They said it couldn’t be done – climbing Everest, flying to the moon and even deep-frying Mars bars. We were also told that we couldn’t reverse herbicide resistance. In the majority of cases, the experts are right – herbicide resistance is permanent, and we thought that was the case for all resistant weeds.
Until now…

Pre-emergent herbicides are a valuable tool to underpin crop competition and suppress weed seed production in-crop, but when growers also want to harness the power of retained stubble they often run into a sticking point where pre-emergent herbicide efficacy is compromised. Most growers and advisors are aware that products such as trifluralin are quite tightly bound if they contact stubble during application, however, AHRI research associate Dr Yaseen Khalil has been working to shed light on the behaviour of the newer pre-emergent herbicides and how to use them in no-till, stubble retention farming systems.

We once thought that the genetics of eye colour was simple. Both parents have blue eyes, therefore, all of their children will have blue eyes. Easy peasy! Then science progressed and we realised that it isn’t actually that simple because several genes are involved. The genetics of herbicide resistance was simple. One parent is resistant to a herbicide, therefore, all of the offspring will be resistant because the gene is dominant or semi-dominant. This is true for almost all cases of herbicide resistance and was easy to understand. Until now. Click to read more about PhD student Jinyi Chen’s research.

Ever tried walking out onto a 10-pin bowling alley? It’s generally not pretty, often resulting in a rapid and undignified descent to ground level…But that’s just what we need to get pre-emergent herbicides to slide off stubble and into the soil, which can be difficult in higher residue systems. Rainfall is obviously a key driver in leaching herbicides from stubble before they dissipate, but as we all know rain can be an unpredictable beast. Fortunately, research has shown that some pre-emergent herbicides require far less rainfall to move off stubble and into the soil where they can control germinating weeds.
