Complex mechanisms at play in 2,4-D resistance

In Danica Goggin’s latest research, she identified a very plausible resistance mechanism in two wild radish populations. She then went on to test the translocation theory in another nine 2,4-D resistant populations of wild radish from WA. Danica characterised the resistance profile of the 11 resistant populations to find that resistance to 2,4-D and dicamba appears to be capped. Looking more closely at these 11 resistant populations also revealed that while all 2,4-D resistant populations were also resistant to dicamba, the level of resistance to the two herbicides varied.

Chickpeas can have the competitive edge after all

There are few herbicide options for sowthistle control in chickpea crops, making the perfect recipe for a good ol’ sowthistle blowout. Despite all of this, the latest research by Michael Widderick, Adam McKiernan and Greg Harvey from QDAF with GRDC investment is finding that chickpeas can win the competition against sowthistle if they stack their deck.

Modeling the Impact of Harvest Weed Seed Control on Herbicide Resistance Evolution

In this podcast, Gayle Somerville explains how she evaluated the value of HWSC in minimising the rate of herbicide resistance evolution in her research paper “Modeling the impact of harvest weed seed control on herbicide resistance evolution”. Her modeling clearly showed the benefit of HWSC in minimising resistance evolution and that there’s a real benefit in having the diversity tactic of the non-chemical HWSC in minimising the rate of resistance evolution.

How a key gene in barley enabling it to access deep-stored water was discovered

In this podcast, we chat with InterGrain Research Officer Hannah Robinson. Not too long ago she completed her PhD at the University of Queensland, looking primarily at identifying the genes controlling root architecture in barley. Some significant discoveries were made during this time, including identifying a key gene in barley that enables the plant to access water stored deep in the soil during droughts.
