Is thermal weed control a site-specific reality?

Our extension officer Kirrily Condon recently wrote an AHRI insight entitled “Thermal weed control – just hot air, or site-specific reality?” It looked at work by a team from the University of Sydney. Guy Coleman and his colleagues reviewed 170 papers, which demonstrated that mechanical weed control options, like tillage, can use significantly less energy than thermal options, like heat, to kill weeds. Herbicide energy use sits somewhere in the middle. We chat with Guy to find out a bit more.

Recent development and trends in herbicide resistance management

agronomy

Today on AHRI Snapshots, we’re chatting with AHRI Director about the recent AHRI review paper “Herbicide Resistance Management: Recent Developments and Trends”. This paper covers recent developments and trends in herbicide-resistant weed management in agronomic field crops. This paper was written by AHRI’s Director Hugh Beckie, Dr Mike Ashworth and Dr Ken Flower and has helped shape the AHRI agronomy program going forward.

Pulse crop agronomy and the implications for weed competition

On this week’s podcast, we’re chatting with Darling Downs-based consultant from PulseAg Consulting, Kerry McKenzie (pictured top left). He has done work on pulse crop agronomy and the implications for weed competition and he’s going to give us an overview of the results out of the Darling Downs and Emerald trials. Kerry’s previous agronomy work has helped inform researchers from the University of Queensland Gulshan Mahajan and ‘Sunny’ Chauhan with ways to give chickpea crops a competitive advantage against annual ryegrass.

Importance of resistance testing galvanised in GRDC-funded ‘Focus Farms’ Project

In this edition of AHRI Snapshots, we’re chatting with AHRI’s Dr Roberto Busi about his GRDC-funded Focus Farms Project which recently wrapped up in March this year. The project was based in the Kwinana Port Zone in Western Australia. Its primary aim was to demonstrate the value of growers testing for herbicide resistance. Roberto gives a great overview of, how the project came about; what he discovered; and how growers can utilise this information.

It turns out trifluralin resistance is different

Dr Jinyi Chen

AHRI PhD student, Jinyi Chen, studied the inheritance of trifluralin resistance with target site resistance in ryegrass. She found that resistance is single gene recessively inherited. This means that both parents must have a copy of the resistance gene for the progeny to be resistant. Recessive resistance inheritance is rare in the world of herbicide resistant weeds. Nearly all other cases of target site herbicide resistance involve semi-dominance. Take a listen to learn more!

Pre-lim results on canola crop competitiveness

AHRI’s Agronomy Lead, Mike Ashworth, provides an update on the trial work the agronomy team has been doing. We find out a bit more details about some of the preliminary results from trials conducted in 2018 and we also get a snapshot of what they’re looking at this year.
