Field Corn Diseases
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.
