Abstract

Oak wilt is an aggressive vascular disease that typically kills infected trees within 3 to 8 months. It is particularly lethal for trees in the red oak group (section Lobatae). Oak wilt is caused by the fungus Bretziella fagacearum and transmitted over land by sap beetles (Coleoptera: Nitidulidea). Although the disease can be transmitted over land by sap beetles, the majority of oak wilt is spread by grafted roots from other nearby oaks with the infection.
