Brief Project Summary:

Soybean cyst nematode (SCN) is the most important soybean disease in the United States. Some weeds are known to be hosts of SCN and could contribute to a buildup of SCN in soils. For effective management of SCN it is important to know which weeds will allow the nematode to reproduce on roots. The information from this study will be used in the development of a comprehensive management plan for SCN.

Information And Results
Final Project Results

The conclusion of this research is that the majority of weed species in crop fields in North Dakota are either nonhosts or are very poor hosts of soybean cyst nematode. Only two weeds, henbit and field pennycress, (which are known hosts of SCN), could substantially increase SCN populations in the soil. Pennycress is a common weed in N.D. crop fields while henbit is uncommon.

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.
