Maximising herbicide performance the aim of GRDC workshops

A workshop designed to provide agronomists with a thorough understanding of how herbicides work and enable them to provide advice that will maximise the performance of herbicides on-farm will be coming to Eyre Peninsula next month.

Grains Research and Development Corporation (GRDC) herbicide behaviour workshops, to be delivered by Independent Consultants Australia Network (ICAN), will address the science underpinning how herbicides work.

“Participants will gain a better understanding of the key factors dictating herbicide performance and what can be done in the paddock to ensure weed control is maximised,” ICAN weed specialist Mark Congreve said.

“Weeds are one of the largest costs to grain producers and herbicide resistance is a key driver of increasing costs.

“When confronted with a range of weed problems and environmental conditions, the challenge is to optimise the results in the field.”

Mr Congreve said knowing what weeds would be controlled from applying a herbicide was relatively easy – as the information was outlined on the product label – but more challenging questions would be tackled.

These include why herbicides perform or fail in some situations; looking at critical comments on the label, why they exists and how they were developed; how adjuvants and water conditioning agents work, what should be used and why; how resistance affects different herbicides and strategies to be used as resistance emerges; and how residual herbicides work and what influences their breakdown.

Mr Congreve said the workshops would be customised for each location to focus on regionally important herbicides and management issues.

The small group workshops will each run for one-and-a-half days and participant numbers are limited to ensure active participation and discussion.

While the workshop content is targeted to experienced agronomists, interested growers are welcome to register.

After stops in Victoria, the workshops will be coming to Eyre Pensinsula in late February.

There will be a workshop at Wudinna on February 26 and 27, then at Cummins on February 28 and March 1.

The cost is $165 per workshop and the events start at 8.30am on the first day and will be finished by lunchtime on day two.
