During the winter, take the time to study your yield maps. They can provide clues for disease management. In this article, we discuss how to manage disease by using a yield map provided by Lyle Stacy of Jefferson County where sudden death syndrome (SDS) has been a problem for years. Yield reduction from SDS damage was evident this past season. Stacy followed SDS development in this field for several years and is working with his client to combat this problem. The yield map (see page 188) of this 55-acre soybean field illustrates a few tips for SDS management.
