Benefits for the crop

As a broad-spectrum herbicide highly effective against a variety of weeds, Glufosinate-ammonium has enabled the healthy production of more than 100 crops, including fruits and nuts, canola, soybean and cotton. This has fostered the availability of more high quality and affordable food as well as various products. Farmers also rely on GA when treating young trees as it is a contact herbicide and so can control weeds surrounding trees without harming the tree itself.

As a rich source of protein, used globally in animal feed and food, soybeans yield both solid (meal) and liquid (oil) products. Soymeal is a high quality, in-demand protein ingredient for animal feed for livestock and fish and for protein in foods such as tofu and protein powders. Soy oil has a variety of food applications from cooking oil to margarine and is the primary commercial source of vitamin E in the US diet.

Farmers maintain high soybean yields through effective control of weeds which compete with crops for light, water and nutrients. The use of soybean varieties – bred using GM techniques to be herbicide-tolerant (HT) – in conjunction with broad spectrum herbicides offer one of the most effective means of weed control.

The only broad spectrum herbicides that can be used with HT soybean crops today are Glufosinate-ammonium and Glyphosate. Until recently, only Glyphosate-tolerant soy was available. Insufficient rotation of the herbicidal modes of action in the past has resulted in many weeds in vital soybean growing regions no longer responding to Glyphosate treatment. As such, farmers are increasingly aware of the need to rotate their use of Glyphosate with Glufosinate-ammonium to mitigate weed resistance.

Did you know?

  • Farmers who adopted a “no-tillage” or “reduced tillage” practice after planting herbicide-tolerant soybean varieties saved over 885 million liters of fuel.
Importing Soybeans
The EU is one of the world’s largest import markets of soybean, importing on average 27 – 32 million tonnes per year, while producing only 0.8 million.
Talking Weed Issues Across Continents

Richard Hinchliffe, and English farmer, and Santiago del Solar Dorrego, an Argentinian counterpart, discuss weed resistance with an Argentinian agricultural engineer, Fernando Garcia Frugoni. Even though Argentina and Europe have different agricultural practices, the challenge of weed resistance is common. Both regions discovered that today farmers have to think well in advance about what they are doing and make decisions about crops and rotations for years to come. In both regions, dealing with the problem is all about a "combined integrated approach with herbicides the last part of the puzzle". Cultural methods have to be integrated first before reaching for chemistry as the final piece.

Is Glufosinate-ammonium present in our food?

Any traces of Glufosinate-ammonium that may remain on crops and that are ingested directly by humans or indirectly as a result of consuming meat and milk from animals that have fed on such crops are limited at stricter levels than defined toxicological safety thresholds.
