An effective way to manage the soybean cyst nematode (SCN) is to grow SCN-resistant soybean varieties. Resistant varieties can yield well in fields infested with the nematode and can keep SCN population densities (numbers) from greatly increasing. With soybean checkoff funding through a grant from the Iowa Soybean Association, Iowa State University personnel compile an annual list of SCN-resistant soybean varieties available to Iowa farmers. Soybean cyst nematode-resistant soybean varieties in Iowa, PM1649, was recently updated for the 2015 growing season. The 26-page publication is available at no-charge in PDF format online at the Iowa State University Extension and Outreach Online Store.
