AHRI researcher Qin Yu recently teamed up with a team of Chinese scientists to show that a case of metabolic resistance in Barnyard grass in China is likely associated with epigenetics. There were no changes to the genetic code of the plant, but there were changes in the expression of a specific P450 gene.

The first resistance to HPPD herbicides in wild radish has now been discovered by AHRI researchers led by PhD candidate Huan Lu. Wild radish is just the third weed in the world to evolve resistance to this group of herbicides. The wild radish in this research was resistant to several other groups of herbicides which may have led to metabolic resistance to HPPD.

Merv Hughes was not a fit-looking cricketer. Merv was a notorious consumer of food and alcohol, and it showed! Despite this, he was a successful professional sportsman. Mitchell Johnson, on the other hand, was the epitome of a fit, healthy fast bowler. But who had the better bowling average? You guessed it, big swervin’ Mervin!! 28.38 compared to Johnson’s 28.4. Ok, we’re splitting hairs here, but you get the picture, how fit you look is only part of the story.
If you grew 2,4-D resistant radish in pots on its own, and compared that to the good old susceptible radish of yesteryear, you would find that the resistant ones are a bit smaller overall, slightly shorter, have smaller leaves and they are slightly more dormant so they germinate a bit later.
You would think that all of this would add up to a less fit wild radish plant that is less competitive with our crops.
That’s exactly what AHRI researcher, Dr Danica Goggin, thought when she observed these differences in her research to work out how 2,4-D resistance works. So she studied it. Click through to learn what she found!

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.
