Management Notes (for the Swan NRM Region)

General Biology. Growth form. Grass. Life form. Perennial, stoloniferous/rhizomatous. Reproduction. Rhizomes, stolons. Dispersal. Grazing animals, garden refuse, soil movement. Photosynthetic pathway. C4. Seedbank persistence. Rarely sets seed. Fire response. resprouts.

Notes. Grows rapidly forming dense mats. Favoured as a lawn and pasture species, however can be serious weed of bushland particularly riparian areas. Shades and inhibits growth of herbs and shrubs. Known to release allelopathic substances which impact nearby species.

Additional information. Origin. Tropical eastern Asia. History of use/introduction. Lawn, pasture, soil stabalisation.

Suggested method of management and control. Difficult to manually control as all rhizomes must be removed. Spray with 1% glyphosate or Fusilade® Forte at 16 ml/L + wetting agent or for generic fluazifop-p (212g/L active ingredient) 10ml/L + wetting agent. 2-3 sprays over a single growing season are often required. 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.
