The OSU Plant Clinic has officially transitioned to our new 4th floor space in Cordley Hall (we've posted some directions to get you to the right spot). We will be based at our new location during Phase 1 of the Cordley Hall Renovation. Our office phone number and fax will remain the same, but our new mailing address and office is now 4120 Cordley Hall.

About the Clinic

The Oregon State University Plant Clinic is a diagnostic facility that offers fee-based plant disease problem solving and specialized identification services. We also house the OSU Insect ID Clinic, which provides a free insect identification service. Home gardeners are encouraged to first consult with their local OSU County Extension office for free consultations on disease problems.
