AHRI Snapshots is a podcast which provides info on what we do at AHRI, as well as updates on weeds research from across the country and internationally.

AHRI researchers work out of the University of Western Australia, next to the beautiful Swan River in WA’s capital, Perth.

Do plants pay a fitness cost to be resistant to glyphosate?

Today we catch up with AHRI’s Dr Qin Yu about the paper “Do plants pay a fitness cost to be resistant to glyphosate?” This paper was published earlier this year and is written by Martin Vila-Aiub, Qin Yu and Steve Powles. This paper reviewed the literature to understand the effects of glyphosate resistance on plant fitness as the molecular, biochemical and physiological levels.

What are canola’s super-powers?

In this podcast, Cindy Benjamin catches up with Charles Sturt University (CSU) Professor Leslie Weston to get the next instalment on their work. The last podcast with Leslie focused on cereals, while this one looks at the mechanisms at play in canola. Leslie led a large project at CSU alongside Associate Professor Dr Chris Preston at The University of Adelaide, to investigate several aspects of crop competition. PhD candidate James Mwendwa and the project team conducted field trials at Wagga Wagga comparing the weed-suppressive effect of six hybrid and one open-pollinated canola cultivars, both in-crop and post-harvest, in 2014.

Harvest Weed Seed Control model explained

For this AHRI Snapshots podcast, we catch up with AHRI and WeedSmart Western Extensions Agronomist, Peter Newman, who wrote one of our latest AHRI insights on the best harvest weed seed control tool for you. He also developed a model which allows you to input your own data to figure out what options you might consider.

AHRI’s Huan Lu documents metabolic resistance in wild radish for first time

In this podcast, we chat with AHRI PhD candidate Huan Lu about his paper “Metribuzin resistance in a wild radish population via both psbA mutation and enhanced metabolism”. The authors of this paper are Huan Lu, Qin Yu, Heping Han, Mechelle J. Owen, and Stephen B. Powles. This paper identifies multiple mechanisms: as well as psbA gene mutation there is a non-target site resistance mechanism of enhanced metabolism. In his current studies, Huan Lu is documenting that this non-target site enhanced metabolism resistance endows resistance to other very different herbicides. This information will become available in Huan’s next publication.

John Broster shares 2019 herbicide resistance survey results

Research agronomist John Broster joins us on AHRI Snapshots this week to give an overview of the annual resistance testing report he releases each year through Charles Sturt University.

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.
