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.

Pistachios are delicious tree nuts recognized for their nutritional qualities. Pistachio nuts are a rich source of energy, vitamins, minerals, and many phyto-chemical substances with antioxidant properties. Pistachio nut oil features flavorful, pleasant nutty aroma and has excellent emollient features. It helps to keep skin well protected from dryness. Today pistachio trees can also be found in India, Pakistan, Iran, Afghanistan, Tajikistan, Lebanon, Greece, Turkey, Egypt, Italy and the USA.

Pistachio trees are highly vulnerable to weeds that weaken the plants’ resistance to a number of diseases, insects and mites, which can damage entire pistachio orchards. The competition between pistachio and weeds is of greater concern when trees are young because weeds can delay growth and production. Additionally, weeds can host pests and pathogens, interfere with irrigation uniformity and distribution, and reduce harvest efficiency.

Glufosinate-ammonium is a highly effective tool for controlling a broad spectrum of weeds in pistachio trees and has thus enabled a significant increase in yields over the last three decades. The herbicide is applied around the pistachio 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 pistachio.

Pistachios 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
  • Weeds around pistachio trees can be ideal host to the false chinch bug that feeds on the leaves of the trees. In some cases, trees die so rapidly, that scientists belief it injects toxins.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.
