Control: "Stems layer, stumps resprout so followup and control as needed to eradicate. A few seedlings may appear in bared areas. Use herbicide only when roots cannot be pulled.
Physical: Pull roots up (all year round). Cut off above ground or tie stems in air to prevent them coming in contact with the ground and taking root.
Chemical: 1. Cut down and paint stump (all
year round): glyphosate (200ml/L) or metsulferon-methyl 600g/kg (1g/L) or Tordon
Brushkiller (100ml /L) or triclopyr 600 EC (100ml/L) or Yates Hydrocotyle Killer
(500ml/L) or Banvine (200ml/L) or Woody Weedkiller (400ml/L).
2. Spray large masses on ground where roots cannot be pulled (spring-autumn):
Banvine (120ml/10L) or Woody Weedkiller (240ml/L) or triclopyr 600 EC (30ml/10L)
or Yates Hydrocotyle Killer (15ml/L)" (Weedbusters New Zealand).
