Glufosinate-ammonium is primarily used as a broad-spectrum herbicide in agriculture to control a wide range of weeds. It is applied to crops such as corn, soybeans, and cotton, especially in fields where genetically modified, glufosinate-resistant crops are grown. The chemical works by inhibiting the enzyme glutamine synthetase, leading to the accumulation of toxic levels of ammonia in plant cells, which ultimately kills the weeds. It is also used in non-agricultural settings, such as for vegetation management in industrial areas, along railways, and in public spaces. Additionally, glufosinate-ammonium is employed as a desiccant to facilitate the harvesting of certain crops by drying out the plants. Its effectiveness and relatively quick degradation in the environment make it a popular choice for weed control in various applications.
