Trifluralin resistance explained, with Steve Powles

AHRI Snapshots

This podcast looks at trifluralin resistance, with AHRI Director Stephen Powles. The results out of a recent AHRI, entitled Novel Tubulin Mutations Conferring Resistance to Dinitroaniline Herbicides in Lolium rigidum are the primary focus. Steve explains that this study clearly and comprehensively establishes that target site resistance to dinitroaniline herbicides, such as trifluralin, can be endowed by a mutation changing the alpha tubulin gene at amino acid 243, changing Arg to either Met or Lys. He explains how this works, as well as looking at how common trifluralin resistance is; the differences between target site and metabolic resistance, as well as the implications of these findings in the field.You can read the paper in full here: https://ahri.uwa.edu.au/publications/novel-tubulin-mutations-conferring-resistance-to-dinitroaniline-herbicides-in-lolium-rigidum/But you might like to listen to the podcast first, as its one of the more tricky concepts to get your head around!Take a listen!Music: bensound.com
