Several diseases were important in the 2016 Nebraska corn crop and impacted yield in some areas. Many of these diseases developed as a result of extreme weather events that were favorable for disease development. Most of those diseases are caused by pathogens that are capable of survival in the crop debris or residue, and so they are more likely to develop again in future years if environmental conditions are favorable again. This article summarizes some of Nebraska’s most important corn disease problems in 2016, tips for diagnosis, and management strategies.
