Nodules on Live Oak trees.

Asked January 9, 2017, 6:57 PM EST

I have Nodules on two of my young live oak trees. It seems to be killing my tree. The leaves are drying up on the ends and working in to the petiole. It may not even the Nodules causing the leaf death. What is this and how can I treat it?
