The Plant Disease and Insect Clinic diagnoses plant problems for farmers, growers, landscapers, homeowners, and gardeners. In consultation with expert faculty, we recommend ways to treat or prevent the problems we diagnose.

We work in partnership with your local County Agent or Master Gardener, who can diagnose many common plant disease and insect problems, or help you properly collect and submit a sample to the PDIC if necessary.

Many plants suffer during the hot humid days of summer, while plant diseases and insects thrive. We are ready to diagnose your plant problems. Navigate to "How to Submit a Sample" if you need our help.
