Ammonium Salt of Glyphosate 71% SG is a systemic, nonselective herbicide commonly used in non-crop areas such as open fields, bunds, and water channels. It works by inhibiting a critical plant enzyme called EPSPS (5-enolpyruvyl-shikimate-3-phosphate synthase), which is necessary for producing essential aromatic amino acids required for protein synthesis. Without this enzyme, treated plants die due to the lack of protein synthesis.
