Description

Prior to 2004, foliar diseases were not a concern in soybean production in Iowa and much of the north central region, except for seed production. Since the report of Asian soybean rust, caused by Phakopsora pachyrhizhi, in South America in 2001 and then in the United States in 2004, fungicide applications became of interest to some producers. Interest has increased recently as soybean prices increased. The use of fungicides to control soybean foliar diseases has been a hot topic. Surveys of the literature show a disagreement among researchers, university extension recommendations and industry applications.
