Windmill grass (Chloris truncata R.Br.), also known as umbrella grass or blow-away grass, is a short-lived perennial species that has recently been identified as resistant to glyphosate. This weed is becoming more dominant in southern Australian farming systems and is steadily encroaching on Queensland. To better manage this key weed, we need to understand its ecology and what management tactics are effective for its control.
