Ahri Snapshots

In this podcast, Jessica Strauss chats with then AHRI PhD Candidate Gayle Somerville about her paper “Modeling the impact of harvest weed seed control on herbicide resistance evolution”.The modelling in this paper was a component of the PhD research of AHRI PhD student Gayle Somerville, who is now a postdoc at Arhus University in Denmark.Harvest weed seed control (HWSC) is a term that describes a range of techniques to capture and destroy weed seed on standing weed plants infesting crops at the time of grain harvest. HWSC techniques have become adopted by many Australian grain growers, with AHRI research in HWSC led by Michael Walsh (now at University of Sydney). HWSC is currently being evaluated in other parts of the world. The objective of HWSC is to target weed seed at grain harvest to minimise weed seed injection into soil seedbanks and reduce weed densities over time.It's well understood that herbicide resistance evolution in weeds would be much slower if any herbicide resistant individuals were ann
