Notes. Widespread on sandy soils particularly in coastal areas. Can lead to declines in native plant species cover and diversity and make coastal vegetation more susceptible to summer fire. Has staggered germination.
Additional information. Origin. Mediterranean, southern Europe, eastern Europe, northern Africa, temperate Asia. History of use/introduction. Ornamental.
Suggested method of management and control. Prevent seed set. Hand removal small isolated infestations. In selective situations spray with 16 ml/10 L (800 ml/ha) Fusilade® Forte + spray oil or for generic fluazifop-p (212g/L active ingredient) 10ml/10L or 500ml/ha + spray oil any time before flowering. A lower rate of 13 ml/10 L Fusilade® Forte or for generic fluazifop-p (212g/L active ingredient) 8ml/10L can be used in winter at the 2-8 leaf stage before stem elongation. Read the manufacturers' labels and material safety data sheets before using herbicides.
