Glufosinate-ammonium is a potent herbicide widely used in agriculture and horticulture to combat weed infestations. This article provides an overview of glufosinate-ammonium, its mode of action, application methods, benefits, and considerations for effective and responsible use. Mode of Action Glufosinate-ammonium disrupts the photosynthetic process in plants by inhibiting the activity of an enzyme called glutamine synthetase. This enzyme is crucial for the production of glutamine, an essential amino acid. By blocking glutamine synthesis, glufosinate-ammonium causes a buildup of toxic levels of ammonia in plant cells, leading to cellular damage and eventual plant death. Application Methods Glufosinate-ammonium can be applied using various methods depending on the target weeds and the crops being cultivated: A. Foliar Spray Foliar application involves spraying the herbicide directly onto the leaves of weeds. This method ensures efficient absorption of glufosinate-ammonium by the fo...
