Insect Identification

Proper diagnosis is necessary to achieve good pest management. It's important to remember that only a small percentage of insects on plants are pests.   Check out Common Pests in Landscapes.

Nematode Testing

Nematodes cause roots to become knotted and galled and impair the root system so that water and nutrients cannot be taken up. Nematode damaged plants become stunted, turn yellow and wilt in hot weather.

The best time to determine if you have a nematode problem is in the summer and fall, when nematodes are most numerous.  Nematode Test cost $20.00 each.

Plant Tissue Analysis

Several tests can be performed through leaf tissue analysis. Costs for the tests are dependent upon which test is selected. Results in most cases will be returned in approximately two weeks along with applicable recommendations for any problems discovered.

Plant Identification and Plant Disease Identification

Plant identification is critical for Integrated Pest Management (IPM) and the proper use of pesticides in agriculture and horticulture situations. It is also helpful to the clientele that just want information on that weed, flower, shrub or tree growing in their landscape.

Disease organisms such as fungi, bacteria, and viruses can damage and/ or kill a wide variety of plant materials in Georgia. It is essential to identify the organism accurately before implementing control strategies.

Tips for Submitting Plant Specimens

When possible, collect a generous sample of the plant's stem with leaves still attached. Try to include any flowers, fruits, cones or buds of the plant.  Deliver the specimen fresh to the county Extension Office. Plant samples may not be identifiable if they have been crushed, decayed or dried and shriveled.  To assist in obtaining a rapid, accurate identification of plant specimens, be sure to bring the following information:

  • Description of site where plant was collected. (Sun/shade, natural area/landscape, wet/dry area etc.)
  • Your name and address.
  • Date it was collected.
  • Description of plant (size, shape, description of flowers, etc.).
  • Stage of growth: seedling, blooming, fruiting.
