Technical Abstract: Pathogens of soybean include a number species of bacteria, fungi, nematodes, oomycetes, parasitic plants, and viruses. Losses due to disease are estimated to be about 14% of total soybean production. Symptoms of soybean plants infected with bacterial pathogens include chlorosis, necrosis, rots, tumors, and wilts. Bacterial blight, pustule, tan spot, wilt, and a few others are reviewed. Symptoms of soybean plants infected with viral pathogens often include leaf mottling and mosaics, rigidity, necrosis, and misshapen and discolored seeds. Important viral diseases of soybean including Alfalfa mosaic virus, Bean pod mottle virus, Soybean mosaic virus, Soybean vein necrosis virus, Tobacco ringspot virus, and Tobacco streak virus are reviewed. Management of bacterial and viral diseases often relies on avoidance, using pathogen free stock (seed), vector control, and resistant cultivars. Future advances to decrease the impact of these diseases will likely include gene-editing technologies and deployment of novel biological control products.
