Soybeans are grown worldwide for use in livestock feed, oil, human food, and biofuel. In the United States, 108 million metric tons of soybean were produced in 2014. Soybeans make up 90% of the oilseed produced in the United States and are the largest source of livestock feed protein globally. Soybean grown in the Midwest can be infected by pathogens that cause root rots, foliar diseases and stem diseases. Each soybean disease depends on specific environmental conditions to get established and develop so they may not be a problem each year.
