Mode of Action
MSMA, the active ingredient in GAUNTLET®, is a foliar-absorbed herbicide. It accumulates in root and leaf tips, where it rapidly kills leaf and stem tissue. MSMA has multiple sites of action within the plant; however, it is thought to impact on weed growth by interfering with ATP production (energy storage) and cell division (growth process). MSMA is typically more effective on grass weeds than broadleaf weeds. MSMA is generally rainfast within 3 hours of application and has partially systemic properties that allow it to move through the plant. Susceptible weeds generally turn yellow to brown within 3-7 days after MSMA application.
