Glufosinate-ammonium is widely used as a non-selective herbicide to control a broad spectrum of weeds in agricultural fields. It is particularly effective in managing unwanted vegetation in crops that are genetically modified to resist its effects, such as glufosinate-tolerant corn, soybeans, and cotton. This 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 often applied as a foliar spray, making it useful for pre-planting and post-harvest weed control. Additionally, it is employed in orchards, vineyards, and non-crop areas like industrial sites and roadsides to maintain weed-free environments. Its effectiveness against glyphosate-resistant weeds has also made it a valuable tool in integrated weed management strategies.
