Evaluation of herbicides for use on Vulpia sp. in barley locations
Aims

To compare the effectiveness and cost of several pre and post emergent herbicides on the control of Silvergrass in Gairdner barley in a replicated trial. 

Key messages
  • Pie-sowing treatments of trifluralin herbicide are effective in increasing yields in a barley crop infested with Vulpia. Application rates of 3.0 1/ha produced a significant result, while application rate of 1.5 1/ha produced a strong trend.
  • No significant differences could be demonstrated between Post-sowing treatments employed in this trial due to large variations between plots. However averaged results indicate trends that can be further explored with more trial work. 
  • For further conclusions please see the attached trial report.
