Brief Project Summary:

Soybean Cyst Nematode (SCN) is an invasive pest that was first identified in North Dakota in 2003. Since then, the pathogen has been confirmed in 12 North Dakota counties. The pathogen can cause approximately 15-30 percent yield loss without aboveground symptoms. When SCN egg levels become high, the disease is very difficult to manage, and yield loss can be devastating. However, management strategies for SCN are available. If growers are proactive, egg levels can be kept low, and yield loss can be minimized. This research and extension project was created to increase SCN awareness among growers in an effort to prevent unnecessary yield loss.

Information And Results
Final Project Results

Attendance at the SCN field days exceeded 100 people, and attendees (29 responding) reported that they were more comfortable understanding the importance of SCN, understanding the importance of SCN sampling and how best to sample, and understanding how to use the tools available to manage SCN after attending the field days.

There were 193 sample bags sent for analysis, of which 81 were positive. Of the 81 positive samples, 36 were considered very low level (200 eggs/100 cc or below as indicated by gray squares) and should be viewed with some caution. (False positives are known to occur.) The highest concentration of positive samples and the highest recorded egg levels were detected in Richland, Cass and southern Traill Counties.

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.
