Plant Disease and Insect Clinic
North Carolina Cooperative Extension is based at North Carolina's two land-grant institutions, NC State University and NC A&T State University in all 100 counties and on the Cherokee Reservation . North Carolina Cooperative Extension gives residents easy access to the resources and expertise of NC State University and NC A&T State University. Through educational programs, publications, and events, Cooperative Extension field faculty deliver unbiased, research-based information to North Carolina citizens. Cooperative Extension agents can answer your questions on a wide array of topics.
Your County Agent or a Master Gardener can diagnose many common plant disease and insect problems. If necessary, your county agent can help you properly collect and submit a sample to the PDIC, which helps to assure the best diagnosis. After the diagnosis, your county agent can recommend control methods that are suitable to your location and situation.

The NCDA & CS offers analysis of soil nutrients, plant tissues, potting mixes, irrigation water samples, and animal, municipal and industrial wastes. They make recommendations to improve production efficiency and protect natural resources based on sample results.
The Nematode Assay Service can assay soil samples for the presence of at least 46 different plant-parasitic nematodes. A nematode assay can be used to:
- predict a nematode problem on a specific crop for the upcoming season,
- diagnose an existing nematode problem, and/or
- suggest appropriate management strategies.
If we suspect a fertility or nematode problem in your sample, we will refer it to the NCDA & CS at no additional charge to you.
Routine soil and nematode samples should be submitted directly to the Agronomic Services Division of NCDA & CS.
