few pictures are attached. On these branches, many of the leaves are stunted and disfigured, although we initially attributed that to the most recent freeze that affected peaches across the state. A few branches are not producing leaves at all, are dark purplish-brown, and look withered and wrinkled like a dried apple skin. Based on an internet search, we suspect that the tree may be affected by cytospora canker, and wanted to ask if you could please 1) confirm/dis-confirm our identification, 2) provide additional insight into what disease may be affecting the peach, and 3) provide advice for treatment options if the tree is not too far gone?
