AHRI Celebrates 20 years
The Australian Herbicide Resistance Initiative (AHRI) was a GRDC initiative which came about in 1998 under the guidance of Professor Stephen Powles. Last year AHRI celebrated 20 years of GRDC funding, operating as a research group out of the University of Western Australia. This video provides an overview of the beginnings of AHRI, the significant achievements it has had over the last two decades and the direction AHRI is headed into the future.
2,4-D resistance in radish is not metabolic resistance
Tue, 19 Mar 2019
If I took a footballer, say Dustin Martin, and cut off one of his arms, chances are he wouldn’t function too well as a footballer anymore (although knowing Dusty he would probably work out a way around it!)If I then sewed his arm back on so it worked perfectly, he would be back to his Brownlow medal winning best.This is sort of what happens with 2,4-D in wild radish and explains why metabolic resistance is not the mechanism of wild radish resistance to 2,4-D. We now know this thanks to some painstaking research by AHRI researcher, Danica Goggin with funding…
A novel psbA mutation (Phe274–Val) confers resistance to PSII herbicides in wild radish (Raphanus raphanistrum)
Fri, 15 Feb 2019
Wild radish (Raphanus raphanistrum) is a globally important weed of crops. Two atrazine-resistant wild radish populations (R1 and R2), collected fromtheWesternAustralia grain belt, were investigated for resistance to photosystem II (PSII) herbicides.
