Annual broadleaf weeds, if present, reduce the value of sub-clover based pastures for livestock production. Spray-grazing is an effective tactic to reduce weeds, but only if the herbicide and grazing interventions are well managed.

If spray-grazing is carried out correctly, it can lift livestock productivity, while becoming a valuable weed management tool.

Learning objectives

At the completion of this module producers will be able to:

  • understand how to best utilise spray-grazing within their production system 
  • confidently identify the seasonal timing to undertake spray-grazing 
  • understand the risks associated with spray-grazing.
