The soybean cyst nematode (SCN) continues to be a serious yield-reducing pest of soybean in Iowa and throughout the Midwest. But damage from SCN is almost always less noticeable in growing seasons with adequate to excess moisture, which much of Iowa experienced in 2008. There can be 30 percent yield loss or more without the soybean crop looking noticeably damaged during the growing season. Very serious soybean yield losses due to SCN are expected the next time Iowa experiences a very dry growing season.
