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.

Strawberries, one of the most popular berry fruit in the world, are an excellent source of vitamin C and K, and provide fiber, folic acid, manganese and potassium. The United States is the world’s largest producer of strawberries accounting for 29% of the total world’s strawberry production in 2012, while Spain is the world’s biggest exporter taking up the third of total world export.

Strawberries are however highly susceptible to weed competition, especially when the plants are small and frequent watering provides ideal conditions for weed to grow. Since strawberry plants grow relatively slowly and are poor competitors, weeds quickly invade and establish within bare areas. Strawberry fields are kept in production for several years while weed populations change within the fields, from annuals in the first year to a mixture of annuals and perennials in the following years. The use of herbicides to control weeds is thus an important component of an integrated weed management program.

Glufosinate-ammonium applied between strawberry rows is effective in controlling most grass and broad-leaved weeds and enables a significant increase in yields. Its mode of action as a post-emergence non-selective herbicide that rapidly degrades in the soil allows for treatment after the strawberry plant has grown.

Did you know?

  • The high content of phytonutrients and flavonoids in strawberries makes the fruit red. Flavonoids are also associated with reductions in cardiovascular disease risk.
  • Flowering weeds are especially threatening for strawberries. They are an ideal home to the western flower thrips, a pest that can cause major crop losses.1

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.
