Jinyi Chen is an AHRI PhD Candidate studying trifluralin resistance mechanisms in annual ryegrass. Annual ryegrass is a very serious crop weed in Australia causing significant yield loss. The pre-emergence herbicide trifluralin has been used since the 1970s in Australia to control ryegrassThe first trifluralin resistant annual ryegrass plant was reported in 1995. Recently, increasing trifluralin resistant ryegrass populations were reported in Western Australia and South Australia. This was covered in our recent AHRI insight #105 (https://ahri.uwa.edu.au/alphabet-cross-resistance-in-south-australia/).In her research, Jinyi has found that all the four annual ryegrass populations or biotypes tested contained metabolic resistance mechanisms, with target site resistance being involved in two of them. Take a listen to the podcast to learn more about Jinyi's work and some of the possible solutions to dealing with trifluralin resistance. We recently released an AHRI insight on Jinyi's work which you can read here: https://ahri.uwa.edu.au/metabolic-trifluralin-resistance/
