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.
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.
- To serve as the main contact in SD for plant & pest diagnostics relating to agricultural biosecurity.
- To be knowledgeable about exotic pests/pathogens that may affect South Dakota
- To serve as first detectors & initiate risk mitigation for threats to the agricultural system in SD
- To serve as an expert plant health laboratory for commercial ag./hort. industries in SD
- To support any department/college teaching & research needs relating to our mission
Statistics/Service Area (cumulative since 2007)
- Samples from 65 of 66 counties in South Dakota and parts of IA, NE, MN, ND, WY, and CO.
- 5206 client samples (2007–2010; average: 1300 per year) received for diagnosis
- Customers include: farmers, ranchers, crop consultants, retail agronomy, cooperatives, and commercial enterprises as well as homeowners and other noncommercial entities.
- ~90% of submissions are crop related (row/grain crops)
