AHRI’s Dr Roberto Busi talks about his finding of velocity resistant wild radish in this podcast. 

It’s not great news for growers – but knowledge is power. 

At the end of 2019, Roberto Busi started a new herbicide resistance testing service based at UWA. Growers and agronomists sent in about 500 samples of ryegrass for testing as well as 121 samples of wild radish. Two of these wild radish populations, sampled by agronomists, had survivors to Velocity® and Roberto embarked on extensive glasshouse and field testing.

Resistance testing and using diverse tactics, as found in the WeedSmart Big 6, continues to be key in preserving chemistries into the long-term.
