Webinar on the management of oak wilt in the Southeast

oakwiltwebinar-previewimageThe Southern Regional Extension Forestry Forest Health Program will host a webinar entitled “The Biology, Diagnosis, Epidemiology, and Management of Oak Wilt in the Southeastern U.S.” on Wednesday, October 26 at 1 pm EST.  This webinar will cover the identification, biology, and management of oak wilt, with emphasis on the southeastern U.S.  Oak wilt is a lethal disease of oaks (Quercus spp.) caused by the fungus Ceratocystis fagacearum.  This disease is prevalent throughout the eastern U.S., and is the most serious on trees in the red oak family (e.g. red oak, black oak, pin oak, etc.).  Ceratocystis fagacearum is an introduced (non-native or exotic) fungus, is transmitted by insects, and can travel through root grafts to infect neighboring trees.  Attendees to this webinar will learn how to identify oak wilt (and distinguish it from similar oak maladies) and what to do once it’s infected a tree.  Management options, including chemical, will be covered.
