It is very difficult to control and the plant will look very sorry, even when controls are being used but…
You can try treating the tree with a copper fungicide, starting as soon as temperatures reach about 55F on average in your area. Apply 1-2 times a week for the whole time it is blooming.
Any areas already infected will need to be pruned out. Prune at least 2-3 inches below the infected area. Clean the pruning tool with a 10% bleach solution in between EACH AND EVERY cut.
Even with this, you may not be successful but it is your best option. Good luck!
