2017 Soybean Cyst Nematode Sampling Program (08/31/17)

The NDSU Extension Service and the North Dakota Soybean Council are working together again to coordinate a soybean cyst nematode (SCN) soil testing program. A total of 2,000 SCN soil test bags will be available to growers on a first come first serve basis.

2017 Soybean Cyst Nematode Sampling Program

The NDSU Extension Service and the North Dakota Soybean Council are working together again to coordinate a soybean cyst nematode (SCN) soil testing program. A total of 2,000 SCN soil test bags will be available to growers on a first come first serve basis.

By the end of the first full week of September, each County Extension office should have pre-labeled SCN soil test bags. Participants can pick up to three bags each. Each bag is pre-marked with billing information that will be covered by the North Dakota Soybean Council. To submit a sample, fill the bag with soil, provide site information and send the bag to the partner lab (Agvise). Results will be mailed directly to the growers and the laboratory fees are covered by checkoff dollars to the North Dakota Soybean Council.

This SCN sampling program began in 2013 and has been instrumental in understanding where SCN is located in the state. To date, over 2,200 samples have been submitted by North Dakota growers, and about 1/3 of those have had some level of nematode eggs. The egg levels and geospatial positions from previous years samples that were used to generate SCN distribution maps in North Dakota show ‘hot spots’ in much of the SE and movement west and north (Figures 1 and 2). In 2017, we will use egg level data and add to the map. Importantly, NDSU does not have access to any personal information – just the egg level and geospatial data to generate a map.

We encourage everyone to sample their soil for SCN and thank the North Dakota Soybean Council for funding the effort.
