In this episode, we delve into the concept of being "qualified" in the workplace, examining who gets labeled as such, who doesn't, and the underlying reasons. We explore "competency checking"—the practice of scrutinizing individuals' abilities—and how it disproportionately affects underrepresented groups, often going unnoticed or unchallenged. Our discussion aims to redefine qualifications in a fair, equitable, and actionable manner. Our guest, Shari Dunn , is an accomplished journalist, former attorney, news anchor, CEO, university professor, and sought-after speaker. She has been recognized as Executive of the Year and a Woman of Influence, with her work appearing in Fortune Magazine, The Wall Street Journal, Ad Age, and more. Her new book, Qualified: How Competency Checking and Race Collide at Work , unpacks what it truly means to be deserving and capable—and why systemic barriers, not personal deficits, are often the real problem. Her insights challenge the narratives that hold so many of us back and offer practical solutions for building a more equitable future. Together, we can build workplaces and communities that don’t just reflect the world we live in, but the one we want to create. A world where being qualified is about recognizing the talent and potential that’s been overlooked for far too long. It’s not just about getting a seat at the table—it’s about building an entirely new table, one designed with space for all of us.

Glufosinate is an important and widely used non-selective herbicide active on a wide range of plant species.

Resistance evolution to glufosinate in weedy plant species, including the global weed Eleusine indica, commonly known as goosegrass, is underway.

At AHRI, Principal Research Fellow, Qin Yu and her team established the molecular basis of target-site glufosinate resistance in goosegrass.

In this first AHRI Snapshots podcast for 2022, Qin Yu joins us to explain the results in the paper: A naturally evolved mutation (Ser-59-Gly) in glutamine synthetase confers glufosinate resistance in plants.

This work reveals a naturally evolving point mutation in glutamine synthetase that confers resistance to glufosinate in Eleusine indica, known as goosegrass.

Hot spot on goosegrass genome is a herbicide resistance generator 7:52

منذ 1 year7:52

7:52

In this AHRI Snapshots, we catch up with Principal Research fellow, Dr Qin Yu about her latest paper on glyphosate resistance in goosegrass. This paper was published in Nature Communications in August 2023, which is an impressive achievement. This paper is complicated, but essentially the researchers have found a hot spot on the genome of goosegrass that is a herbicide resistance generator. In this research, the team found that in glyphosate-resistant goosegrass the EPSPS gene was translocated to the sub-telomer region and duplicated many times there, leading to glyphosate resistance occurring. This work is useful not only in resistance gene discovery, but also in the development of gene-based next generation herbicides, like RNAi, as well as genetic reversal of resistance. It will also contribute to studying the weediness and adaptation of this global weed species.

What do we do with weed genomes? 21:06

منذ 2 years21:06

21:06

In this episode, we catch up with visiting Associate Professor Todd Gaines. Todd is from Colorado State University and is currently working from UWA with AHRI. In September, he’ll be at the International Plant and Animal Genome Australia conference in Perth city, where he’s organising a two-hour session of invited talks. Todd is also organising a subsequent workshop at UWA on September 22nd, which will have the theme “We have weed genomes, but what do we do now?” While herbicides are the most effective and widely adopted weed management practice, the evolution of multiple herbicide resistance in damaging weed species threatens the yield and profitability of many crops. Todd is an expert in how genomics and molecular biology can contribute to improving weed management. He’ll explain what the focus will be at these upcoming events in this chat.

Deep learning can tell the difference between white and blue lupins 15:25

منذ 2 years15:25

15:25

Blue lupins are notorious for being difficult to control and plants produce prolific seed banks. Blue lupins are closely related to the domesticated narrow-leaf lupin, also known as the white lupin, so whichever herbicide is survived by white lupins is also survived by blue lupins. This is problematic as they look alike. This is where a team of researchers from AHRI and the Centre for Applied Bioinformatics at the University of Western Australia, led by UWA PhD candidate and Forrest Research Scholar, Monica Danilevicz comes in. The team has recently taken the approach of using weed labelling and deep learning algorithms to see if they can distinguish between the two lupin species in images captured by unmanned aerial vehicles, known as UAVs, like drones, or ground-based cameras. The aim is to detect and spray just the blue lupins in crop. Monica explains the results further in this chat.

Testing water quality for effective spray application 14:18

منذ 2 years14:18

14:18

In this interview we chat with AHRI Research Officer Roberto Lujan Rocha about the survey work he has conducted on the quality of water sourced on farm for spray application. This project is a collaboration between University of Western Australia, AHRI and the Centre for Water & Spatial Science. The team looked at water from bores, dams, desalinated water, rainwater tanks and scheme water. Roberto surveyed water sources in the mid to south West Australian wheatbelt in September 2022 and has recently completed surveys of water sources in the Merredin area of Western Australia. So why is this survey work important? Well, when it comes to optimising spray efficacy, water quality is an integral component. Roberto’s initial survey showed that some water sources might fall outside the ideal ranges to ensure good spray application. He explains the survey results in detail in this chat.

How scientists are studying summer weeds to predict and mitigate future resistance 18:09

منذ 2 years18:09

18:09

As reliance on pre-emergent herbicides for both broadleaf and grass species is increasing, it’s essential to understand the dynamics of weed-herbicide interactions in the field. Dr Mahima Krishnan and her colleagues from University of Adelaide are in the process of studying populations of summer weeds to help predict and then mitigate any future resistance that maybe develop by implementing appropriate herbicide application strategies. This is a project funded by GRDC and in collaboration with AHRI and University of Adelaide. You can follow AHRI on Twitter here .

Cinmethylin couldn't be broken, but diversity is key to keeping it that way 9:32

منذ 2 years9:32

9:32

On this episode of AHRI Snapshots, we’re catching up with former AHRI master’s student Geide Figueiredo (also known as JD) who worked alongside AHRI researcher Roberto Busi to try and break the herbicide cinmethylin, commercially known as Luximax. Fortunately, they weren't able to break it, which is great news for farmers and agronomists because it means that this herbicide is still working and resistance hasn’t developed. However, it’s always important to remember there’s no guarantee that resistance won’t develop, and the best way to prevent that is by using diverse weed control tactics.

The benefits of 3D mapping soil moisture 14:49

منذ 2 years14:49

14:49

In our first episode back for AHRI Snapshots this year, we chat with Dr Hira Shaukat, who previously was an AHRI PhD candidate. Hira worked on 3D mapping of soil moisture throughout her PhD. Part of her work involved looking at how farmers could utilise degraded land affected by salinity. This involved figuring out what soil conditions would be suit the plant Leptospermum nitens. Nectar from this plant is a source of high-value medicinal honey production and can provide income from agriculturally marginal lands. This is a deviation a bit away from the themes of weed control we usually cover in this podcast, however, looking at farming systems holistically is important. Land not suitable for crops can be a haven for weeds to proliferate, which in turn can end up in the crop. Planting a valuable species like Leptospermum nitens can provide an additional income source, and reduce the land availability for weeds to grow. Hira chats to us about her findings, as well as the other applications 3D mapping can provide growers. You can follow AHRI on Twitter here .

In this AHRI Snapshots we catch up with Dr Martin Vila-Aiub, who was co-author on a recent publication that our latest AHRI insight covers . It’s all about how highly glyphosate resistant plants can’t compete. AHRI researchers recently teamed up with Martin, who is based in Argentina and other researchers from Brazil to investigate the combination of crop competition and glyphosate on glyphosate-resistant goosegrass. Competition alone from Soybeans reduced the growth of plants with the TIPS mutation by 95%, and the addition of glyphosate actually made these plants grow a little better!

AHRI’s Dr Roberto Busi talks about his finding of velocity resistant wild radish in this podcast. It’s not great news for growers – but knowledge is power. At the end of 2019, Roberto Busi started a new herbicide resistance testing service based at UWA . Growers and agronomists sent in about 500 samples of ryegrass for testing as well as 121 samples of wild radish. Two of these wild radish populations, sampled by agronomists, had survivors to Velocity® and Roberto embarked on extensive glasshouse and field testing. Resistance testing and using diverse tactics, as found in the WeedSmart Big 6 , continues to be key in preserving chemistries into the long-term.
