Synergy between herbicides is rare, but extremely sort after and this synergy is often claimed but it takes a specific research technique to confirm the synergy. Australian farmers and agronomists have previously observed synergy between phenoxy herbicides (2,4-D) and PSII herbicides (Group C / Group 3 herbicides such as metribuzin) and now we know why, thanks to this new AHRI research.

About 35 years ago a ryegrass population that had been sprayed several times with Hoegrass® (Diclofop) became resistant to that herbicide and cross resistant to Glean (chlorsulfuron) before Glean® or any other ALS herbicide had ever been used in Australia.
P450 enzymes were suspected to be the cause of this cross resistance but it has taken until now to get the definitive evidence.
A very patient group of researchers led by Heping Han from AHRI, including researchers from Bayer and Zheijiang University in China have identified the P450 gene responsible for cross resistance to herbicides of at least five modes of action.
