Roundup is a popular herbicide used to control weeds and unwanted plants in agriculture and gardening. Its active ingredient, glyphosate, works by inhibiting a specific enzyme pathway found in plants and some microorganisms, leading to their death. This makes it effective for farmers and gardeners looking to maintain healthy crops and landscapes. Introduced by Monsanto in the 1970s, Roundup has become widely used due to its effectiveness and ease of application. However, its use has sparked debates regarding environmental impact and potential health risks, leading to ongoing research and discussions about its safety and regulation.
