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 South Dakota for plant and pest diagnostics relating to agricultural biosecurity.
- To be knowledgeable about exotic pests/pathogens that may affect South Dakota
- To serve as first detectors and initiate risk mitigation for threats to the agricultural system in South Dakota
- To serve as an expert plant health laboratory for commercial agriculture and horticulture industries in South Dakota
- To support any department/college teaching and research needs relating to our mission
Statistics/Service Area (cumulative since 2007)
- Samples from 65 of 66 counties in South Dakota and parts of Iowa, Nebraska, Minnesota, North Dakota, Wyoming and Colorado.
- >19,000 client samples (2007–present) received for diagnosis
- Average just over 1500 samples per year
- 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)
- ~10% of submissions relate to horticulture, turf or forestry
