Mixing herbicides could be the answer to Sakura® resistant ryegrass
Show Notes

AHRI researcher, Dr Danica Goggin and others have recently discovered how ryegrass has evolved resistance to Sakura.  It’s all about GSTs. Not the tax type, rather gluthione transferase (Danica explains in the podcast why the 'S' was dropped!). 

Wheat uses GSTs to detoxify and tolerate Sakura, and ryegrass has now evolved to do the same thing, although the ryegrass is not as tolerant as the wheat.

The researchers found that it is up regulation of GSTs in the roots of the plant that causes the resistance.

Dr Danica Goggin joins us on the podcast to explain these findings.
