AHRI 2020 Wrap Up

 

Season’s greetings from the AHRI Team

 

Written by: Jessica Strauss

While 2020 presented challenges for us all, including in the research space, we were fortunate to be able to continue to operate at AHRI, with most research projects unaffected. We know from our colleagues over east and internationally, that was not always the case, with research trials being interrupted and lab work at times postponed.

Despite the challenges 2020 presented, there continued to be excellent research which was published throughout the year. Below, we have collated our top five most read AHRI insights and our top five most listened to podcasts for 2020. We already have lots of exciting new research in the bank which we’ll be publishing AHRI insights on in 2021, so this post will let you easily catch up on the 2020 highlights, so you’re ready for a year of exciting research outcomes in 2021!

Before you get stuck  into the content below, the AHRI Team would like to extend a big thank you to our subscribers for their continued support and engagement with AHRI. We wish you a lovely festive season and look forward to sharing more research with you next year.

So you don’t miss out on AHRI content, you can follow us on Twitter here and subscribe to AHRI insight here.

AHRI insight

Our most read AHRI insight this year was on AHRI researcher Jingbo Li’s paper “2,4-D antagonizes glyphosate-resistant barnyard grass Echinochloa colona“.

Peter Newman summarised the research:

“When we are applying herbicides to susceptible weeds, the reality is that we are often high on the dose response curve and we don’t notice low level antagonism from mixing partners. When applying herbicides to weeds with low to medium level resistance we are often applying just enough herbicide to kill the weed, and any antagonism of this rate of herbicide will lead to reduced weed kill. We have known for some time that mixing 2,4-D products with glyphosate can cause minor antagonism for grass weed control and this research demonstrates that this is now of particular importance when we are dealing with glyphosate resistant weeds.”

You can read the AHRI insight in full below.

Number 1

2,4-D antagonises glyphosate, especially in glyphosate resistant weeds

Number 2

Luximax gets its own NEW box

Number 3

Something old, something new in annual ryegrass control

Number 4

Hoe, hoe, hoe and away weeds go!

Number 5

I can’t live without the Internet!! And I can’t farm without glyphosate.

AHRI Snapshots Podcast 

We had another great year for the AHRI Snapshots podcast. We were joined by guests across Australia and internationally who shared their latest research outcomes with us. We touched base with Associate Professor Todd Gaines in the US, as well as Professor Martin Vila-Aiub in Argentina who were both candid about their research updates and the challenges they faced in their respective countries during this difficult year. The AHRI Team jumped on the mic throughout the year too, providing valuable insights into their research. Dr Danica Goggin and Dr Roberto Busi’s episodes both made the top five below, so if you missed them, make sure to give them a listen!

Thank you to all the guests who came on the podcast in 2020 – it can be a bit scary at first, but everyone was fantastic and presented their research in a different way to give us a more comprehensive understanding of their papers. We look forward to bringing you more AHRI Snapshots podcasts in 2021! For now, please enjoy take a listen to our top five podcasts below.

Number 1

Why delaying sowing isn’t necessarily the best option for ryegrass control

Number 2

The complexities of 2,4-D resistance explained by AHRI researcher Dr Danica Goggin

Number 3

Number 4

On a good thing? Don’t stick to it! – the Director’s Cut – an overview of AHRI 5 and what’s to come

Number 5

Northern region growers in unique position to incorporate other weed control methods
