    Product Description

    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.1 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.2 Formulations containing clopyralid have been used as herbicides in agriculture.

    WARNING This product is not for human or veterinary use.
