Pre-emergent herbicide options for controlling ryegrass locations
Aims

To investigate pre-emergent tifluralin mixes for the control of Group A resistant ryegrass.

Key messages
  • Group A resistant ryegrass populations are becoming more prevalent across south Australia, increasing the reliance on the use of Group D (trifluralin) for ryegrass control.
  • Group D resistance will develop if trifluralin is consistently used without other control practices.
  • Trifluralin used in combination with other herbicides such as Avadex Xtra (Group E) and Dual Gold (Group K), may enhance ryegrass control and could prolong the onset of Group D resistant ryegrass populations.
