Oak Wilt is an aggressive disease that affects all species of oaks (Quercus spp.) found in Minnesota. It is caused by a non-native fungus (Ceratocystis fagacearum) that invades the water vessels of oak trees and eventually kills most infected trees. In the United States, oak wilt is found in most northeastern states and in Texas. In Minnesota, oak wilt is typically found in the southern half of the state. more information
