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 acceptance of palm oil worldwide is due to its unique properties that encourage its use in a wide range of end products. In the food industry, palm oil is used as a cooking oil and shortening and in the manufacture of margarine, non-dairy creamers and ice cream. Palm oil produced from the oil palm tree is a main source of income for many farmers in South East Asia, Central and West Africa, and Central America.

In perennial crops like oil palm weeds grow constantly, prompted by the weather and changing seasons. Frequently, outbreaks of weeds occur after a long dry season. This is thus a period when weeding and application of herbicides are carried out more extensively. However, overreliance on Glyphosate has caused serious weed resistance problems in recent years.

The use of Glufosinate-ammonium as an alternative to Glyphosate helps avoid problems of weed resistance in oil palm. Glufosinate-ammonium is a highly effective tool for controlling a broad spectrum of weeds in oil palm and has thus enabled a significant increase in yields over the last three decades. Also, the herbicide can be used to manage weeds in plantations not only to reduce competition to the oil palms, but also to minimize soil erosion and maintain habitats.

Palm oil has now overtaken soybean oil to be the world’s leading vegetable oil. It yields up to 10 times more oil per hectare than rapeseed, soybeans or sunflowers.1
  • A research study on oil palm in Ghana found a very high diversity of weed species - 136 weed species were present in a 50-hectare oil palm plantation.2

Step by Step with Farmers

Agriculture is up against enormous challenges: how to feed a growing world population, the pressure of climate change, and limited natural resources. Innovations in agricultural research and development translate into specific solutions to protect crops from pests, diseases, and weeds. In Latin America, there is more pest incidence and aggressiveness than in other latitudes, which increases the likelihood of pests becoming more resistant. CuidAgro, integrated by government and members of the agribusiness through associations in 18 countries in Latin America, is bringing farmers training courses to help improve their productivity, agricultural practices, and ultimately ensure a more sustainable agriculture. Properly using technologies is a responsibility shared by farmers, distributors, manufacturers, and authorities.

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.
