SA sowthistle populations confirmed resistant to 2,4-D.. Resistance to the Group I herbicide 2,4-D in sowthistle has been confirmed in South Australia... A major weed of cropping systems north of Dubbo in New South Wales for more than 15 years, sowthistle is now considered a significant emerging weed in southern and western farming systems and will be a focus of the Grains Research and Development Corporation's project on the evolution mechanisms and inheritance of herbicide resistance being led by Dr Chris Preston who is based at the University of Adelaide...

Dr Preston said recent testing of five sowthistle populations from SA had confirmed three populations resistant to solid rates of 2,4-D...

Research has confirmed resistance to glufosinate, glyphosate and paraquat in a crowsfoot grass (also known as goosegrass) population in Malaysia.. The lesson is to add diversity to weed-management systems, rather than simply relying on herbicides alone to control weeds.. There are germinations of crowsfoot grass all year round...

The barley and wheat cultivars bred for the Northern Region are routinely tested for their tolerance to herbicides in three stages... The research is undertaken in weed-free sites in southern Queensland, where yields are compared between those sprayed at a recommended and double rates with the untreated controls for each cultivar... The paper presents the results on the advanced screening of the herbicide tolerance of the new barley and wheat cultivars that have been released in the last five years...

The barley and wheat cultivars bred for the Northern Region are routinely tested for their tolerance to herbicides in three stages... Prior to release and commercialisation, the cultivars are screened with six standard herbicides; Ally, 2,4-D, Glean, MCPA LVE, Starane and Tordon242 for wheat; and Achieve, Ally, 2,4-D, MCPA LVE, Starane and Tordon242 for barley...

The world's first populations of glyphosate resistant wild radish will be announced at Perth's Agribusiness Crop Updates, but researchers stress further cases can be minimised if farmers adopt diverse control strategies... Australian Herbicide Resistance Initiative (AHRI) research has confirmed glyphosate resistance in three populations of wild radish, all from different locations in Western Australia's far northern grainbelt... Caption: GRDC Grains Research PhD Scholarship recipient Michael Ashworth, based at AHRI, says growers should employ a range of tactics to control wild radish and minimise further cases of glyphosate resistance...
