That sounds like canker. I had a big problem with it last year in my potted cherry and peach trees. There is no spray for it. I've read that an increased PH helps as does increased nitrogen in the soil. A fall (before leaf drop) folar application of urea might also help.

Queen,

I think you have two common cherry tree diseases; leave spot and canker.

Myclobutanil brand I use is Immunox made by Spectracide. It also helps with Cedar Apple Rust if you have apples.

Canker is harder. Common practice is to keep a tree healthy (in pot - not letting the tree becomes water- stressed or over-wateried) and cut off cankers branch (if possible)

I attached a link for you to check it out.

below is a link to some pictures from early summer showing the branch die back and leaf spots. The canker type gum and weeping was in late summer. At that point 75% of leaves were probably gone.

So spectracide as leaves emerge seems to be the way to go. What about a dormant spray also?

I agree with others re. dead shoots. It looked very much like an OFM damage. I had it on my peaches but not on the cherry, though.

I spray it with Triazicide Once and Done, also made by Spectracide. OFM may have up to 5 generations in a growing season so you may have to spray a few times starting soon after petal fall (when flowers gone). OFM attacks both fruit and branch tips/shoots.

For leave spot, look for Immunox (I bought concentrated one), not Immunox Plus .
