AHRI Snapshots is a podcast which provides information on what we do at the Australian Herbicide Resistance Initiative, as well as finding out what other researchers in weed science are up to around the country and the world. AHRI's researchers work out of the University of Western Australia, right next to the beautiful Swan River in WA's capital, Perth.

    AHRI Director Hugh Beckie reflects on 2021

    This is the last AHRI Snapshots for 2021! What a year it has been. In this episode we’re catching up with AHRI Director, Hugh Beckie to go over the highlights from AHRI this year.

    We’ll also get an update on what the plans are for AHRI in 2022.

    This is now our 6th season of the podcast. Thank you for listening  this year and we look forward to bringing you more AHRI Snapshots in 2022!

    AHRI's getting a new website!

    AHRI's getting a new website!

    We've got exciting news! AHRI is getting a new website next week!

    AHRI Communications Officer, Jessica Scholle joins me on the podcast today to chat about this new development and we also give a broader communications update on AHRI.

    You might've noticed we've been getting to know our AHRI researchers better through videos. We talk about the strategy behind this.

    We also keep you in the loop with developments on our online courses through Diversity Era.

    To ensure you're seeing the latest from AHRI, make sure you're following us on Twitter here.

    You can do our latest updated course, HWSC 101 here.

    And sign-up to our monthly blog, AHRI insight, here.

    New soil moisture mapping technique proves to be more efficient and accurate

    New soil moisture mapping technique proves to be more efficient and accurate

    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.

    What's happening at the Crop Protection Forum next week?

    What's happening at the Crop Protection Forum next week?

    The Crop Protection Forum is next week in Launceston, Tasmania!

    In its 7th year, the AHRI, CCDM and Cesar Australia Crop Protection Forum will showcase the latest weeds, pests and disease research for riding out the inevitable storm of chemical resistance.
    Our experts will explore the implications and solutions for reducing resistance in Tasmanian cropping systems.

    In this podcast episode, Mark Gibberd from CCDM, Hugh Beckie from AHRI and Joshua Thia from University of Melbourne, representing Cesar Australia, provide a snapshot of what to expect at the forum.

    Tickets are still available and you can get all the information for the event here.

    How phase farming can reduce an annual ryegrass seedbank

    How phase farming can reduce an annual ryegrass seedbank

    In this podcast, we catch up with AHRI Agronomy Researcher Dr Yaseen Khalil about some of the key findings from two of his recent studies. 

    We learn about the effectiveness of different weed control tacts in serradella, which is a legume pasture species. 

    We  also  learn about how pasture phase farming can be used to reduce the annual ryegrass seed bank in a serradella crop.

    Yaseen’s project is funded by the Grains Research and Development Corporation, which invests $1.5 million in AHRI each year to ensure Australian grain growers have access to world class research in strategies to mitigate weeds and control herbicide resistance.

    Rapid on-farm testing of ryegrass to pre and post-em herbicides explained

    Rapid on-farm testing of ryegrass to pre and post-em herbicides explained

    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 paper

    Overreliance 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 pot-based dose-response assays, effect of seed dormancy, and stability of herbicides in agar. Easy-to-interpret results were obtained using non-dormant seeds from susceptible and resistant populations, and resistance was detected similarly as pot-based assays. However, the test is not suitable for trifluralin because of instability in agar as measured over a 10-d period, as well as freshly-harvested seeds due to primary dormancy.
    This study demonstrates the utility of a portable and rapid assay that allows for on-farm testing of clethodim, glyphosate, and pyroxasulfone resistance in L. rigidum, thereby aiding the identification and implementation of effective herbicide control options.
    Read the paper here.
