Crop performance testing results are released annually through the activities of SDSU Extension and the South Dakota Agricultural Experiment Station at SDSU.
View archived reports including data from 2003 - 2017 (when available) in the SDSU Extension Publications Archive.
SDSU Extension will host a crop performance plot tour on July 9 starting at 5 PM CDT at two locations in Walworth County, South Dakota.
Fungicide application in winter wheat has consistently shown to prevent yield loss caused by fungal diseases. However, in some cases, a fungicide application may not always result in a profitable yield when disease pressure is low. Disease forecasting tools can aid fungicide application decisions and hence improve on the profitability of fungicide application.
Crown rust is the most important fungal disease of oats in South Dakota. In years with heavy disease pressure, susceptible cultivars can have over 80% yield loss due to crown rust. The presence of crown rust inoculum on buckthorns can be an indication of the likely risk for crown rust to develop during the growing season. Buckthorns scouted recently were loaded with crown rust inoculum.
