Spray-grazing to remove weeds
Overview
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.
