Wild radish random AHRI survey of Western Australia

The most recent AHRI random resistance survey by researcher Mechelle Owen reflects exactly these observations. The survey visited 500 fields in 2015 and found only 65 wild radish populations in crop compared to 96 in the previous survey in 2010. There were fewer populations of wild radish found in the crop in the north, and more populations found throughout the rest of the state. As you may expect, herbicide resistance levels in wild radish have generally increased a little between the 2010 and 2015 surveys. Click through to read more.

Has herbicide resistance in ryegrass in WA plateaued?

“The nice part about being a pessimist is that you are constantly being either proven right or pleasantly surprised.” George Will, American journalist, author and Pulitzer Prize-winner.
We are not pessimists at AHRI, but let’s face it, we rarely have good news when it comes to reporting on the level of resistance progression on Australian farms.  We are normally proven right that herbicide resistance levels are continually increasing.
The latest results from the AHRI random ryegrass resistance survey of WA led by Dr Mechelle Owen isn’t necessarily good news, but it’s about as good as we could have hoped.  We know that herbicide resistance levels almost never decrease through time, so the very best that we can hope for is that resistance levels plateau, which is what Mechelle found for a number of herbicides.
