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

The sun rises on crop diversity

Maize (corn) monocultures are a common sight on Hungary’s Northern Great Plain. But as with any monoculture herbicide resistance is always a potential danger. In 2010 Istvan Szolomajer discovered Panicum riparium growing on his fields. Initially, Istvan and his fellow farmers used ALS inhibitors to control this weed, but after several years of application, there was strong evidence of an emerging resistance problem. Istvan’s solution to the resistance problem was to replace maize monoculture with crop diversity – changing from monocot to dicot crops and from spring to winter crops, for example. This year, he has been growing sunflowers on 100 ha, winter wheat on 50 ha, and maize on most of the remaining 200 ha under cultivation. This crop diversity has brought Istvan welcome relief from resistant Panicum riparium. Close cooperation with Bayer staff in Hungary has been a crucial factor in Istvan’s diversity strategy.

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.
