Oak Wilt

disease3Oak wilt is a disease caused by the fungus Ceratocystis fagacearum that is specific to oaks (Quercus spp.). The fungus is spread through root grafts between neighboring trees and by insects.  Red Oaks are particularly susceptible to oak wilt. The infection causes leaf discoloration, defoliation and death in a very short period of time (from two months to one year).  Fungal mats will form under the bark and force outwards, cracking the bark of the tree.  White oaks are more tolerant of oak wilt infection.  Fungal mats will not form and it will take much longer for the tree to succumb to the disease.  White oaks will show infected annual rings when viewed in cross section.


Initial symptoms of oak wilt will beare browning leaves, beginning at the leaf tip and moving downward and inward toward the stem. As the disease progresses, limbs will die off. . Fungal mats may develop under the bark, pushing the bark out and causing cracks. Untreated, the tree will die, sometimes within a matter of months.
