Risks of canola-on-canola cropping

GRDC Podcast

Show Notes

92,000 hectares of canola has been planted into canola stubble this year. Blackleg pathologist from the University of Melbourne, Associate Professor Angela Van de Wouw, Western Australian agronomist Geoff Fosbery, and plant breeder Raymond Cowley explain why the risks of canola-on-canola far outweigh any short-term benefits.

The Disease Management Extension Network (DMEN) is a GRDC investment bringing together plant pathologists, extension specialists and behavioural scientists to improve disease management outcomes for Australian grain growers and advisers.

Alex Conway grew up surrounded by agriculture, machinery and problem-solving, watching his family business evolve from a small operation run out of a garage into a nationally recognised grain storage technology company. What began as helping program aeration controllers and fit GPS guidance systems as a kid has turned into a career combining agricultural engineering, grain storage extension and a passion for helping growers better manage risk and protect grain quality. Today, Alex balances his role at Control Unlimited with his work on GRDC’s Grain Storage Extension team, supporting growers across Australia through workshops, industry events and practical on-farm advice.
