How Boulder 6.3 Herbicide Works

Boulder 6.3 Herbicide contains triclopyr, a chemical that mimics plant hormones. After an application, the active ingredient eliminates and prevents weed growth in the target areas. Because of its organic nature, triclopyr breaks down into several different compounds before finally breaking down into carbon dioxide. It's slightly toxic to fish and birds depending on the species but is considered safe to use in the target areas.
