Prunus - leaf disease?

Our Prunus Kursar planted 3-4 years ago was fine till this summer when about half the leaves, old and new have got this brown spotting and holes. No sign of any insect activity. Any ideas what it is and what to do about it? Thanks!

    It looks like your tree has fungal leaf spot and not as bad as it looks. In severe cases, the leaves may drop prematurely. To break the cycle, get into the habit of raking away fallen leaves around the base of the tree to limit re-infection for next year.
