Plant Pest Diagnostic Clinic

Washington State University operates two Plant Pest Diagnostic Clinics, in Puyallup and in Pullman. Services of either clinic are available to clients statewide; however, the Puyallup Clinic generally handles samples from western Washington, while samples from eastern Washington are usually submitted to the Pullman Clinic. Both Clinics offer diagnosis of plant diseases and disorders, insect and arthropod identification, and plant/weed identification. Identifications and diagnoses are accompanied by management recommendations when appropriate. Services provided by the WSU diagnosticians are fee-basedThe WSU Clinics are able to process samples from Washington State, but not from other areas of the country. For a listing of Clinics in other states, see Other Diagnostics Resources.

Digital Diagnostics: Clients with PPDeN accounts may submit information and high-quality photos via the Plant Pest Diagnostic eNetwork (PPDeN). Digital sample submission typically allows a more timely response. Digital samples also guide the diagnostician when instructing the client how to submit a physical sample of the plant problem. Those wishing to use PPDeN must have a user account, which may be applied for on the PPDeN website. A webinar on using PPDeN is available here, or may be accessed through the PPDeN website by account holders.
