Technical Abstract: Soybean is the sole domesticated member of the approximately 20 known Glycine spp. It is the most important oilseed crop worldwide. FAO has estimated that 180.4 x 106 t soybeans were produced on 79.7 x 106 ha worldwide in 2001-2003. An average loss of global soybean production due to disease has been estimated at 11% annually. Due to different pathogen distribution patterns, the economic importance of any single soybean disease may vary between geographic areas and seasons. Parasitic microorganisms, such as fungi, phytobacteria, nematodes, and viruses are responsible for the most economically important soybean diseases. The management of soybean diseases caused by microorganisms is the primary focus of this chapter. Although greater than 100 pathogens attack soybean worldwide, relatively few of them cause significant economic damage. This is due to successful disease management practices, including deployment of disease resistance genes, chemical applications, and seed sanitation. All soybean plant parts are susceptible to pathogen attack. The extent of economic plant damage depends upon the pathogen, environmental conditions, host plant susceptibility, stage of plant development, plant stress level, amount of pathogen colonization, and number of plants that are affected. While some soybean pathogens attack multiple plant stages and tissues, specific pathogens and their management will be emphasized in the stage or tissue where they first have a significant economic impact on the growing crop. Information on the causal organism, symptoms, epidemiology, geographic distribution, and disease management practices has been emphasized throughout.
