Management Notes (for the Swan NRM Region)

General Biology. Growth form. Grass. Life form. Perennial, rhizomatous/caespitose. Reproduction. Seeds and rhizomes. Dispersal. Wind, animals, clothing, soil on vehical tyres and machinary, roadside slashing/mowing. Photosynthetic pathway. C4. Seedbank persistence. Possibly less than 12 months. Fire response. Resprouts.

Additional information. Origin. North Africa. History of use/introduction. Ornamental.

Suggested method of management and control. Individual plants can be manually removed. Best controlled as an imature plant, following fire and/or prior to flowering and seed set. Spray with 1% glyphosate. Thick old tussocks may be easier to control if burnt or slashed to 10cm above the ground and allowed to reshoot before applying herbicide. Requires followup. Use unplanned fire to effectively control resprouting plants 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.
