The wet soil this summer has raised some concerns about soybean white mold. After soybean canopies, white mold fungus produces apothecia, tiny mushroomlike structures that produce spores to infect soybean. In recent extension activities such as Iowa State University (ISU) field days, producers wanted information on white mold risk this season and how to scout for apothecia. Some of the more common questions asked are presented below.
