Technical Abstract: Fusarium virguliforme causes soybean sudden death syndrome (SDS) in the United States. The disease was first observed in Arkansas in 1971, and since has been reported in most soybean-producing states, with a general movement from the southern to the northern states. In addition to F. virguliforme, four other species, F. brasiliense, F. crassistipitatum, F. cuneirostrum, and F. tucumaniae, have been reported to cause SDS in South America. Yield losses caused by F. virguliforme range from slight to 100%. Severely infected plants often have increased flower and pod abortion, reduced seed size, increased defoliation, and premature maturity. Foliar symptoms observed in the field are most noticeable from mid to late reproductive growth stages. Research to manage SDS includes studies on crop rotations, soil types, tillage practices, seed treatments, and on the development and utilization of host resistance. This review neither focuses on the other species known to cause SDS outside of the United States nor on other Fusarium species that infect soybean, but do not cause SDS. The last section covers future research in genetic engineering. It is our belief that genetically engineered soybean plants along with other traditional management options will be effective as integrated management technique to control SDS.
