Suggested method of management and control. Hand remove isolated/small populations. Otherwise apply Lontrel® at 10 ml/10 L + wetting agent before stem elongation in late spring. 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.
