Controlling flaxleaf fleabane locations
Aims

To determine the most effective herbicides for controlling Flaxleaf fleabane (Conyza bonariensis).

Key messages
  • Roundup alone will not control Flaxleaf fleabane. 
  • Addition of Surpass and Ally to Roundup provided the most effective control.
  • To avoid the need to use more expensive chemicals and spray more than twice, control fleabane before it begins to elongate (>40cm in height).
