The latest revision of Corn Stewart's Disease, ISU Extension publication PM 1627, is now available. This disease has become a serious issue in Iowa over the past decade, especially for seed producers. A series of warm winters enabled the insect vectors, corn flea beetles, to reach high populations and cause widespread transmission of the disease in Iowa. This publication discusses identification, impact, and management of the Stewart's disease. You may order a single copy of this publication free of charge from the ISU Extension Distribution Center, by calling 515-294-5247. Additional copies are 25 cents each.
