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.

Citrus fruits include oranges, mandarins, lemons, limes, grapefruits or pomelos. Not only are the citrus fruits delicious and refreshing, but they are also rich in vitamin C, folate, potassium and flavonoids known for their anti-cancer properties. Citrus fruits are the highest value fruit crop in terms of international trade. Around three quarters of the global citrus production is grown in the Northern Hemisphere, particularly in countries around the Mediterranean and the USA.

Compared to some other tree crops, citrus trees have a shallow fibrous root system. As a result, citrus is susceptible to weed competition. As mechanical weed control is expensive and increases the risk of root or trunk damage, majority of farmers choose to use herbicides to prevent weeds from destroying their crops. However, overreliance on a single herbicide can cause resistant weeds to develop.

Glufosinate-ammonium has a key role in sustainable citrus production by controlling weeds and root suckers that would otherwise reduce citrus produce. Thanks to its unique mode of action, the herbicide is registered in many countries for use around young citrus trees, along the crop rows between the grass or legume strips without fear of damaging the citrus trees. It is ideal for use in rotation with other herbicides to mitigate weed resistance. In addition, Glufosinate-ammonium is degraded in soil and cannot move to the roots and up into the shoots.

Did you know?

  • The annual global harvest of citrus is over 110 million tonnes. China itself produces as much as all countries in the Mediterranean region taken together.1
60% of all citrus production is oranges and 23% is tangerines, mandarins, clementines and satsumas. Lemon and limes comprise 12% of the citrus and grapefruit and pomelos - 4%.2

“México es maíz” – y la resistencia a los herbicidas está creciendo

Samuel Sahagún ha cultivado por más de 30 años tierras cerca de Ocotlán, Jalisco. Samuel tiene una granja familiar que heredó de su padre y de su abuelo. En el año 2015, la resistencia de los herbicidas a las malas hierbas se convirtió en un problema. "Fue entonces cuando noté la reducción de la eficacia de los herbicidas convencionales que estaba usando y la necesidad de más cuidado en el control de las malas hierbas", explica. Samuel usa una combinación de diversos herbicidas que contienen diferentes ingredientes activos para abordar el problema de resistencia en su maíz y trigo de invierno. Gracias a la mayor conciencia sobre la resistencia a las malezas y al conocimiento cada vez mayor sobre cómo enfrentar el problema, Samuel Sahagun y sus compañeros agricultores confían en mantener el papel principal de Jalisco en la producción de maíz.

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.
