Evaluation of pre-emergent herbicides for brome grass in barley locations
Aims

To evaluate the performance of several different pre-emergent herbicides and their mixtures on brome infestation in barley.

Key messages
  • Brome grass is increasing in prevalence across southern Australia and control in cereals is heavily reliant on Group B herbicides (sulfonylurea and imidazolinones).
  • Experimental herbicides evaluated in this study were effective on brome (>90% control), but were also unsuitable for barley causing severe crop damage; trials undertaken this season (2017) will focus on wheat.
  • Identifying effective but safe herbicide options for brome in cereals remains a high priority.
