Aminopyralid

Aminopyralid is a synthetic auxin herbicide. Aminopyralid provides foliar and soil residual weed control, and also increases forage yield in bahiagrass pastures. When present as a soil residue, Aminopyralid causes phytotoxicity, reduced plant height, decreased flower number and fruit yield loss in rotated vegetable crops. Aminopyralid is registered for the control of annual and perennial broadleaf weeds in pastures, permanent grasslands and non-cropped areas^[1]. In Vitro:Aminopyralid (1.4-44.8 g·ae/ha; broadcast to bare soil; single application; 3 weeks prior to planting/seeding) soil residues cause severe, concentration-dependent crop injury and yield loss in sensitive vegetable crops, with substantial harm occurring even at the limit of quantitation (0.2 μg/kg) for soil detection^[1].
