Glyphosate and aminomethylphosphonic acid (AMPA) residues were extracted using acidified methanol and their concentrations in the samples were determined by a validated liquid chromatography tandem mass spectrometry (LC-MS/MS) method. Glyphosate was detected in R. fruticosus nectar and pollen samples that were taken within a timeframe of two to seven days after the application on the crop as a desiccant.

August 8, 2025 - As a systemic herbicide it is not a true desiccant as it can take weeks rather than days for the crop to die back and dry out after application. Glyphosate works by poisoning the shikimate pathway which is found in plants and microorganisms but not in animals.

December 8, 2022 - Glyphosate and aminomethylphosphonic acid (AMPA) residues were extracted using acidified methanol and their concentrations in the samples were determined by a validated liquid chromatography tandem mass spectrometry (LC-MS/MS) method. Glyphosate was detected in R. fruticosus nectar and pollen samples that were taken within a timeframe of two to seven days after the application on the crop as a desiccant.

November 3, 2017 - Cornucopia’s Take: The industry has long disputed the use of glyphosate as a desiccant, or tried to excuse its use. It is now becoming common knowledge that this practice is exposing everyone who eats conventional foods made from grains to increasing levels of glyphosate residues in food.

November 29, 2021 - Glyphosate is being used as a desiccant on crops like wheat, barley, pulses, and oats (Fleury, 2017). Glyphosate isn’t actually a registered desiccant. Many producers use it as such because it is cheaper and effectively does the same job as ...

The introduction of genetically modified “Roundup Ready” crops—which allow farmers to spray large amounts of the herbicide on their fields without killing the crops—in the mid-1990s dramatically increased its agricultural use, but another lesser known agricultural use of glyphosate is as a pre-harvest desiccant, or drying agent.

1 week ago - Glyphosate is absorbed through foliage, and minimally through roots, and from there translocated to growing points. It inhibits EPSP synthase, a plant enzyme involved in the synthesis of three aromatic amino acids: tyrosine, tryptophan, and phenylalanine. It is therefore effective only on actively growing plants and is not effective as a pre-emergence herbicide.

June 18, 2018 - In the meantime, farmers should not be using glyphosate to desiccate crops prior to harvest, he said. ... “If farmers are using it as a dry-down, then farmers should be changing their practices,” said Dahl. “That’s not what it is registered to be used for.

February 22, 2022 - However, its presence in bread, oatmeal and other products made from oats, wheat, barley, and other Non GMO and organic crops is largely due to its application as a pre-harvest drying agent or desiccant, claims The Detox Project, which says glyphosate-based herbicides are now sprayed on 70+ crops from oats, wheat, and barley, to almonds, apples, dry edible beans, lentils, chickpeas, peas, grapes, rice, and sunflowers, with unknown long-term effects.

May 7, 2024 - It works by inhibiting the production ... to Roundup thrive despite its use. In non-GMO crops such as oats, glyphosate is used for desiccation at harvest to improve both quality and yield....

February 3, 2025 - For food manufacturers to test their products a reference material is recommended to ensure their measurements are accurate. Oats are of particular interest as the herbicide, glyphosate, is used as a desiccant to dry out the crop before harvest.

September 9, 2019 - Events and mounting pressure through the growing season resulted in making this decision,” he said. ... The removal of glyphosate as a desiccant for dry beans follows a trend in other crop sectors where it is discouraged as a desiccant in durum wheat, as well as pulses and other grain crops.

October 28, 2020 - When used as a crop desiccant, the herbicide can be scattered to the soil where it can remain for up to six months (although bacteria in the soil will quickly break it down). Glyphosate also breaks down quickly in food crops, with a half-life ...

This practice has been heavily ... southern U.S. The crops most commonly sprayed with glyphosate as a desiccant are oats, lentils, beans, wheat, potatoes, peas, millet, sugar beats and corn....

December 7, 2022 - Glyphosate and aminomethylphosphonic acid (AMPA) residues were extracted using acidified methanol and their concentrations in the samples were determined by a validated liquid chromatography tandem mass spectrometry (LC-MS/MS) method. Glyphosate was detected in R. fruticosus nectar and pollen samples that were taken within a timeframe of two to seven days after the application on the crop as a desiccant.

September 11, 2025 - Pre-harvest desiccation with glyphosate is a used practice to accelerate maturation and standardize harvest. However, its effectiveness and impacts may vary depending on the dosage, the phenological stage at the time of application, and ...

July 26, 2021 - Harvesting while plants and seeds ... this, some farmers use glyphosate as a desiccant, or drying agent, to kill mature crops and ensure they dry quickly....
