The first report of soybean cyst nematode (Heterodera glycines) in North Dakota was confirmed from samples taken in late 2003. Soybean cyst nematode (SCN) is distributed throughout much of the United States however is still a regulated pest for Canada. This new detection is a concern for growers of soybean and other economically important SCN host crops in North Dakota as well as growers just across the border in Canada. Symptoms of SCN include stunting, chlorosis, and possibly plant death. White or yellow cysts are generally visible upon infected roots.
