Abstract

Oak wilt, a major disease of oak trees in North America, is caused by a fungus. It infects the sapwood and stops sap flow to the branches, twigs, and leaves. When sap flow is restricted during the growing season, trees wilt and soon die. In addition to killing trees, oak wilt makes it more difficult to export oak logs to other countries. Logs must be free of oak wilt before shipment. However, our knowledge of oak wilt makes it possible to safely export oak logs to other countries without the risk of transmitting the fungus.
