    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.

Pre-emergent herbicides in stubble – strike or foul?

Wed, 6 Mar 2019

Ever tried walking out onto a 10-pin bowling alley? It’s generally not pretty, often resulting in a rapid and undignified descent to ground level…But that’s just what we need to get pre-emergent herbicides to slide off stubble and into the soil, which can be difficult in higher residue systems. Rainfall is obviously a key driver in leaching herbicides from stubble before they dissipate, but as we all know rain can be an unpredictable beast. Fortunately, research has shown that some pre-emergent herbicides require far less rainfall to move off stubble and into the soil where they can control germinating weeds.

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.
