Digging deep into 2,4-D resistance

Thu, 12 Jul 2018

Synthetic auxins might be the oldest kids on the herbicide block but that doesn’t mean they are well understood. In fact, there are very large knowledge gaps that researchers like AHRI’s Dr Danica Goggin are trying hard to fill in a bid to find ways to overcome resistance to this herbicide group in weeds such as wild radish.

Earlier papers by Gaines et al 2012 Weed Technology and Goh et al 2016 Pest Management Science,  documented a glyphosate resistance Echinochloa population from the irrigated north-west Ord River irrigation region of Western Australia. AHRI PhD student Sou Sheng Goh studied this population for his PhD research. Among other studies, Goh completed excellent work to identify the mechanistic basis of glyphosate resistance in this Echinochloa population. Goh examined for but did not find EPSPS resistance gene mutations and/or EPSPS gene amplification. Thus Goh established that glyphosate resistance in this particular resistant biotype is NON-target site based.
