Comparative Susceptibility of Plants Native to the Appalachian Range of the United States to Inoculation with Phytophthora ramorum

R. G. Linderman, P. B. de Sá, and E. A. Davis

September 2007


Phytophthora ramorum, cause of sudden oak death of trees or ramorum blight of other plant species, has an ever-increasing host range. The authors collected foliage of a range of plant species native to Appalachia in Kentucky during two summer seasons, and the foliage was shipped to Oregon for inoculation with P. ramorum to determine relative susceptibility. These results provide a basis for regional surveyors to select target hosts and to generate survey and management practices for nursery and forest areas.
