Description and Uses

Clopyralid is an herbicide that selectively inhibits the growth of the broadleaf weed L. palustris over a panel of 17 New Zealand native non-broadleaf plant species when applied at a concentration of 1.5 mg/L. It does not inhibit growth of human pluripotent stem cells (IC50 = >100 μM) or decrease nuclear translocation of the transcription factor SOX17, a marker of teratogenic risk. In vivo, clopyralid induces brain defects in rabbits, but not rats, when administered at a dose of 250 mg/kg.

Systemic post-emergence herbicide for use in food crops and mesquite.
