Triclopyr herbicide is primarily used to kill broadleaf weeds, poison ivy, and woody plants. It’s a selective herbicide, which means that it won’t harm grasses and other plants that don’t fit the classification above. Its main function is to inhibit cell division from the plant’s leaves, resulting in starvation and strangulation. Meanwhile, glyphosate is a non-selective herbicide, which means that it’ll kill any plant species that it’s applied on. Glyphosate works by hindering plant cell division, completely stopping protein production. It also damages all parts of the plants, from roots to leaves.
