How Triclopyr 4 Herbicide Works

Named for its active ingredient, Triclopyr 4 Herbicide provides systemic and foliar activity on broadleaf weeds and woody plants. It contains triclopyr, a compound that mimics the weed's natural growth hormone. As the ingredient races through the weed, it causes uncontrollable growth, thus resulting in the weed's death. It's useful for killing a variety of plants, including poison ivy and creeping Charlie.
