Herbicides are central to modern agricultural practices in Brazil, particularly in the soy, corn, and sugarcane industries. The use of herbicide-resistant genetically modified crops (particularly Roundup Ready soybeans) has been highly significant in Brazilian agribusiness since the late 1990s. In the USA, herbicide use is similarly widespread, though there has been increasing debate about environmental and health impacts, particularly regarding glyphosate-based products. The term is more commonly used in agricultural and scientific contexts than in everyday conversation.
