triclopyr
Sign in to saveTriclopyr, also Trichlopyr, formally [(3,5,6-trichloropyridin-2-yl)oxy]acetic acid, is an organic compound in the pyridine family of herbicides that is used as a systemic foliar type of herbicide and, secondarily, as a fungicide. Triclopyr is an acetic acid derivative, and so a monocarboxylic acid, with a pyridyloxy substituent: specifically, a pyridin-2-yloxy group substituted by chloro groups at positions 3, 5, and 6. It functions as an herbicide by mimicking the action of the plant growth hormone auxin.
