Radon Testing

High radon levels in Georgia counties

Radon occurs naturally when uranium breaks down to form radon. Uranium is often found in high concentrations in granite rocky soils, as are common in northern Georgia counties. As radon is released into the soil, it can enter buildings through the foundation and well water, eventually building to dangerous levels.

Radon kills nearly 21,000 people each year, more than 800 of them in Georgia, and is the second leading cause of lung cancer in the United States after tobacco smoke. Smokers are at an even higher risk of radon-induced lung cancer than nonsmokers.

Test for radon in your home

Make sure your home is safe by ordering a test kit online or by mail for only $15! This price includes shipping, lab processing, and follow up service for testers with elevated results. (Non-Georgians should visit the EPA for assistance assessing radon risk.)

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.

Nematode TestingNematode worm

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.


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, bring the completed Plant Pathology Form with the sample. You will need the following information:Coneflower

  • 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.

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.

Instructions on collecting samples for identification can vary depending on the issue. Please contact our office for more information.

Samples identified in office are free of charge. Samples that are shipped to the UGA Lab are subject to a $10 fee plus shipping.
