What is Oak Wilt Disease?
Oak Wilt Disease is a vascular wilt disease of oak trees caused by the fungus Ceratocystis Fagacearum. The fungus enters the tree and stops the flow of water and elements by plugging the vessels in the vascular system. All species of oaks are susceptible, with some species being somewhat tolerant. The disease is more severe in Red Oak species, such as the Northern Red Oak and Northern Pin Oak. Red Oaks will die rather quickly from Oak Wilt Disease, while White Oaks tend to contain the spread of Oak Wilt Disease to infected branches.
