Personal profile


Mike Ashworth is an Research Agronomist with the Australian Herbicide Resistance Initiative. Mike grew up on a family farm in Western Australia, before being trained as an Agronomist. Mike worked as an Elders agronomist before being employed with the Western Australian no till farmers association.

Roles and responsibilities

Herbicide resistance, farming systems research, improving no-till systems, herbicide efficacy in no-till systems, Integrated weed management.

Current projects

I am currently managing the agronomy research at the Australian Herbicide Resistance Initiative (AHRI) studying the optimal use of integrated weed management techniques to minimise unintended herbicide resistance or lifecycle adaptations in economically damaging weed species. I am also running a project to develop a novel in field herbicide resistance assay to screen annual weed populations for herbicide resistance. Both projects are funded by the Grains Research and Development Corporation (GRDC)

Industrial relevance

Herbicide resistance, IPM and soil seed bank decline, Herbicide technology


Herbicide resistance
Weed control
Conservation farming/no-till systems
Agronomy and cropping systems
Precision agriculture
