The EPA issued a final decision to approve Liberty Ultra (glufosinate-P), making it the first herbicide with a label for agronomic crops that follows the principles outlined in the EPA’s Herbicide Strategy, which is intended to help herbicide registrations comply with Endangered Species Act requirements.

The proposed herbicide strategy was released in July 2023 and outlined the EPA’s plan for meeting ESA obligations with respect to herbicide drift, runoff and/or erosion.
