Herbicides and stubble – some wash off, some don’t

Which herbicides wash off wheat stubble? Ask any farmer how hard it is to wash the yellow trifluralin stain out of their clothes and you had better be ready for a tirade of domestic hardship! “I just throw them straight in the bin these days”, commented one irate farmer. “I would sooner try and wash […]

Why do pre-em herbicides last so long before resistance bites?

Once in a while, someone comes along and asks a question that you have never given much consideration to. Like, “Why does beer garden beer taste so bad?” or “Why do hotels always give away piles of stuff except for what you actually need, like a toothbrush or a razor?” and “Why do our pre-emergent […]

Glufosinate resistance – we know what it’s not

“There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say, we know there are some things we do not know. But there are also unknown unknowns – the ones we don’t know we don’t know. And if one looks throughout the history of […]

Mini-series: ‘Pre-emergent: A tale of four herbicides’ – Episode 3: ‘Phorate’

  Previously on ‘Pre-emergent: A tale of four herbicides’… In Episode 1, AHRI researcher Roberto Busi turned to the dark side and evolved Sakura resistance in the lab, and then found this had caused cross-resistance to Boxer® and Avadex®, creating the world’s most wanted criminal ryegrass population.

Mini-series – ‘Pre-emergent: A tale of four herbicides’ | Episode 2: ‘Incomplete dominance’

Many of our Australian readers would remember the great TV mini-series ‘Underbelly’ that exposed the underworld of Melbourne and Sydney. It got the whole country talking about Carl Williams and the Moran brothers, and the corruption in the police force. Similarly, our mini-series on pre-emergent herbicides will seek to reveal the underbelly of the herbicide […]

New boy band – ‘The Feathertop Rhodes’

Feathertop Rhodes (FTR) Grass is the boy band of the weeds world. They pop up quickly from obscurity (first to germinate after rain), stress easily at the first sign of trouble (dry), and can be all done and dusted in 18 months (short seed life), not to mention that they are downright annoying as well! […]

Chaff carts – good for the crop and the sheep

So often in life, there are things that conflict with one another. Take the Australian cricket team for example. Social media is great for the social lives of the players, but it is disastrous for their batting. You simply can’t bat all day in a test match when you have the attention span of a […]

Harvester set-up – catch weed seeds and grain

Roger Lowenstein, in his book about Warren Buffett wrote, “Buffett found it extraordinary that academics studied such things. They studied what was measurable, rather than what was meaningful”. When John Broster from CSU and Michael Walsh from Sydney University set out to measure how many weed seeds were entering the chaff fraction in a modern […]

Low dose phenoxy resistance

Once upon a time we used to argue about whether smoking was bad for your health. We don’t argue about that anymore. In the world of weeds, we used to argue whether low herbicide rates cause herbicide resistance. We don’t argue about this anymore. Both low rates and high rates of herbicide can cause herbicide […]
