Hot spot on goosegrass genome is a herbicide resistance generator

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 ...

Hybrid versus open-pollinated canola

Over the last few years, the AHRI agronomy team has done extensive work looking at crop competition in hybrid and open-pollinated canola. Project lead, Dr Mike Ashworth, joins us on this podcast to discuss the findings on ideal seeding rate, variety, row spacing and seed size. Herbicides are currently working quite well in canola. We know that herbicide resistance is a real threat though, so we discuss what the current trends are in herbicide use in canola crops and what growers need to do ...

Deep learning can tell the difference between white and blue lupins

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 For...

Testing water quality for effective spray application

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...

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

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 collaborati...

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

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 gu...

The benefits of 3D mapping soil moisture

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 ag...

Professor Steve Duke talks on upcoming Herbicide Discovery and Development conference

This month on the podcast, we’re going to be finding out about the upcoming Herbicide Discovery and Development Conference, which is happening from January 18 to 20, 2023 at Curtin University. Due to genetic resistance to many of the most used herbicides, the need for new ones is greater than ever. This conference invites you to be part of the solution! University of Mississippi Adjunct Research Professor, Steve Duke, will be the keynote speaker on Thursday January 19. He’ll be talking o...

Why highly glyphosate resistant plants can’t compete

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 th...

Velocity® resistant wild radish confirmed

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 ext...

Reduced cinmethylin sensitivity identified in annual ryegrass in lab

In this episode of AHRI Snapshots, we’re catching up with AHRI’s Dr Danica Goggin about her latest paper which looks at cinmethylin metabolism in annual ryegrass. Cinmethylin is a relatively new pre-emergent herbicide to Australian cereal cropping farming systems. While there hasn’t been any confirmed resistance of annual ryegrass to cinmethylin, there has been some populations which have had reduced sensitivity to it. Danica joins us to explain what the paper authors found the ca...
