Harvest Weed Seed Control

Knowledge level: Advanced

Farm Table says:

This trial is designed to answer an important question; “how can we get the weed seeds in the header?

What is the problem?

Can harvest weed seed practices be adopted to reduce soil weed seed banks in high yielding HRZ areas of the southern region to address herbicide resistance issues?

What did the research involve?

 SFS has commenced researching Harvest Weed Seed Control (HWSC) for the southern high rainfall zone as part of the GRDC funded project.

The project stems across Victoria’s western district and Tasmania, with two paddock scale trials involving the use of commercial equipment to highlight the potential of these management practices. The paddock trial will demonstrate to growers the suitability and effectiveness of a number of harvest weed seed control measures. To complement the large scale trials there will be a trial plot at the SFS Lake Bolac site and one in Tasmania that will put the SFS header through its paces. 

What were the key findings?

The project will measure the suitability of each practice in relation to the efficacy of reducing weed seed bank numbers across a range of weed species and crop types. Regional best management agronomy will be implemented for other control measures as standard across treatments to deliver a functional package to the southern high rainfall zone.
