Can spreading of the soybean cyst nematode be prevented?

It is important to take measures to prevent or slow down spread of SCN to areas where the nematode has not been found. This is especially important in the Red River Valley where SCN was recently introduced, and there are a limited number of infested fields.

If SCN is found in only a few fields in an area or county, the best option is to plant these fields to nonhost crops to slow down spread of the SCN to other fields in the area. Seed contaminated with soil peds from infested fields should be avoided. On farms where both infested and uninfested fields have been identified, farm equipment (Fig. 16) should not be used in uninfested fields until contaminated soil has been thoroughly removed by steam cleaning. While sanitation delays the spread of the SCN, it probably cannot prevent the spread.
