On this episode of AHRI Snapshots, we caught up with AHRI Masters Graduate Ci Sun. She published her first paper as first author recently on the adaptive value of flowering timing in wild radish. The paper has some important key takeaway messages which we get into in this interview.You can read Ci's paper here: https://ahri.uwa.edu.au/publications/the-adaptive-value-of-flowering-time-in-wild-radish-raphanus-raphanistrum/We also mentioned the WeedSmart Big 6 to look at diverse tactics for weed control. You can check out the Big 6 here: https://www.weedsmart.org.au/big-6/Presenter & producer: AHRI Communications Lead Jessica Strauss

We’re well into 2021 and the team at AHRI has been really busy with research and extension. AHRI Director Hugh Beckie joins us on the podcast to provide us with an update on research outcomes out of AHRI, as well as an overview of his new paper on an agricultural weed assessment calculator which can be used in Australia. NEW RESEARCH OUT OF AHRIWorld first: glyphosate resistant capeweed: https://ahri.uwa.edu.au/world-first-glyphosate-resistant-capeweed/Agricultural Weed Assessment Calculator: An Australian Evaluation: https://ahri.uwa.edu.au/publications/agricultural-weed-assessment-calculator-an-australian-evaluation/Cytochrome P450 CYP81A10v7 in Lolium rigidum confers metabolic resistance to herbicides across at least five modes of action: https://ahri.uwa.edu.au/publications/cytochrome-p450-cyp81a10v7-in-lolium-rigidum-confers-metabolic-resistance-to-herbicides-across-at-least-five-modes-of-action/

In this edition of AHRI Snapshots, we’re chatting with AHRI Agronomy Team researcher, Dr Yaseen Khalil about his latest paper which identified the world’s first glyphosate resistant capeweed.

A group of researchers led by Heping Han from AHRI, including researchers from Bayer and Zhejiang University in China have identified the P450 gene responsible for cross resistance to herbicides of at least five modes of action. The gene is CYP81A10v7. Paper author, Prof Steve Powles joins us in this AHRI Snapshots to provide a history of this research and what the finding means in both a fundamental and practical sense. AHRI recently published a paper on this and last week Peter Newman wrote an AHRI insight on it.

This is our last AHRI Snapshots podcast for 2020! On our final episode, AHRI PhD Candidate Nooshin Shahbazi joins us to talk about her latest paper "Comparison of crop and weed height, for potential differentiation of weed patches at harvest". She has been looking at differentiating between weeds and the crop at harvest time based on the plants height differences, with the aim of identifying weed species that persist in the field until harvest and grow taller than the crop plants, so that these weed species could be mapped at the next stage of the project and treated.With the increasing challenges associated with herbicide-based weed control due to chemical residue and herbicide resistance, innovative approaches to weed control are becoming more sought after.If you'd like to check out Nooshin's paper, you can read it here: https://ahri.uwa.edu.au/publications/comparison-of-crop-and-weed-height-for-potential-differentiation-of-weed-patches-at-harvest/Producer and Presenter: Jessica Strauss

Today on AHRI Snapshots we catch up with AHRI’s Dr Roberto Busi. He recently published a paper alongside AHRI's Prof Hugh Beckie which entitled: Are herbicide mixtures unaffected by resistance? A case study with Lolium rigidum. He joins us to tell us what he found.Paper:https://ahri.uwa.edu.au/publications/are-herbicide-mixtures-unaffected-by-resistance-a-case-study-with-lolium-rigidum/

In this edition of AHRI Snapshots, we catch up with Colorado State University weeds researcher, Associate Professor Todd Gaines. Todd has previously worked out of AHRI and we thought it would be good to catch up with him to see what he’s focusing on at the moment. Todd recently had a paper feature in the Special Edition of Herbicide Resistance in Plants, edited by AHRI's Prof Hugh Beckie, entitled “Omics Potential in Herbicide-Resistant Weed Management”. We find out about that and Todd also shares an exciting finding on 2,4-D resistance which will be published in an upcoming paper.

This year, AHRI is hosting the 2020 Crop Protection Forum on Tuesday December 8th. This event is a collaboration between AHRI, CCDM and cesar and is designed to deliver the latest research to agronomists and industry in a one-day event. This event was first held in Perth in 2015 when it was hosted by AHRI. The event has since been delivered in Wagga, Dalby, Adelaide, and Moama in Victoria and has proved to be a valuable forum for agronomists to engage with crop protection researchers and discuss the regional issues arising and how to tackle these problems.Today on AHRI Snapshots, WeedSmart Southern Extension Agronomist Greg Condon who presented at Moama's event gives an overview of what to expect, and one of last year's attendees, Birchip Cropping Group's Kelly Angel gives her perspective.

In this week's podcast, we catch up with AHRI Research Officer, Roberto Lujan Rocha who gives an update on where the agronomy team is at with a range of their projects. We talk about how the team is looking at whether certain weeds like ryegrass and wild radish evolve to evade harvest weed seed control tactics and also cover work the team is doing in pre-emergent herbicides. In the podcast, Roberto mentions a range of resources that discuss the work of the agronomy team. ‘Intelligent’ weeds evolve to evade controls: https://grdc.com.au/news-and-media/news-and-media-releases/national/2020/may/intelligent-weeds-evolve-to-evade-controlsFighting weeds with plants in the west: https://groundcover.grdc.com.au/weeds-pests-diseases/weeds/plant-establishment-critical-to-out-compete-weedsThe interaction between wheat (Triticum aestivum), time-of-seeding and choice of pre-emergent herbicide on annual ryegrass (Lolium rigidum) growth and competition: https://grdc.com.au/resources-and-publications/grdc-update-papers/tab-content/grdc-update-papers/2020/02/the-interaction-between-wheat-triticum-aestivum,-time-of-seeding-and-choice-of-pre-emergent-herbicide-on-annual-ryegrass-lolium-rigidum-growth-and-competition.This research Roberto talks about in this podcast will be presented by AHRI Weed Agronomy Lead Mike Ashworth at the Crop Protection Forum in Perth in December (get your tickets here: https://ahri.uwa.edu.au/crop-protection-forum-2020/) and also at GRDC Updates in 2021.

In this episode of AHRI Snapshots, we catch up with Professor Martin Vila-Aiub to find out about his recent paper "Fitness of Herbicide-Resistant Weeds: Current Knowledge and Implications for Management" which was recently published in a special edition of Herbicide Resistance in Plants (you can read that here: https://ahri.uwa.edu.au/publications/herbicide-resistance-in-plants-2/).Martin also tells us about how he's been utilising his time in Argentina during the pandemic (he's been doing lots of writing!).
