eNews - June 2014


Welcome to the latest NGA newsletter and a snapshot of our Winter 2014 trial activity. This program covers a wide range of themes from nutrition to weed, pest and disease management together with an investigation of the impact on fallow efficiency from increasing stubble loads.
One project where we are looking for support is our harvest weed management activity. Resistant weeds (and weed management in general) are an increasingly high cost component of our farming system. It is important that we fully evaluate a range of non-herbicide techniques to see whether they have a useful fit under our conditions and weed spectrum. The intended approach is to work closely with growers who are already keen to explore these options and provide the methodology and resources to generate some sound data from planned on-farm evaluations.  Please contact Brendan Burton (0428 979 170) if you are interested in being involved.

On the side bar there are links to two recent publications that provide more background to the complexity and issues of herbicide resistance.
We hope you find the information useful.  Once again, if you have any feedback (positive or negative) we would be glad to hear from you.

Ask a WeedSmart Expert

WeedSmart is an industry-funded initiative that promotes the long term sustainability of herbicide use in Australian agriculture.

“How can weeds on my farm be resistant to herbicides I have not used?”
- Roberto Busi, Research Assistant Professor, Australian Herbicide Resistance Initiative, The University of Western Australia.

Weeds with resistance to multiple herbicide groups are becoming increasingly common. The most alarming cases are where plants are resistant to herbicide groups that they have never been exposed to.

AHRI - Turning up Resistance Genes


AHRI have known for some time that P450 genes are involved in metabolic herbicide resistant ryegrass, but had no idea which genes were responsible, or how they were inherited from one generation to the next. 

Until now.
