This looks to be one of several bacteria species that cause bacterial spot. This is a very general disease classification, and all have similar treatments. Most will not be cured, fully, but some can be. Either way, they can be managed.

You can try fungicides, but good sanitary practice and keeping all infected debris away from the area.
