Providing research-based information on crop health in South Dakota

The Plant Diagnostic Clinic serves the state of South Dakota and the Great Plains region by providing fast and accurate plant health and diagnostic information for the agricultural and horticultural industries. We perform routine diagnosis of field crop and horticultural crop diseases, and occasionally serve as a point of contact in South Dakota for major agricultural biosecurity issues related to plant health.


Come visit us in our new location Berg Agricultural Hall, Room 203!

Because we receive federal funding, we cannot do any work - samples, photos, or questions - related to medical or recreation cannabis.

SDSU Soybean Cyst Nematode Testing Service

The Plant Diagnostic Clinic is also the SDSU Soybean Cyst Nematode Testing Service. We provide sample analysis and management recommendations to crop managers dealing with the most damaging pest of soybeans in the world - the soybean cyst nematode (SCN). SCN samples are analyzed, free-of-charge, for South Dakota growers thanks to a grant from the South Dakota Soybean Research and Promotion Council.
