On Nov. 30, 2023, the U.S. Department of Department of Agricultureﾒs (USDA) Animal and Plant Health Inspection Service (APHIS) announced that it was deregulating Pioneer Hi-Bred International (Pioneer) DP23211 corn.

This corn was developed using genetic engineering to resist corn rootworm and tolerate glufosinate herbicides. After a thorough review, the USDA concluded that DP23211 corn is unlikely to pose a plant pest risk.
