When pruning your oak trees insure that equipment is sterilized & wounds painted.  A cheap black spray is best, as it seals and allows the wood to cure properly. For your peace of mind, insist that your tree service complies as well.

Root Grafts
Root graft transmission is the most common mode of infection.  Over 90% of all new oak infections are transmitted in this manner.  A root graft is formed when the roots of the same species meet and fuse together.  The disease is then able to move from the infected tree into the uninfected tree.
