Richard,

That is either a fungal or bacterial leaf spot disease. The tree will be fine with no need for treatment. Besides it is pretty difficult if not impossible to effectively spray a tree unless you have some special equipment. I would just leave it alone and make sure it is well watered during droughts, especially in summer, and fertilized a little in the spring or early summer.

Thanks for the question. Please stop in again soon!
