Perth Update Event 2022 – Dr. Mike Ashworth

The cost of constantly evolving weed infestations in Australia is staggering. Growers spend around $2.5 billion every year on the problem, with annual ryegrass the number one ranking Australian cropping system weed.

In WA, a series of trials over several years has been studying the interaction between wheat seeding timing and pre emergent herbicides choice on annual ryegrass seed production, with some helpful results on offer. In this podcast, we talk to Dr Mike Ashworth, research agronomist, who’s heading the trials with the Australian Herbicide Resistance Initiative at the University of WA about the trials and his top tips for reducing annual rye grass and wild radish seed production in wheat using crop competition.
