S-Metolachlor usage in the northern region

In this WeedSmart webinar, we talk to WeedSmart northern extension agronomist Paul McIntosh and Syngenta’s Field Biology Manager Rob Battaglia about how S-Metolachlor (Dual Gold) works, its efficacy, and what potential resistance problems might be around the corner. They explain what tactics growers should adopt to reduce potential resistance problems on this key grass weed herbicide, referring to the WeedSmart Big 6.
Topics covered include:

Application considerations for maximum efficacy
Incorporation
Effect of stubble
Herbicide solubility
Herbicide binding characteristics
Herbicide safener “EPIVIO-C”

Can intercropping help with weed management?

This WeedSmart webinar outlines the principles of mixing different crops together, and how intercropping may provide weed management options for growers.
Dr Andrew Fletcher is a farming systems scientist at CSIRO who is passionate about the emerging role of diverse cropping systems. He is joined by WeedSmart southern extension agronomist, Greg Condon.
Topics covered include:

Characteristics of intercropping and companion cropping
Australian intercropping data
Canadian intercropping data
Implications for weed management
Examples of in-paddock applications

Mixed farming – does it really help control resistant weeds?

In this webinar, WeedSmart Southern extension agronomist Greg Condon looks at the mixed farming system and explains how the Big 6 principles encourage diverse weed management. Greg focuses on solutions in the medium rainfall zone whilst grower and agronomist Craig Drum focuses on the high rainfall zone.
Both Greg and Craig share real-life examples of clients who successfully controlled resistant weeds by using a mixed farming system, whilst remaining profitable.
Topics covered include:

What the WeedSmart Big 6 looks like in a mixed farming system
How to be profitable whilst reducing the seedbank of resistant weeds
Harvest Weed Seed Control opportunities: baled chaff, chafflines
4 examples of clients who successfully controlled their resistant weeds using mixed farming

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:

Knockdown strategies
Residual chemistry – In-crop and fallow
In-crop herbicides
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
Fallow management
Chipping
Crop competition
Farm hygiene
Rotation planning/fixed rotations
Chaff chutes
Harvest weed seed control
Green-on-green technology and GPS systems

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.

Webinar

How do I make the right decision on using Group Gs?

Choosing and applying the right pre-emergent herbicide can be difficult, particularly if herbicide resistance is becoming a challenge in a no-till system. Join Dr Chris Preston, University of Adelaide (UA) professor weed management and WeedSmart’s Chris Davey as they explain the new Group G chemistry and de-mystifies which Group G works best for winter cropping systems.

Testing all of your herbicides for resistance with Roberto Busi

 
Dr Roberto Busi
Roberto discusses what the current levels of resistance to knock-down herbicides (glyphosate and paraquat) are, resistance to new and old pre-emergent herbicides and resistance to clethodim.
The results are discussed with Peter Newman by analysing the pros and cons of herbicide resistance testing and the value of herbicide efficacy and resistance testing with new herbicides coming into the Australian market from 2021.

Glyphosate Resistance Update with Peter Boutsalis

Dr Peter Boutsalis from the University of Adelaide joins this webinar to discuss tips to optimise the efficacy of glyphosate and when and when not to use the double knock strategy.
Peter also shares the latest results from the GRDC-funded random weeds survey in the Eyre Peninsula and southern Victoria and how the resistance levels in these areas have changed over the last 5 years.
