Diseases of soybean represent one of the largest yield -limiting factors in Wisconsin. Sudden death syndrome (SDS), caused by the fungus Fusarium virguliforme, has continued to spread across WI and has emerged as one of the top yield-limiting diseases in the U.S. In addition, Fusarium graminearum, the causal agent of Fusarium head blight "scab" on wheat, and ear and stalk rot on com, has recently been shown to cause a new seedling disease on soybean. Although partial disease resistance has been developed for both of these pathogens in soybean varieties, increased incidence has been noted over recent years in commercial germplasm. In addition, the impact of other management practices on Fusarium-induced...
