Abstract

This growing season, diseases caused by Cercospora fungi were widespread in Iowa. There were twoCercospora species, one causing frogeye leaf spot and another causing Cercospora leaf blight. Frogeye leaf spot occurred locally in southern Iowa and Cercospora leaf blight was widely spread throughout Iowa. In some cases, Cercospora leaf blight has been called "sunburn." Because fungi of both diseases can infect seeds at harvest, it is likely that soybean from some fields show seed discoloration, which happened two years ago in northern Iowa. This article addresses the seed quality issue of this fall.
