Australian Herbicide Resistance Initiative (AHRI) insight #79 - Glufosinate resistance – we know what it’s not
Australia

“There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say, we know there are some things we do not know. But there are also unknown unknowns – the ones we don’t know we don’t know. And if one looks throughout the history of our country and other free countries, it is the latter category that tends to be the difficult ones,” Donald Rumsfeld, US Secretary of Defense 2001-2006.
Man, that’s deep!
It’s wonderful for a scientist to have a hypothesis, do the research, and find that they were on the money. Too easy. And then there are all of those other times when the science doesn’t give the answer that the scientist was looking for. Soul destroying stuff.
During his PhD at AHRI, Adam Jalaludin was working on a population of Crowsfoot grass from Malaysia that was resistant to all of our major knockdown herbicides, glyphosate, paraquat and glufosinate.
Adam was lucky enough to travel to Germany and work in the Bayer lab for six months to try and determine the resistance mechanism of glufosinate.
He found that it was not:
- Reduced uptake
- Reduced translocation
- Enhanced metabolism
- Target site mutation
After all of that effort, Adam and the team didn't find the resistance mechanism, but at least now they have the known knowns. Now they just have to work out what the known unknown is. Hopefully, it’s not an unknown unknown!
