Glyphosate is one of the most commonly used methods of handling weeds on farms and elsewhere. It is a key part of modern agriculture, to the point that imagining a food system that operates without it is incredibly challenging. Yet, glyphosate is also the subject of much debate.
Glyphosate is an amino acid inhibitor, which means it stops weeds from growing by blocking their ability to produce amino acids, which are the building blocks of proteins. The herbicide is commonly applied to crops, such as corn and soybeans, that have been genetically engineered to be immune to glyphosate's deadly effects.
