We know that planting date affects soybean diseases and that delayed planting is a useful management tool to reduce the risk of some diseases, especially in regions with a long planting season. However, research by Iowa agronomists shows that early planting increases the possibility of achieving maximum yield and that the level of success decreases as planting is delayed. Because of narrow planting windows for high yield, especially in northern Iowa, the value of delayed planting for disease management is less in Iowa than in other regions with a longer planting season.
