General Biology. Growth form. Herb. Life form. Annual. Reproduction. Seed. Dispersal. Agricultural activities.
Notes. Mainly germinates in autumn, grows through the winter then flowers in spring, produces seeds and dies off as the soil dries out in early summer. Has low germination rates in unsuitable environmental conditions. Flowers are hermaphrodite (have both male and female parts) and are bee-pollinated. Capable of fixing nitrogen. Trifolium species capable of high rates of nitrogen fixation may influence the abundance and growth of other plant species.
Additional information. Origin. Africa, temperate Asia, Europe. History of use/introduction. Forage. Similar exotic species. Trifolium campestre.
Suggested method of management and control. Spot spray with 1% glyphosate before flowering. Lontrel® 3 ml/10L (150 ml/ha) up to 6 leaf stage. However, best controlled in the seedling stage, as this species is more difficult to control once mature. 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.
