PEST ALERT: Sudden Oak Death
National Training Teleconference Information
 The causal agent of sudden oak death (SOD, also known as Phytophthora canker disease), Phytophthora ramorum, was first identified in 1993 in Germany and The Netherlands on ornamental rhododendrons. P. ramorum was isolated in June 2000 from dying trees in California. Since its discovery in North America, P. ramorum has been confirmed in forests in California and Oregon and in nurseries in California, Oregon, Washington, and British Columbia.
