MSU Extension Plant Diagnostic Laboratory: How Can It Help You?

Did you know the Mississippi State University Extension Service has a laboratory that is designated to diagnose plant diseases and nematodes?

Yes, it does! The Mississippi State University Extension Service Plant Diagnostic Laboratory and its scientists are dedicated to protecting the crops that provide our food and fiber along with other home and garden crops.

As a member of the National Plant Diagnostic Network (NPDN), they are on the lookout for new and emerging plant problems that could affect plant productivity and vigor. The NPDN is a group of internationally respected labs supported by the National Institute of Food and Agriculture, a division of the U.S. Department of Agriculture.

If you’re wondering what nematodes are, they are nearly microscopic, roundworms that feed on plant roots and can impact the growth of crops like sweet potatoes, soybeans, and even home garden vegetables. Testing is the only way to know if nematodes are present and what kind they are. This type of testing  helps producers manage the pests and protect their crops.

Who can use the lab?

• Homeowners and other members of the public
• Commercial businesses
• Research and government regulatory agencies

Testing done at the lab can help you:

• improve plant vigor.
• prevent or manage disease problems.
• be a good steward of the environment.

What diagnostic services does the lab offer?

• Identification of plant disease problems on samples mailed to the lab or from digital images
• Nematode identification and quantification
• Endophyte testing of fescue
• Management recommendations always provided
• Free nematode testing for Mississippi sweet potato growers now through December 31, 2024
• Free nematode testing for Mississippi soybean producers now through March 31, 2025 (or until 500 samples have been submitted to the project)

How do I submit samples?

You’ll need the appropriate sample submission forms. You can get those at your local Extension office or on the MSU Extension website at http://extension.msstate.edu/lab. You’ll also find a list of fees and tips for gathering and submitting samples for testing.
