The Oregon Department of Agriculture and Oregon State University?EUR??,,????'???s Botany and Plant Pathology program have announced the results of lab tests of infected plant material (Phytophthora ramorum) found at a nursery in Gresham, Oregon. The strain is identical to a type found in Europe. The evidence suggests this is an isolated incident, and did not result from the uncontrolled spread of the pathogen from California. "The finding effectively rules out the possibility the pathogen spread by natural means from California," asserted John Aguirre, executive director of the Oregon Association of Nurserymen. How the European pathogen made its way to a nursery in Gresham is unknown.
