What is Glufosinate-ammonium?

Glufosinate-ammonium is a highly effective herbicide used to control weeds in more than 100 crops in 82 countries around the world. Farmers rely on Glufosinate-ammonium because it ensures a high degree of crop safety, as it only affects the parts of the plant where it is applied. It is effective against a broad range of weeds, eliminating the need to apply several herbicides to control different weeds on a given crop. Its unique mode of action makes it ideal to be used in rotation with other herbicides to mitigate weed resistance.

30 years of safe use

Glufosinate-ammonium was first brought to market in Europe

Glufosinate-ammonium was first brought to market in 1984. Today it is registered for use to control weeds in a variety of crops worldwide, including soybeans, corn, canola and cotton, which have been modified through genetic engineering to be tolerant to Glufosinate-ammonium. As a broad-spectrum herbicide, Glufosinate-ammonium acts against a wide range of annual and perennial broadleaf weeds and grasses. This also includes difficult-to-control Glyphosate-resistant weeds such as amaranthus, lolium, conyza and malva.

Its unique mode of action is a vital tool in weed resistance management, helping to improve crop health, agricultural yields and global food security when used as part of an Integrated Weed Management (IWM) program.

Unlike products with a root systemic mode of action, the herbicide can treat new branches emerging from the roots of a tree (suckers) selectively without harming the mother tree or vine, controlling weeds at the same time. This is of great importance for crops such as vines, tree nuts, stone fruit or olives.

Herbicides
Glufosinate-ammonium is an active ingredient in several non-selective herbicides produced by Bayer CropScience such as Basta®, Finale®, Rely®, and Liberty®.
Fighting Global Herbicide Resistance

Professor Stephen Powles, Director of the Australian Herbicide Resistance Initiative (AHRI), discussed global weed resistance with Liam Condon, Member of the Board of Management of Bayer AG and President of the Crop Science Division, at the Weed Resistance Global Symposium in Paris. Bayer and the AHRI have been collaborating in research on the mechanisms of resistance and continue to exchange experiences in order to develop better solutions that are needed to ensure that weeds do not threaten food production. A diversified approach to weed resistance is needed as herbicides alone as weed control tool are not sustainable. For this purpose, Bayer invests annually more than one billion euros in crop science research and development, combining chemical and biological crop protection products with modern breeding technologies and trait research.

Is Glufosinate-ammonium present in our food?

Any traces of Glufosinate-ammonium that may remain on crops are limited at stricter levels than the defined toxicological safety thresholds.
