AHRI researcher, Dr Roberto Busi is no philosopher, but he has recently published some significant research that shows that Aristotle knew a thing or two about herbicide resistance despite being born over 2000 years before the first herbicide. Amazing! The message from this research – never assume that a herbicide mixture will fail even if there is resistance to both components of the mix.

We once thought that the genetics of eye colour was simple. Both parents have blue eyes, therefore, all of their children will have blue eyes. Easy peasy! Then science progressed and we realised that it isn’t actually that simple because several genes are involved. The genetics of herbicide resistance was simple. One parent is resistant to a herbicide, therefore, all of the offspring will be resistant because the gene is dominant or semi-dominant. This is true for almost all cases of herbicide resistance and was easy to understand. Until now. Click to read more about PhD student Jinyi Chen’s research.

Just when we thought we understood the mechanism of trifluralin resistance we blink and find another. Earlier in the year, we reported on research by AHRI PhD student Jinyi Chen confirming that a target site mutation that infers resistance to trifluralin. Earlier in the year, we reported on research by AHRI PhD student Jinyi Chen confirming that a target site mutation that infers resistance to trifluralin. Now Jinyi has confirmed that metabolic resistance to trifluralin is also possible.

Wine and cheese. Strawberries and cream. Crop competition and pre-emergent herbicides.
Ok so the last one doesn’t quite have the same ring about it but they really do go together nicely. Combining a competitive canola variety with pre-emergent herbicides has proven to be an effective strategy for reducing annual ryegrass seed set.
Recent trials showed that with effective pre-emergent herbicides, a competitive hybrid canola variety can reduce ryegrass seed set by 50% compared with a less competitive open-pollinated (OP) variety.
That’s impressive. But should we tar all OP varieties with the same brush?

Can we get away with a single break crop if we throw enough ‘aggressive agronomy’ at a ryegrass population? Are expensive herbicides worth the money? What is better, disc or tyne? Why were the batsmen tampering with the ball, shouldn’t that be the bowler’s job?
These are all questions that were being asked by a local project committee of growers and advisers, and there was only one way to answer them. Enter Tony Swan from CSIRO. He and his team embarked on a massive, long-term research effort in Temora NSW, working with FarmLink to make it happen.
