Reports of European corn borers from across Iowa indicate that populations are very low. Hal Tucker, Tucker Consulting, reported several fields in Monona County in western Iowa with 20 percent of the plants infested. In eastern Iowa, Brad Buchanan, Crop Tech Services, Inc., found a few fields in Cedar County with 20-25 percent of plants with larvae. In central Iowa, Jim Webster, Pioneer agronomist in Reinbeck, noted that his highest counts in Grundy County also were at 20 percent.
