  1. First, a good sample should represent the range of symptoms that you observe. Symptoms include leaf spots, fruit rots, wilting, yellowing, etc. Plants that are dry or completely rotted are of little use for a diagnosis, so the fresher the sample, the better the chances of a correct disease identification. Collect your samples early in the week. This minimizes the possibility of the sample being held over the weekend at the post office.

  2. The second thing that you can do to help ensure an accurate diagnosis is to provide important background information about the plant. Accurate information is extremely important in formulating a diagnosis and offering control suggestions to you. Please provide this information to your county Extension office, or include the information with the sample if mailing it directly to the Plant Health Clinic. Interested parties may request an account at and fill out the information online. Be sure to include such things as (1) your name, phone number and email address, (2) name of the plant, (3) description of the problem, (4) age of the plant, (5) sun exposure, (6) any drainage issues and (7) any fungicide, weed killers, insecticides and fertilizers used. This information should be as complete as possible to give a clear history and description of the problem. If possible, submit a photograph of the affected area in the landscape, garden or field. Photos are especially useful for lawn or field problems.

How the diagnosis process works

Samples are submitted through county offices, and by walk-in at the Clinic in Fayetteville.

All samples are entered into the Plant Health Clinic's PClinic database. PClinic samples are archived for documentation of individual activity, for later retrieval, and for educational use.
