Sweetbay Magnolia: leaf spotting and turning brown

Hello,
I have a Magnolia virginiana, which is deciduous in zone 7. Last year in mid-summer, the leaves started spotting and turning yellow, then drying out, turning brown and dropping off. This was well before the normal fall leaf-drop. The problem appeared all over the tree and got progressively worse.

This summer the process is starting in the beginning of the summer. (It's late June but we've only have a few hot days so far).

Is this Verticullum wilt? Leaf blight? Leaf spot?
How should I treat it?

It is a beautiful tree that is the centerpiece of my (small) front garden, providing shade and privacy for the front porch... I don't want it to die!!!
