Technical Abstract: Soybean was first introduced into the United States in 1765 and became widely planted and a major crop less than 150 years later. As the growing area for soybean production has increased so too have the number and severity of diseases. Some diseases have been recently described while others have been known for over 100 years. The economic importance of any one disease may vary from one geographic area to another and from one season to the next. The extent of loss depends upon the pathogen, environmental conditions, and the susceptibility of the soybean variety. Many pathogens can initiate an epidemic only under specific conditions. For example, many pathogens need certain moisture requirements to infect soybean and others require certain vectors in order to be transmitted to soybean. There are more than 200 pathogens or strains of pathogens known to affect soybean, about 50 of these are important economically. All plant parts are susceptible to pathogens including roots, stems, petioles, leaves, flowers and seed.
