Environmental conditions-particulary high temperature and moisture-during seed development, at harvest time, and during storage play an important role in the establishment of microorganisms in soybean seeds. Most of the seed-borne fungal, bacterial, and viral pathogens of soybeans are located inside the seed. These disease agents can reduce seed quality. Pathogens carried in seeds are a source of primary inoculum forthe next season's crop and help distribute the pathogen into areas where it may not be established. Individual seeds in each seed populationmay vary by the type and number of microorganisms carried. Although loss to diseases generally is presumed to be less in irrigated soybeans,certain pathogens may be just as damaging as under nonirrigated cultivation. Some of the diseases reported in soybeans under irrigation are: charcoal rot, stem and root rots, pod and stem blight, downy, purple seed stain, and at least there viruses. All diseases that occur in irrigated soybeans are seed-borne ones, except rust. Thus, measuresto assure that the seed planted is relatively free of seed-borne pathogens is one means of controlling diseases. However, when pathogens such as Macrophomina phaseolina (charcoal rot) are soil-borne and have a wide host range, using seeds absolutely free of the pathogen wil not assure disease control. The control methods for seed-borne pathogens ofsoybeans are nonchemical and chemical. The nonchemical methods includeproper harvesting and storage, handling to avoid injuries, and using..
