Ammonium Salt of Glyphosate 71% SG is a systemic, non-selective herbicide absorbed through green leaves and tender stems. Once absorbed, it moves throughout the plant and inhibits the EPSPS enzyme (5-enolpyruvyl shikimate-3-phosphate synthase), which is essential for synthesizing aromatic amino acids. This blockage disrupts protein formation and growth processes, leading to gradual wilting, yellowing, and death of the entire weed, including roots and rhizomes.
