How Landmark XP Herbicide Works

Landmark XP herbicide contains the active ingredient sulfometuron, a powerful substance that's combined with other ingredients in an easy-to-mix granule. It targets numerous pre- and postemergent grasses and broadleaf weeds, killing the young, developing plants. It mixes in the tank and is applied as a spray to control weeds on turfgrass and other areas. It can also be tank-mixed with other herbicides for even more weed control. 

Where to Use Landmark XP Herbicide

Apply Landmark XP herbicide before weeds develop a strong root system for the best results. Therefore, target weeds that have recently appeared or before they emerge from the soil. Use this herbicide for rangeland restoration and to keep weeds from taking over nonagricultural sites.
