Plum tree disease

Question

Bought this plum tree five years ago and it only fruited last year with a nice dessert plum, approximately 12 of them. This year an abundance of fruit. However, see photographs which would appear to be some sort of disease. Is there anything you can suggest please?

Answer 1

I believe this is Plum Pocket disease.

Fungicides can help.
