Interpretive Summary:

Technical Abstract: Soybean cyst nematode, Heterodera glycines, was first discovered in North America in 1954 in Hanover County, North Carolina, USA, when it was found on soybean in a field that had been planted to Easter lilies obtained from Japan prior to World War II. The nematode is now distributed throughout soybean production areas of Canada and the USA, but not Mexico. Annual crop loss 55 years later is reported at approximately 30%. This loss occurs in spite of the availability of resistant cultivars adapted to every maturity group within North America. This paper discusses the history of management of H. glycines and current practices.
