Should I reduce the Bt trait acreage in the 2017 corn crop to cut production costs?

The economics of 2017 corn production have challenged many farmers with minimizing losses per acre. One area that some farmers have targeted for reducing costs is hybrid selection. Planting corn hybrids without Bt protection for European corn borer (ECB), corn rootworm or both will greatly reduce seed costs. However, if not careful, farmers could inadvertently reduce crop revenues if they select hybrids without considering yield potential or insect populations in their fields.
