In this new segment, WeedSmart Shorts, our expert agronomists around the country interview experts on topics in a ‘Question and Answer’ video format.
Simon was kind enough to be our first guest and Jana covers lots of important points with him throughout the interview. Above, you can find what questions are covered if you’d like to jump to one of the specific topics highlighted.
Simon says there has been uptake by his clients of glyphosate tolerant canola in South Australia, but there has been a varied response.
“We are finding that some are wanting to try a paddock, some are wanting to sit back and see how it goes. So, it is probably very similar to what happened in Victoria when it rolled out there as an option,” he says.
South Australian farmers in the past have been able to control the weeds with the existing canola options they have, says Simon, but what they are finding now is there is an increase in clethodim resistance, particularly at higher rates and so that is what is likely to be driving the decision-making process around what other canola options are available, such as RR canola.
While it is exciting to have another option for SA growers, Simon says it is critical that growers know their ryegrass resistance status before committing to planting glyphosate tolerant canola.
“Testing is the backbone behind the decision making around canola options and so once we’re aware of what herbicides still work effectively, that’s where we’re able to make a good, informed decision.”
Simon said it was important to know what works on ryegrass across the whole spectrum of herbicide groups.
“An example is, I did some testing for a new client recently and one of his populations came back as 80% resistant to glyphosate. Now, had we not done that test and put glyphosate resistant canola into that paddock, we would’ve been facing a disaster, but because we had that information on hand, we knew what our options were and what they weren’t,” Simon says.
RIM: Ryegrass Integrated Management
RIM is a hands on, user-friendly decision support software that allows farmers and advisors to evaluate the long-term cropping profitability of strategic and tactical ryegrass control methods, on the long-term and at the paddock scale. RIM lets you test your ideas: How can you run your ryegrass down and profit up? New rotation? New technique?

Crop selection, rotation tips and post-harvest spraying
On the last podcast for 2018, we spoke with Dr Haydn Kuchel, who is CEO & Head of Breeding at AGT Breeding. AGT Breeding develops new field crop varieties.
Haydn Kuchel,wheat breeder,AGT Rosworthy. 0428 817 402.
Haydn talks to us about AGT-run crop competition trials and how they influenced their breeding programs. We also learn about crop varieties coming online in the future. Finally, we checked in with AHRI and WeedSmart extension agronomist, Greg Condon.
He gives an overview of crop sequencing and rotation, as well as providing some tips on post-harvest spraying.
