Field Corn Diseases in Illinois

Many corn fields in every county in Illinois develop disease problems every year that affect yield and quality of the grain crop. As history has shown repeatedly, corn diseases can and do periodically cause significant yield losses in patterns that are difficult to predict in advance. Corn diseases typically cause minimal damage over the entire state, however, some acreage suffers significant disease damage each year. Fortunately, corn has effective genetic resistance to many of the important diseases, however, numerous challenges remain in management of corn diseases. This includes the seed and seedling diseases, leaf diseases, stalk diseases, and ear rots. The occurrence of any specific disease depends on environmental conditions, cultural practices, and the hybrid that is grown.
