Plant Disease Clinic

The Plant Disease Clinic is a service and education function of the Department of Plant Pathology and Environmental Microbiology, and provides clinical diagnoses of plant diseases for approximately 2,000 samples submitted annually by Pennsylvania agricultural producers, urban gardeners, and homeowners.

There is no charge for this service; however, only samples that have been collected from gardens or landscapes within the state of Pennsylvania can be accepted. To submit a sample for diagnosis, please follow the procedures below. If you are located outside of Pennsylvania, please contact the Cooperative Extension Service in your state.
