Management Notes (for the Swan NRM Region)

Alternative Names. Woolly-head clover.

General Biology. Growth form. Herb. Life form. Annual. Reproduction. Seed. Dispersal. Agricultural activities.

Notes. Widely naturalised in valleys of the WA Wheatbelt. Found in lower rainfall areas, most commonly on soils prone to waterlogging. Prefers alkaline soils and has some salinity tolerance. Has low germination rates in unsuitable environmental conditions.

Additional information. Origin. Macronesia, north Africa, temperate Asia, Europe. Similar exotic species. Trifolium species.

Suggested method of management and control. Spot spray with 1% glyphosate before flowering, otherwise spot spray 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.
