AHRI's Dr Mechelle Owen has been collating data from the 2020 random resistance survey. This is part of a national project, with investment from GRDC.
Mechelle has been conducting these random surveys for a number of years and so she shares some of the trends in this interview she has identified from the 2015 survey results compared to these latest preliminary results from Western Australia.
Some of the results available and shared in this interview include the resistance status of barley grass, brome grass and wild radish.
One of the trends Mechelle identified was the spread of SU resistance in brome grass. Initially resistance was only picked up in the northern agricultural region in WA. In 2015, this resistance spread further south into the central and southern regions. This trend was again picked up in the latest 2020 data.
To hear more details about the results and trends, take a listen!
