Aminopyralid（Cat No.:R057254）is a selective systemic herbicide belonging to the pyridine carboxylic acid family, with the molecular formula C₆H₄Cl₂NO₂. It is primarily used to control broadleaf weeds, including thistles, clovers, and knapweeds, in pastures, rangelands, and non-crop areas. Aminopyralid functions by mimicking natural plant hormones (auxins), disrupting plant growth and causing cell death. It is highly effective at low application rates and is absorbed through leaves and roots. Known for its persistence in soil and manure, aminopyralid requires careful management to prevent unintended crop damage through residue carryover or compost contamination.
