Plant Pathology Services

Occasionally, diagnosing plant disease requires clinical assistance beyond the local resources available to our Master Gardeners. That's where the Penn State Plant Disease Clinic can help.

For fast and convenient evaluation, we recommend first sending digital photos to PlantClinic@psu.edu. If a more thorough examination is needed, you can also mail physical samples via USPS, FedEx, or UPS. For specific details on submitting physical plant samples, please visit our clinic website.
