Check Fields for Soybean Cyst Nematode
Damage due to the soybean cyst nematode (SCN) can reduce soybean yields in Iowa by 50 percent or more, particularly under very dry conditions. And some believe the chances of severe drought conditions occurring in Iowa are greater for 2008 than for any year since 1990. Most of this yield loss can be prevented by growing SCN-resistant soybean varieties in fields infested with the nematode. The resistant soybean varieties prevent SCN population densities from increasing as well as produce profitable soybean yields, thereby preserving the productivity of fields for future soybean production.
