Oregon State University Plant Clinic

National Plant Diagnostic Network

In 2003 the Plant Clinic became part of the newly established National Plant Diagnostic Network (NPDN ), and shortly thereafter it was designated an expert laboratory for the Western Region of the NPDN. As such the Plant Clinic serves as a resource lab and conducts specialized tests for Oregon, Washington, Idaho, and Alaska.

As a result of the Agricultural Bioterrorism Act there has been established a list of organisms of particular concern to the US as a whole. In conjunction with that list ("Select Agents"), the western region of the National Plant Diagnostic Network has established a list of organism of concern to the western region.  The organisms on both lists are described here with the intention of providing a quick means of identification. If you think you may have seen one of these diseases or pests, please contact your nearest participating laboratory in the National Plant Diagnostic Network. In Oregon please contact the Oregon State University Plant Clinic. These fact sheets are for informational purposes only.
