Management Notes (for the Swan NRM Region)
Kate Brown and Karen Bettink, Monday 18 July 2016

Alternative Names. Narrow Clover, Narrow-leaf Clover, White Clover.

General Biology. Growth form. Herb. Life form. Annual. Reproduction. Seed. Dispersal. Sheep (adhesion), agricultural activities.

Notes. Has low germination rates in unsuitable environmental conditions. Seed attached to the fleece of sheep can be transported large distances. Growth is directly related to water availability - under low water availablity growth rate can decelerate but flowering remains unaffected.

Additional information. Origin. North Africa, Macronesia, temperate Asia, Europe. History of use/introduction. Forage, pasture improvement. 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 the 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.
