Herbicide behaviour and performance under the microscope at Victorian meetings

Advisers and growers encouraged to register for weed workshops

Victorian agronomists are being provided with further 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.

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

Growers are also welcome to register 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 says.

"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."

Key workshop learnings

A number of GRDC herbicide behaviour workshops have already been held across the southern cropping region this year and the feedback from participants has been positive.

One agronomist commented: "After attending the workshop, I had a much better understanding of herbicides in cropping systems.

"Specifically, I gained additional knowledge on potential situations and conditions resulting in poor herbicide performance, as well as the factors affecting pre-emergent herbicide efficacy."

Feedback from another was: "The content was well presented and comprehensive and will help with explaining herbicide behaviour to my clients. Would be great for growers to attend."

Mr Congreve says knowing what weeds will be controlled from applying a herbicide was relatively easy - as the information was outlined on the product label.

But he says more challenging questions, to be covered in the workshops, 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?

Mr Congreve says the workshops will 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.
