dc.description.abstract <p>Gray leaf spot has become more evident during the past 2 weeks, primarily in eastern Iowa. Lower leaves in some fields have numerous well-developed lesions. So far, ear leaves in most hybrid fields are free of disease or have a few small lesions. Current hybrids are generally less susceptible than they were a few years ago. During the past few years, few hybrid fields in Iowa have had gray leaf spot levels that would warrant a fungicide application. Criteria for fungicide applications in hybrids have relied on presilking disease levels. The corn crop is well past silking, but I have not seen any fields that I feel would have met these criteria.</p>
