Chilean needle grass will become evident in pastures in November-December. Keep an eye out for the reddish purple colour of the seed heads when they first emerge. Each seed has a 7 cm long awn (bristle-like tail). This grass is most likely to be found in pastures on north/west-facing drought-prone slopes but may be present in contaminated stock feed / hay.
If you suspect that you have it, please contact your local council biosecurity people for identification and management advice immediately.
