Adapted cultivars must have an acceptable level of tolerance or resistance to major insect and disease pests. The European corn borer, ECB, (Ostrinia nubilalis, Hubner) and ear molds (Fusarium spps. in particular F. graminearum Schwabe) are important pests throughout the Northern corn belt of North America. An understanding of the insect, disease and genetic mechanisms of tolerance or resistance have led to the useful Development and application of new and established techniques for developing improved cultivars. Modes(s) of entry, mechanisms of tolerance or resistance, degree of reasonable tolerance vis a vis effects on yield, lodging, grain quality, and source of genetic variability are key long-term steps towards a satisfactory solution.
