Also known as Phosphonomethylglycine, N-(phosphonomethyl)glycine

Glyphosate (IUPAC name: '''N-(phosphonomethyl)glycine') is a broad-spectrum systemic herbicide and crop desiccant. It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSP). Glyphosate-based herbicides (GBHs) are used to kill weeds, especially annual broadleaf weeds and grasses that compete with crops. American agricultural company Monsanto brought it to market for agricultural use in 1974 under the trade name Roundup''. Monsanto's last commercially relevant United States patent expired in 2000.

AI overview

Glyphosate is a widely used weedkiller that works by disabling a key plant enzyme, allowing it to kill a broad range of weeds and grasses that interfere with crop growth. Originally introduced by Monsanto in 1974 under the brand name Roundup, it has become a common agricultural chemical since its patent expired in 2000.

Glyphosate (IUPAC name: '''N-(phosphonomethyl)glycine') is a broad-spectrum systemic herbicide and crop desiccant. It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSP). Glyphosate-based herbicides (GBHs) are used to kill weeds, especially annual broadleaf weeds and grasses that compete with crops. American agricultural company Monsanto brought it to market for agricultural use in 1974 under the trade name Roundup''. Monsanto's last commercially relevant United States patent expired in 2000.

Farmers quickly adopted glyphosate for agricultural weed control, especially after Monsanto introduced glyphosate-resistant Roundup Ready crops, enabling farmers to kill weeds without killing their crops. In 2007, glyphosate was the most used herbicide in the United States' agricultural sector and the second-most used (after 2,4-D) in home and garden, government and industry, and commercial applications. From the late 1970s to 2016, there was a 100-fold increase in the frequency and volume of application of GBHs worldwide, with further increases expected in the future.
