Suggested method of management and control. Hand remove all stems in contact with the ground, severe vines at base and leave to dry in canopy then dig out roots; scrape and paint stem - 20-50% glyphosate, alternatively, cut vine at chest height and lie lower sections of the ground before applying 1.5 %glyphosate over them; monitor for 1 year following removal. Read the manufacturers' labels and material safety data sheets before using herbicides.
