NEW! Corvid-19 Sample Submission Guidelines


The Plant Clinic is devoted to our clients and will remain operational until further notice. For the safety of all involved, we request that packages be sent via mail or express delivery if at all possible. Please send us the shipper and tracking number if you ship via an express delivery service so we can track packages and ensure they are delivered quickly from our central University mailing service. If samples are too large to be delivered, please drop them off, with a completed sample form at the West or North loading dock of Cordley hall (map view). Please call us (541-737-3472) to let us know a sample had been dropped off, and we will come get it.

Samples can only be accepted from 10:00 a.m. to 4:00 p.m. on weekdays. Please allow extra time for sample processing.

These measures are being instituted to be in agreement with the University's policies, and to keep our customers and employees safe.  

Directions to the OSU Plant Clinic

From Interstate 5:

  1. Take the Hwy 34 West exit; it is about 5 miles south of Albany. Travel west on Hwy 34 and cross the bridge into Corvallis.
  2.  Continue straight ahead (the road becomes one-way and is called Harrison). Continue on (stay in the left lane) until 30th street. Turn left (south) onto 30th and proceed to Orchard Street (about 3 blocks). Turn left again and drive past the glass houses. The houses terminate in a large brick building, which is Cordley Hall.
  3. Drive into the parking lot between the glasshouses and Cordley Hall. Next to the loading dock there is a sign that says “parking for service labs”. You can pull into that space and come up to room 4120 for a temporary parking permit.
  4. The Plant Clinic is upstairs in room 4120. Enter the building from the loading dock door, then take the elevator (at your left) to the 4th floor. There are signs posted to direct you, but you will go right to the the end of the hall, then left to the end of the hall, and then turn left. The Plant Clinic will be down the hallway on the right at 4120.
