Oak wilt is a lethal fungal disease that grows in the water conducting vessels (Xylem) of Red, Live and White oak tree families.
Oak wilt is found throughout the central US from Minnesota to Texas and as far east as Western North Carolina
Oak wilt is commonly confused with other oak disorders, but can be diagnosed easily by understanding the symptoms
Most oak wilt is transmitted through roots grafted together under ground from tree to tree
Disrupting root grafts and macro-infusing the fungicide Alamo into the tree are the recommended treatments by the US Forest Service, Texas Forest Service, Texas A&M, University of Minnesota and the other major universities.
