How to get best results from herbicides: workshops

Northern New South Wales and southern Queensland agronomists are being provided with an opportunity to develop a thorough understanding of how herbicides work, enabling them to provide advice to growers that will optimise the performance of herbicides on-farm.

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, and growers are also invited to attend.

“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 growers 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.”

A number of workshops have already been held across the cropping region this year.

Mark Congreve said the workshops were customised for each location to focus on regionally important herbicides and management issues.

He explained that 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 included:

• Why do herbicides perform or fail in some situations?
• Why do critical comments on the label exist and how were they developed?
• How do adjuvants and water conditioning agents work? What should be used, when and why?
• How does resistance affect different herbicides? What strategies can be used as resistance emerges?
• How do residual herbicides work and what influences their breakdown?

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

GRDC herbicide behaviour workshops will be held at the following locations next month:

• Moree, NSW – October 15 and 16
• Toowoomba, Queensland – October 17 and 18
• Gunnedah, NSW – October 31 and November 1.
