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.

Almond trees are a particularly popular crop given the high demand for shelled nuts, essential oils or flour. The delicately flavored and versatile almond is available throughout the year to make a tasty and healthy addition to both sweet and savory dishes. The main world’s producers are the USA, followed by Spain, Iran, Italy, Morocco and other countries.

Almond trees are native to the eastern coast of the Mediterranean but are also widely cultivated in southern Europe and California, where environmental conditions promote the rapid and persistent growth of vegetation. Almond orchards may thus be infested with a variety of annual and perennial weeds that can cause problems with nut drying and gathering the crop from the orchard floor.

Glufosinate-ammonium is a highly effective tool for controlling a broad spectrum of weeds in almond trees and has thus enabled a significant increase in yields over the last three decades. The herbicide is applied around the almond trees and even if small amounts land on crop leaves there is minimal to no damage. The use of Glufosinate-ammonium as an alternative to commonly-used Glyphosate helps to avoid problems of weed resistance in almonds.

Almonds are very effective in reducing “bad” cholesterol in blood. Eating about 42.5 grams of nuts a day may reduce the risk of heart diseases.1
  • Two of the most difficult-to-control weeds in almond fields, horseweed and hairy fleabane, can reduce tree height in first-year orchards by 0.3 meters.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.
