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.

The olive oil is an integral part of the cuisine in many countries available year round, mainly as a savory addition to salads, poultry dishes and, of course, pizza. Recent research has shown that the monounsaturated fatty acid found in olives can help to decrease “bad” cholesterol in blood and blood pressure.

The olive is a species of a small tree found in much of Africa, the Mediterranean Basin from Portugal to the Levant, the Arabian Peninsula and other parts of the world. During the first five years of the olive’s life or where root growth is limited, weeds around the tree trunk compete directly with tree growth, and provide a good habitat for field mice or voles, which can girdle and kill young trees. Gophers in particular are most prevalent where broadleaf weeds, such as field bindweed and perennial clovers, predominate. Integrated weed management practices vary considerably from year to year and from orchard to orchard, depending on local conditions. However, key to maintaining healthy and high-yielding olive orchards are two tasks: relief of weed pressure and sucker control.

Glufosinate-ammonium is one of the very few products on the market labelled for the control of suckers for olives 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 olive orchards, and the alternatives to Glufosinate-ammonium for young plants are very limited, majority of olive farmers could give up their business without the herbicide. The distinguishing action of the herbicide helps growers to control weeds with fewer herbicide applications, benefiting farm costs and the environment. Effective weed and sucker control also contribute significantly to higher yields.

Spain, Italy and Greece are the world top olives producers olives, providing more than 50% of the global supply.1 Italy is also the biggest importer, followed by the USA and France.2
  • In older orchards weeds create colder and more humid conditions for the olive trees. This increases frost hazards, the potential for olive knot and the risk of infection by the peacock spot fungus.

Managing weed resistance with Integrated Weed Management

The cultivation of wheat reaches far back into human history and its importance hasn’t decreased since then. The wheat-grower Gordon Stoner has 12,000 acres of farmland located in the northeastern part of Montana. But farms like Gordon Stoner’s face a huge problem with increasing weed resistance. “Farmers in Montana and in other parts of the US are having a real resistance problem, because they haven’t been diverse enough in their ways of controlling weeds,“ he says. Dramatic yield losses of up to 100% are forcing farmers to now look for solutions, like new herbicides. "Integration of various measures in weed control–with techniques like crop rotation, diversifying herbicidal modes of action and crop seedbed management–is key!” says Harry Strek, the Scientific Director of the Weed Resistance Competence Center and a strong promoter of Integrated Weed Management (IWM).

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.
