Testing all of your herbicides for resistance with Roberto Busi

In 2020, 600 ryegrass were tested for herbicide resistance at UWA by Dr Roberto Busi. In this webinar, Roberto, who is an active member of the AHRI team, will highlight the key results obtained by screening ryegrass samples with a large number of herbicide options including mixtures.

 

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.

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
