Suggested method of management and control. Hand pull seedlings and small plants ensuring removal of taproot; for larger vines, sever stems and dig out taproot; scrape and paint using 100% glyphosate or foliar spray with glyphosate 1.5%. Follow up work will be required for 18 months. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
