Brief Project Summary:

This proposal is to address the continued spread of SCN throughout the soybean growing areas in South Dakota in conjunction with increased risk of brown stem rot (BSR) and sudden death syndrome (SDS) diseases of soybean. While SCN continues to be among the most damaging pest of soybean in South Dakota, several other soil-borne diseases are becoming serious considerations for soybean growers in the state.

The SDSU Plant Diagnostic Clinic along with the Extension Plant Pathologist have helped producers to better manage their crop by analyzing soil samples for SCN, designing effective and economical pest management approaches, evaluating and working with resistance traits in commercial...

Final Project Results

In the FY2014, over 1,100 soil samples were analyzed for SCN, providing growers with the status of their soils and recommendations for SCN management for soil samples that were positive for SCN. Two nematicides: Poncho Votivo and Avicta Complete Beans were evaluated in the Beresford SCN demonstration plots, both on susceptible and resistant cultivars. The resistant cultivar kept the SCN population from increasing than did the nematicide seed treatments. Soybean sudden death pathogen isolates have been collected and will be used for further analysis. Presentations were given at various audiences on SCN importance and management.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
