Controlling ryegrass in the southern Mallee locations

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

Key messages
  • 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.
  • BoxerGold was very effective on both sites with added crop safety. This herbicide is expected to be released in 2008 and likely to be expensive but should be included in the crop rotation to reduce the likelihood of developing resistance.
