When a young Eva Kollisch arrives as a refugee in New York in 1940, she finds a community among socialists who share her values and idealism. She soon discovers ‘the cause’ isn’t as idyllic as it seems. Little does she know this is the beginning of a lifelong commitment to activism and her determination to create radical change in ways that include belonging, love and one's full self. In addition to Eva Kollisch’s memoirs Girl in Movement (2000) and The Ground Under My Feet (2014), LBI’s collections include an oral history interview with Eva conducted in 2014 and the papers of Eva’s mother, poet Margarete Kolllisch, which document Eva’s childhood experience on the Kindertransport. Learn more at www.lbi.org/kollisch . Exile is a production of the Leo Baeck Institute , New York | Berlin and Antica Productions . It’s narrated by Mandy Patinkin. Executive Producers include Katrina Onstad, Stuart Coxe, and Bernie Blum. Senior Producer is Debbie Pacheco. Associate Producers are Hailey Choi and Emily Morantz. Research and translation by Isabella Kempf. Sound design and audio mix by Philip Wilson, with help from Cameron McIver. Theme music by Oliver Wickham. Voice acting by Natalia Bushnik.

In this episode, we’re catching up with AHRI’s Dr Heping Han to talk about some recent research he published on 2,4-D syngergising metribuzin. Australian farmers and agronomists have previously observed synergy between phenoxy herbicides, such as 2,4-D and PSII herbicides, also known as Group C or Group 3 herbicides such, as metribuzin. Thanks to this new AHRI research, we now know why this is the case. Dr Heping Han joins us to explain this research and what it means for farming systems.The Grains Research and Development Corporation (GRDC) 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.

Hot spot on goosegrass genome is a herbicide resistance generator 7:52

cách đây 1 year trước7:52

7:52

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 was translocated to the sub-telomer region and duplicated many times there, leading to glyphosate resistance occurring. This work is useful not only in resistance gene discovery, but also in the development of gene-based next generation herbicides, like RNAi, as well as genetic reversal of resistance. It will also contribute to studying the weediness and adaptation of this global weed species.

In this episode, we catch up with visiting Associate Professor Todd Gaines. Todd is from Colorado State University and is currently working from UWA with AHRI. In September, he’ll be at the International Plant and Animal Genome Australia conference in Perth city, where he’s organising a two-hour session of invited talks. Todd is also organising a subsequent workshop at UWA on September 22nd, which will have the theme “We have weed genomes, but what do we do now?” While herbicides are the most effective and widely adopted weed management practice, the evolution of multiple herbicide resistance in damaging weed species threatens the yield and profitability of many crops. Todd is an expert in how genomics and molecular biology can contribute to improving weed management. He’ll explain what the focus will be at these upcoming events in this chat.

Deep learning can tell the difference between white and blue lupins 15:25

cách đây 2 years trước15:25

15:25

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 Forrest Research Scholar, Monica Danilevicz comes in. The team has recently taken the approach of using weed labelling and deep learning algorithms to see if they can distinguish between the two lupin species in images captured by unmanned aerial vehicles, known as UAVs, like drones, or ground-based cameras. The aim is to detect and spray just the blue lupins in crop. Monica explains the results further in this chat.

Testing water quality for effective spray application 14:18

cách đây 2 years trước14:18

14:18

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 September 2022 and has recently completed surveys of water sources in the Merredin area of Western Australia. So why is this survey work important? Well, when it comes to optimising spray efficacy, water quality is an integral component. Roberto’s initial survey showed that some water sources might fall outside the ideal ranges to ensure good spray application. He explains the survey results in detail in this chat.

How scientists are studying summer weeds to predict and mitigate future resistance 18:09

cách đây 2 years trước18:09

18:09

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 collaboration with AHRI and University of Adelaide. You can follow AHRI on Twitter here .

Cinmethylin couldn't be broken, but diversity is key to keeping it that way 9:32

cách đây 2 years trước9:32

9:32

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 guarantee that resistance won’t develop, and the best way to prevent that is by using diverse weed control tactics.

The benefits of 3D mapping soil moisture 14:49

cách đây 2 years trước14:49

14:49

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 agriculturally marginal lands. This is a deviation a bit away from the themes of weed control we usually cover in this podcast, however, looking at farming systems holistically is important. Land not suitable for crops can be a haven for weeds to proliferate, which in turn can end up in the crop. Planting a valuable species like Leptospermum nitens can provide an additional income source, and reduce the land availability for weeds to grow. Hira chats to us about her findings, as well as the other applications 3D mapping can provide growers. You can follow AHRI on Twitter here .

Why highly glyphosate resistant plants can’t compete 12:41

cách đây 2 years trước12:41

12:41

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 the TIPS mutation by 95%, and the addition of glyphosate actually made these plants grow a little better!

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 extensive glasshouse and field testing. Resistance testing and using diverse tactics, as found in the WeedSmart Big 6 , continues to be key in preserving chemistries into the long-term.
