Management Notes (for the Swan NRM Region)

Alternative Names. Purple false brome.

General Biology. Growth form. Grass. Life form. Annual, caespitose. Reproduction. Largely seed, also stem and root fragments. Dispersal. Mammals, wind, vehicles, clothing. Photosynthetic Pathway. C3. Seedbank persistence. Short, less than one year. Fire response. Killed by fire.

Notes. Tolerant of a wide range of habitats. Found growing in sun or shade, in dry or moist areas. Can become dominant in understory vegetation, forming monospecific stands. May limit establishment of native species, and outcompete and completely exclude native herbs and grasses. Has the potential to change fire regimes and to impact riparian habitats. Has high growth rates and able to rapidly complete its life cycle. Certain biotypes have developed herbicide resistance.

Additional information. Origin. North Africa, Mediterranean, temperate and tropical Asia. History of use/introduction. Unknown. Similar exotic species. Bromus species.

Suggested method of management and control. Prevent seed set. Spray in winter with 1% glyphosate. 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.
