Soybean white mold has been a production problem for soybean producers since early 1990s. White mold outbreaks often occur in even years due to crop rotations, with rare severe occurrences in odd years. Iowa’s cool, wet summer has increased the white mold risk for some growers in eastern Iowa—even though it is an odd year. Extension field agronomist Virgil Schmitt first reported the occurrence of white mold in east central Iowa and Jim Fawcett, northeast Iowa field agronomist, has received a report of severe white mold in a 60-acre field.
