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.

Additionally, crops such as canola, corn, cotton and soybeans with the LibertyLink trait are tolerant to Glufosinate-ammonium. Growers are therefore able to apply this herbicide in-crop for non-selective post-emergence weed control, right up to ten weeks prior to harvest, before these weeds jeopardize yield potential.

Few fruits have garnered as much attention in the health research literature as grapes. The combination of unique texture and sweet, tart flavor has made grapes an ever popular fruit. Grapes can be eaten as fresh or processed to create wine, vinegar, raisins, conserves and juice. The world’s largest grape producers include France, Spain, Italy, Argentina, Chile, the USA, Iran, India, Turkey and China.

During the first four years of the vine’s life or where root growth is limited, weeds around the grapevine trunk compete directly with vine growth, and provide a good habitat for field mice or voles, which can girdle and kill young vines. Integrated weed management practices vary considerably from year to year and from vineyard to vineyard. However, key to maintaining healthy and high-yielding vineyards are two tasks: relief of weed pressure and effective vine sucker control without harming the mother tree.

Glufosinate-ammonium is one of the very few products on the market labelled for the control of suckers and a broad spectrum of weeds in one treatment without harming the mother tree. Since it is not possible to control mechanically weeds in steep vine yards, and the alternatives to Glufosinate-ammonium for young vines are very limited, vine farmers have indicated in surveys that they could be forced to give up farming. The distinguishing action of the herbicide helps viticulturist to control weeds with fewer herbicide applications, benefiting farm costs and the environment. Effective weed and sucker control also contribute significantly to higher yields.

Wine Market
According to the 2012 Global Wine Industry Almanac the wine market is forecast to be $303.6 billion by 2016, an increase of 17.9% since 2011.1
  • Glufosinate-ammonium is registered for control of most weed species that threaten the vines. Among them are fat hen, barnyard grass, williow herb, wireweed, and milk thristle.2

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.
