Fighting Fleabane!

Gain a better understanding of the differences between species, hear the latest on Big 6 management strategies and learn how to prevent resistance.

The webinar was hosted by WeedSmart’s northern and southern extension agronomists, Paul McIntosh, Greg Condon and Chris Davey. They were joined by regional research experts, Dr Michael Widderick (DPI, QLD) and Dr Harmohinder Dhammu (DPIRD, WA).

Meet the Presenters

Paul McIntosh

Paul is one of WeedSmart’s Northern Extension Agronomists, based in Toowoomba, QLD. With more than 40 years of agronomy experience in the northern region, which offers both winter and summer crop options, Paul is familiar with the unique farming issues and opportunities that come with such diversity in the region.

Greg Condon

Greg is one of WeedSmart’s Northern Extension Agronomists (Vic and NSW), based in Junee, NSW. He runs Grassroots Agronomy with his wife Kirrily Condon. Greg works with growers and industry groups and is passionate about profitable farming systems. Connecting innovative growers with agronomists, stakeholders and researchers is a major focus of Greg’s extension role.

Chris Davey 

Chris became the WeedSmart Southern Extension Agronomist (Vic and SA) in 2020. He has been an agronomist on the Yorke Peninsula for over 25 years, and has seen rapid change with weed resistance over that period due to the continuous cropping nature of that region. Chris started his own consultancy, Next Level Agronomy, in 2023 and has a passion for helping his clients develop non-chemical (IWM) tools to combat annual ryegrass resistance. Chris is a keen promoter of these strategies in the industry.

Dr Michael Widderick

Dr Michael Widderick is a Principal Research Scientist in weed science at Queensland’s
Department of Primary Industries. Michael has over 26 years experience in weed research in
broadacre production systems, spanning weed biology and ecology, understanding herbicide
resistance and development and evaluation of tactics and strategies for the improved control of
weeds.

Dr Harmohinder Dhammu

Dr Harmohinder Dhammu is a Senior Research Scientist with the WA Department of Primary Industries and Regional Development. His recent GRDC funded research identified alternative double-knock strategies that can provide excellent fleabane control, even of mature plants.
