White spots on large maple tree?
I have a very large maple tree (20+ years) that has developed white spots on one large branch. The branch with the spots is dying but the other branches around it are fine. The dying branch does have some new sprouts but most of the leaves are dead or dying. Any idea what this could be? Is there any way I can treat it?

It could be a number of things, including valsa canker, scale or verticillium wilt. Any of these can be fatal if the tree is stressed for other reasons, such as drought. The best thing to do is contact a professional, or if funds are limited, your county extension office, which can help you with a diagnosis (free) and treatment options.
