BASF announces EPA approval of Liberty ULTRA herbicide

BASF’s Liberty ULTRA herbicide, powered by innovative Glu-L Technology, has received registration from the U.S. Environmental Protection Agency and is now approved for use, subject to state-level authorizations.

This next-generation herbicide contains the active ingredient glufosinate-P-ammonium, also known as L-glufosinate ammonium, and builds on the legacy of Liberty herbicide, providing an advanced post-knockdown solution for both broadleaf and grassy weeds.

Liberty ULTRA is designed for use on glufosinate-enabled soybean, cotton, corn, and canola acres. BASF highlights the product’s enhanced weed control efficacy, stating it delivers 20% superior performance and has outperformed generic alternatives in nine out of ten head-to-head comparisons.



“As farmers increasingly rely on glufosinate in their weed management programs, the demand for enhanced efficacy and efficiency of this herbicide is more apparent than ever,” said Matt Malone, Product Manager for BASF Agricultural Solutions. “With a narrowing number of effective knockdown tools in the U.S., BASF’s latest innovation, Liberty ULTRA herbicide, will offer American farmers a post knockdown tool that delivers improved performance and convenience thanks to the new Liberty Lock formulation and BASF’s patented Glu-L Technology.”

BASF says Glu-L Technology enhances the herbicide’s active ingredient, allowing it to deliver more power per gallon and cover 33 percent more acres than generics. The formulation improves leaf adhesion and herbicide absorption, resulting in nearly three times the weed penetration compared to other glufosinate-based products. Liberty ULTRA’s efficiency is paired with a lower standard use rate of 24 fluid ounces, providing growers with both convenience and performance.

BASF also emphasizes the product’s ability to tackle tough weeds like palmer amaranth, waterhemp, giant ragweed, and kochia, helping farmers maximize their yields. Liberty ULTRA’s launch sets the stage for additional Glu-L Technology-based herbicides expected from BASF in the near future.
