Stem canker caused by a fungus, can severely create losses in soybean crop yield. Midwestern and north central regions of the United States and Ontario, Canada were plagued by the northern fungus in the late 1940s and early 1950s that was eradicated. Southern stem canker arose in the 1970s and continues to be a significant problem. The northern fungus now appears to have returned.
