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.
