Management Notes (for the Swan NRM Region)
Alternative Names. Rescue grass.
General Biology. Growth form. Grass. Life form. Annual, caespitose. Reproduction. Seed. Dispersal. Contaminated pasture, animal fur. Photosynthetic Pathway. C3.
Notes. Weed of disturbed areas, roadsides, pastures and grasslands. Considerable variation is found between cultivars. Has longevity of 1-2 years. Able to recover from intensive grazing. Heat-tolerant and able to persistent in dry conditions. Requires highly fertile well-drained soils. Awns may penetrate skin of sheep and be a contaminant of wool.
Additional information. Origin. South America. History of use/introduction. Erosion control, animal fodder. Similar native species. Bromus arenarius.
Suggested method of management and control. Prevent seed set for 1-2 years. In degraded areas use 10 ml/10 L glyphosate on seedlings, young plants or when flowering. Alternatively spray plants at 3-5 leaf stage with Fusilade® Forte at 16 ml/10 L or 800 ml/ha (based on 500 L of water/ha) + wetting agent or for generic fluazifop-p (212g/L active ingredient) 10ml/10L or 500ml/ha + wetting agent. Repeat the following year if required. An early and late application may be required where two Bromus species are present. 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.
