Photosynthetic Pathway. C4. Seedbank persistence. Possibly produces viable seed, persistence unknown. Fire response. Resprouts.

Additional information. Origin. Tropical Africa. History of use/introduction. First introduced for fodder.

Suggested method of management and control. Dig out small infestations. Slash in winter and/or spray with 1% glyphosate + penetrant in spring to autumn. Follow up treatment until regrowth ceases. Follow-up seedling control. Use unplanned fire events to effectively control any regrowth. 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.
