How a new wheat variety could compete with weeds like Jonah Lomu did on the field

Jonah Lomu stood at 6’5”, weighed 120kg, and ran the 100m in a lazy 10.7 seconds. He could play the power game, the speed game, and he could step. He was the ultimate competitor. Mace wheat, on the other hand, is agile, dependable, and can play the yield game, but its ability to compete with weeds is limited. However, yield is king, and hence Mace has been an extremely successful variety where weeds are under adequate control. What if we could have a wheat variety that could play the yield game and the competition game? What would that look like?

Mini-series – ‘Pre-emergent: A tale of four herbicides’ | Season Finale – Episode 4: ‘Redemption’

They said ‘yeah, it happened in the lab but that will never happen in real life’. The evil Busi said ‘I’m not a bad person, I’m not trying to create a monster, I just found something really bad and felt that I should tell you about it’. The naysayers said, ‘sure, just tell us when it happens in real life, then we’ll believe you’. Guess what, it happened! Dun dun duuuun!!!! Canadian researchers Mangin, Hall and Beckie have found wild oats that are resistant to Avadex®, and have never been sprayed with Sakura®, were found to be Sakura® resistant. This…

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. In Episode 2, Busi teamed up with Todd Gaines and Martin Vila-Aiub. They found that the world’s most criminal ryegrass could share its resistance trait by passing on just one single gene. Fortunately, they found that this gene was semi-dominant. Now, in Episode 3, Busi is at it again, trying to correct his…

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 world. We started this series a couple of years ago and plan to pick it up where we left off. ‘Pre-emergent: A tale of four herbicides’ has the whole of the Australian agricultural industry talking about cross-resistance, P450’s, GST’s, and the sting in the tail…

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! If you think this is just a Queensland problem, think again. This boy band, I mean weed, has risen to fame in recent years as it has spread from its home in Queensland to playing gigs on road verges all over the country. When faced…

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 goldfish! Farming is just the same. There are conflicting farming practices. Often what is good for the crop is detrimental to the sheep, and vice versa. Until now. The humble chaff cart is good for both the crop and the sheep. Ed Riggall is a…
