Suggested method of management and control. Prevent seed set. Hand pull plants or spray with Select® 10 ml/10 L (500 ml/ha) prior to boot stage. It is important to minimise bare ground through autumn and winter to suppress annual weed population growth. Read the manufacturers' labels and material safety data sheets before using herbicides.
