Ammonium sulfamate is widely used as a herbicide for controlling weeds and unwanted vegetation in non-crop areas such as industrial sites, railways, and roadsides. It is effective against a broad spectrum of plants, including woody species and perennial weeds, due to its systemic action that disrupts plant growth. Additionally, it is utilized as a flame retardant in various materials, including paper, textiles, and wood, to reduce flammability and enhance fire safety. In agriculture, it serves as a defoliant to aid in the harvesting of crops like cotton. Its water-soluble nature makes it easy to apply and effective in various formulations.
