The impact of drought on weeds research

QDAF Principal Research Scientist, Michael Widderick recently visited AHRI in Perth. Michael’s team are working on crop competition (among other projects), focusing on sorghum, pulse crops, and manipulation of crop competitiveness to suppress typically summer emerging weeds in winter crops. There are some similarities with the crop competition work our agronomy team are doing. Michael explains some of the barriers to crop competition adoption in the Northern region.  We also discuss how the drought in the Northern region impacts research outcomes.

Certain chemicals in wheat roots found to act as effective bio-herbicides in Aussie soils

Our latest AHRI insight being published soon, ‘Crops are doin’ it for themselves’, written by Cindy Benjamin, looks at work around crop competition out of Charles Sturt University. The main project is led by Professor Leslie Weston at CSU and Associate Professor Dr Chris Preston at The University of Adelaide, to investigate several aspects of crop competition. The AHRI Insight delves into just one set of experiments within the broader project, that investigated the ‘impact of crop cultivar on in-crop and post-harvest weed suppression’. In this podcast, Leslie gives an overview of this important work.

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.
