Alright stop, collaborate and listen. Busi’s back with a brand new invention. Something grabbed a hold of him tightly, testing resistance daily and nightly. Will he ever stop? I don’t know! Turn off the lights and he’ll glow. Testing was a problem, Busi has solved it. Check AHRI insight while my DJ revolves it.

Some recent AHRI research by Chinese research student Ci Sun, and Dr Mike Ashworth and others has investigated some early flowering wild radish and found that it does indeed set its seed below the harvest height. But we can ‘adapt and overcome’ to this new genetic trait by increasing crop competition.
AHRI researchers have identified a new glyphosate resistance mechanism which has similarities to cancer drug resistance in humans.
We’re blowing up our most valuable herbicides on the least productive part of the farm. Fencelines, roadsides, drainage areas, etc. AHRI researchers, Dr Yaseen Khalil and Dr Mike Ashworth and others have confirmed the world’s most recent addition to the growing list of glyphosate resistant weeds: capeweed.
Despite the challenges 2020 presented, there continued to be excellent research which was published throughout the year. In this post we have collated our top five most read AHRI insights and our top five most listened to podcasts for 2020.
This AHRI insight is not for the faint-hearted. This recent AHRI research by Chinese postdoc Hongju Ma and others documents the first case of metabolic resistance to metribuzin in ryegrass in Australia. The ryegrass in this population was only about 3 fold resistant to Atrazine and Metribuzin. The researchers used a P450 inhibitor, PBO, and radiolabelled metribuzin to help determine that the resistance is metabolism-based, likely due to P450 enzyme activity.
Welcome to the highlight reel of AHRI’s recently released blockbuster – ‘Don’t stick to it!’. Set in the labs, glasshouses and fields of this world-leading research powerhouse, and featuring renown giants of the herbicide resistance world – Powles, Busi, Yu and Owen, this latest exposé will have you seriously impressed! ‘Don’t stick to it!’ delves into five years of ground-breaking scientific discovery and its value to Australian farmers in their epic battle against profit-sucking weeds.
This AHRI insight is not for the faint-hearted. It is the work of AHRI researcher, Dr Danica Goggin who has dedicated many years to working out how auxin herbicides such as 2,4-D and Dicamba work, and how plants evolve resistance to them. Danica’s research found that plants with fewer receptors on their cell membranes were resistant to 2,4-D due to reduced perception of the 2,4-D. Putting this molecular biology research into words is challenging, so we have created some videos that explain it.
It’s a quaint tradition that many brides follow – ‘Something old; represents continuity with the past and ‘Something new’ offers optimism for the future. ‘Something borrowed’ passes on another’s secrets for success and ‘Something blue’ represent key features of a solid relationship. Finally, ‘A sixpence in your shoe’ for prosperity. With the release of several new modes of action and chemical formulations, it’s helpful to first consider how these ‘new’ chemicals might revive some ‘old’ chemistry.
How long have you lived where you live? If you’re a long-time local you will have seen new people come and go – some are gone before you get to know them and others stay and find their niche in the community. Weed communities also change over time and it can take some effort to get to know and understand the new-comers. Will they thrive? Do they fit in? Will they disrupt the way things are done? Or will they go away again, almost unnoticed?
