General Biology. Growth form. Herb. Life form. Annual. Reproduction. Seed. Dispersal. Adhesion. Seedbank persistence. 3+ years.
Notes. Germinates mainly in autumn/winter but also in spring/summer if moisture is available. Grows rapidly on fertile soils, enabling it to be competitive with other species. Germination cues depend more on temperature than light. Early germinants emerging in response to summer rain have high mortality compared with late cohorts emerging at the onset of autumn rain, however early cohorts tend to have greater reproductive output. Has self-burying seeds, characterised by a hydroscopic awn, which allows higher seedling survivorship and establishment rates.
Additional information. Origin. Northern Africa, the Mediterranean region, southern Europe.
Suggested method of management and control. Apply Lontrel® at 6 ml/10 L + wetting agent applied before flowering or Verdict 520® at 1.5 ml/ 10 L + wetting agent. 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.
