Management Notes (for the Swan NRM Region)
Alternative Names. Dutch Clover, Ladino Clover.
General Biology. Growth form. Herb. Life form. Perennial. Reproduction. Primarily seed, also stem fragments, stolons. Dispersal. Wind, water, birds, animals (ingestion), ants. Toxicity. Can be poisonous to mammals. Seedbank persistence. 25+ years.
Notes. Has low germination rates in unsuitable environmental conditions. Physical disturbance and open sites promote seed germination. Annual in warm climates or under moisture stress. Most seed becomes viable after several weeks and can be dispersed long distances by human activities and digestion by animals. The proportion of hard or soft seed depends on conditions during ripening. Has high seed output and forms persistent soil seedbanks. Pollinated by honey bees. Capable of fixing nitrogen.
Additional information. Origin. Northern Africa, Europe, Asia. History of use/introduction. Animal forage, soil improver,. Similar exotic species. Trifolium species.
Suggested method of management and control. Hand remove small/isolated infestations. Otherwise spot spray with 1% glyphosate before flowering or Lontrel® 3 ml/10 L (150 ml/ha) up to 6 leaf stage. 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.
