Management Notes (for the Swan NRM Region)

Alternative Names. Hairy crabgrass, cockspur, barnyard millet.

General Biology. Growth form. Grass. Life form. Annual, caespitose. Reproduction. Seed. Dispersal. Water, birds especially water birds, other animals, wind. Photosynthetic Pathway. C4. Seedbank persistence. 1-13 years. Fire response. Can rapidly colonise burned areas from soil-stored seed.

Notes. Found in disturbed areas, frequently around water courses where it prefers, wet, fertile alluvial soils. Intolerant of dense shade. Has a fibrous root system. Self-pollinating. Able to grow rapidly and produce prolific seed. Seeds germinate in spring at 18-20°C. Under suitable conditions germination can carry through until autumn. Germination is stimulated by periodic draining and flooding of wetland sites. Root exudates of young plants have allelopathic effects. Herbicide resistance has been recorded.

Additional information. Origin. Europe, India. History of use/introduction. Pasture grass, seed contaminant, erosion control.

Suggested method of management and control. Easily removed by cutting the roots out with a knife or similar. Prevent seed set. Spray Verdict 520® 5 ml/10 L (250 ml/ha) + wetting agent at 3-5 leaf stage up to first tillering. 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.
