Learn to boost weed control

By Country News

Gaining a greater understanding of how herbicides work and optimising performance of herbicides on-farm will be the focus of a number of upcoming agronomist workshops.

The Grains Research and Development Corporation herbicide behaviour workshops, to be delivered by Independent Consultants Australia Network, will address the science underpinning how herbicides work, and growers are also welcome to register to attend.

ICAN weed specialist Mark Congreve said the key factors dictating herbicide performance and what could be done in the paddock to ensure weed control was maximised would be the focus.

‘‘Weeds are one of the largest costs to grain producers and herbicide resistance is a key driver of increasing costs,’’ Mr Congreve said.

‘‘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, but more challenging questions include why herbicides performed or failed in some situations, how adjuvants and water conditioning agents worked and when they should be used, and how resistance affected different herbicides.

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

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

The cost is $165 per workshop, which start at 8.30am on day one and finish by lunchtime on day two.

Workshops will be held in Bendigo from July 22 to 23, and Swan Hill from September 17 to 18.
