Comparison of pre-emergent herbicides in control of problem weeds in wheat – north-west coast locations
Aims

To compare pre-emergent herbicides in the control of problem weeds in wheat.

Key messages
  • Utilising a pre-emergent herbicide of any kind significantly reduced broadleaf weed establishment overall .
  • Terrain and Terrain + Avadex treatments resulted in highest control of fumitory and cleavers.
  • No significant difference between pre-emergent herbicides on grass and radish control.
  • There was no significant influence of pre-emergent herbicide on yield.
  • Untreated and Sakura treated plots had significantly lower protein levels.
