The Plant Disease and Insect Clinic, operated by the NC State University Department of Entomology and Plant Pathology, diagnoses plant and insect 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 North Carolina Cooperative Extension, whose county personnel can help identify common problems as well as assist you in properly collecting and submitting a sample to the PDIC.
