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.

We thank you for the opportunity to serve you in 2014 and wish you a new year full of health for you and your plants in 2015.

Please note with the extremely cold weather, cold can damage samples during transit, masking the original symptoms. An inexpensive polystyrene cooler keeps cold out as well as in and is a good way to ship a sample in cold weather. If you have any doubts about how to get samples here in the best condition, do not hesitiate to call us at 919-515-3619.
