Suggested method of management and control. When soils are moist, hand pull seedlings and small plants ensuring removal of all root material then monitor for 1 year for regrowth; during warmer months, avoiding hot, dry periods, cut or scrape and paint stems - 100% glyphosate; spray regrowth 1.5% glyphosate; drill and fill with 100% glyphosate directly into root crown. Monitor for regrowth Read the manufacturers' labels and material safety data sheets before using herbicides.
