Ahri Snapshots

For the first time in Western Australia, annual ryegrass from a cropped paddock was found to be resistant to glyphosate and paraquat (among other modes of action).AHRI Senior Research Fellow Dr Roberto Busi joins us on the podcast today to give an overview of this finding as a pre-cursor to an upcoming WeedSmart webinar.In this webinar,  he will present the preliminary results he obtained in recent glasshouse trials, which aimed to characterise the resistance.Farmanco Agronomist Consultant Brent Pritchard will provide some context on how this resistance evolved in the field.Roberto will conduct two field trials in 2022. He will explain what treatments he’s planning to test, and attendees will have the opportunity to provide feedback on those treatment options.You can register for this webinar which is occurring on March 30 by clicking on this link.You can follow AHRI on Twitter here.

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. You can follow AHRI on Twitter here.

In this interview, we’re catching up with PhD candidate, Hira Shaukat. Hira’s first paper has just been published in the Agriculture Water Management Journal. It’s entitled “Quasi-3D mapping of soil moisture in agricultural fields using electrical conductivity sensing”.  The soil moisture measurement technique described in this paper has proven to be more efficient and accurate than other previous methods used. Hira joins us today to provide an insight into her PhD project and how this new soil moisture measurement technique described in her first paper will help farmers gather more accurate and helpful data and make more informed decisions about their farming inputs like seeding rates and fertiliser inputs. One of Hira's supervisors is Dr Ken Flower, who sits within the AHRI team and works closely with our researchers. We're excited to report on the first paper from Hira Shaukat and congratulate her on some very interesting and practical results. LinksPaper: Quasi-3D mapping of soil moisture in agr

On today’s AHRI Snapshots, we’re catching up with previous AHRI Masters student Martina Badano.Martina worked with Dr Roberto Busi back in 2019 on rapid on-farm testing.Her paper “Rapid On-Farm Testing of Resistance in Lolium rigidum to Key Pre- and Post-Emergence Herbicides” has just been published. We’re going to find out more about it.Here's some more detail on the paperOverreliance on herbicides for weed control is conducive to the evolution of herbicide resistance.Lolium rigidum (annual ryegrass) is a species that is prone to evolve resistance to a wide range of herbicide modes of action. Rapid detection of herbicide-resistant weed populations in the field can aid farmers to optimize the use of effective herbicides for their control.The feasibility and utility of a rapid 7-d agar-based assay to reliably detect L. rigidum resistant to key pre- and post-emergence herbicides including clethodim, glyphosate, pyroxasulfone and trifluralin were investigated in three phases: correlation with traditional po

AHRI researcher, Dr Danica Goggin and others have recently discovered how ryegrass has evolved resistance to Sakura.  It’s all about GSTs. Not the tax type, rather gluthione transferase (Danica explains in the podcast why the 'S' was dropped!). Wheat uses GSTs to detoxify and tolerate Sakura, and ryegrass has now evolved to do the same thing, although the ryegrass is not as tolerant as the wheat. The researchers found that it is up regulation of GSTs in the roots of the plant that causes the resistance.Dr Danica Goggin joins us on the podcast to explain these findings. You can read her paper in full here. You can follow AHRI on Twitter here. To learn more about AHRI's research and team, check out the website here.

In this episode we catch up with AHRI Director Hugh Beckie who recently presented at WeedSmart Week in Esperance.
