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 the current levels of resistance to knock-down herbicides (glyphosate and paraquat), new and old pre-emergent herbicides, and 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.
