Damage due to the soybean cyst nematode (SCN) can reduce soybean yields in Iowa by 50 percent or more, particularly under very dry conditions. Yet, most of this yield loss can be prevented by growing SCN-resistant soybean varieties in fields known to harbor the nematode. There are hundreds of SCN-resistant soybean varieties available for Iowa growers to plant, and most seed companies do not charge extra for seed of these varieties. In addition to increased soybean yields, SCN-resistant soybean varieties prevent soil SCN population densities from increasing, thereby preserving the productivity of fields for future soybean production.
