What’s next in the North for weed control?
Angus’ presentation focuses on the current practices for weed control in Queensland, highlighting the need for an integrated approach to weed control in order to preserve existing herbicides.
Topics covered include:
Residual chemistry – In-crop and fallow
Problem weeds moving forward
Peter discussed some of the tactics currently used for weed management in the Liverpool Plains of Northern NSW, and what the future might hold.
Topics covered include:
Current levels of resistance/tolerance in summer and winter weeds
Rotation planning/fixed rotations
Harvest weed seed control
Green-on-green technology and GPS systems

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.
How to make the right decision on using Group Gs in the Northern cropping system
Group Gs have a place in northern cropping systems both in summer and winter crop scenarios. We ask Andrew Somervaille to explain Group G use in both systems and the most optimum use of different Group G products given the range of seasonal conditions in the northern cropping region.

Considerations for pre-emergent herbicides with dry sowing
In this webinar, we focus on what factors influence the residual control of weeds by pre-emergent herbicides with a focus on Trifluralin, Sakura and new-to-market herbicides.
Join Chris Davey, YPAG and WeedSmart Extension Agronomist and Mark Congreve, ICAN Senior Agronomist as they assess the sowing issues in South Australia and discuss strategies on using pre-emergents.
Factors covered include
Rainfall forecast (after application)
Characteristics of the herbicide

Farmer questions answered on Group G herbicides and optimum application temperature
In this follow-up to last year’s webinar on Group Gs, Dr Chris Preston, University of Adelaide, Professor of Weed Management and WeedSmart’s Greg Condon focus on farmer questions around Group G herbicide use.
They explain the new Group G chemistry in simple terms and address questions around what temperature range provides optimum herbicide efficacy.
