Our diagnostic clinic hours will begin on April 4, 2022. Walk-ins will be served Mondays, Wednesdays and Fridays between the hours of 9:00 AM and 12:00 Noon. Specimens may be dropped off during regular business hours 8AM - 5PM, Mon-Fri. All specimens should be bagged. Turf specimens should only be 4" deep X 4" long X 4" wide and have living plants included. Tree specimens should be limited to 12-inch pieces with living portions attached. In consideration of other clients who may be waiting, a limit of 3 specimens will be inspected per visit. 

If preferred, for a small fee, you may send specimens to the Utah Plant Pest and Disease Laboratories in Logan. Please see the links at the bottom of this page for more information.

Volunteers will be available to answer phone calls during the same diagnostic clinic hours above. If the lines are busy, please leave a voicemail message and we will call back as soon as time permits.
