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 StraussY

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/

On this AHRI Snapshots we learn all about the weed chipper!We chat with agricultural engineer Dr Andrew Guzzomi from the University of Western Australia’s School of Engineering about the weed chipper. Andrew, together with his colleague Dr Carlo Peressini, engineered the weed chipper’s development as part of a multidisciplinary team.The concept of the Weed Chipper came about when a group of growers were discussing weed control in a fallow field in southern Queensland – this prompted the idea of a rapid response tyne to chip out weeds. The group of agricultural engineers and weeds researchers led by Dr Michael Walsh (who also is interviewed on this podcast), Associate Professor and Director of Weed Research with the University of Sydney, along with grower and industry advisors, built and tested prototypes of the Weed Chipper, and paved the way to its commercialisation.The project received funding from the Grains Research and Development Corporation and was created in response to the growing concerns about herb

On this week’s AHRI Snapshots we chat with Dr Gurjeet Gill. He’s an Associate Professor in Agronomy & Weed Science at the School of Agriculture, Food and Wine at University of Adelaide.Gurjeet, along with his colleague Ben Fleet recently completed some research that says if you don’t get a knockdown in, it’s not a problem. Delaying the sowing of wheat or barley to get a knockdown in some cases lead to a reduced number of grass weeds in crop, but the weeds in the later sown crop often set more seeds than the lower number of weeds in the early sown crop.This work was also covered in AHRI insight last week by Peter Newman - check it out here: https://ahri.uwa.edu.au/dont-delay-sowing-to-beat-ryegrass/You can follow AHRI on Twitter here.
