The new Gunnedah population on the left looks healthy, showing it has a much higher level of resistance compared to the sample in the centre which is known to be susceptible, and the original resistant Moree population on the right... The world's third case of glyphosate resistant liverseed grass has been confirmed in northern New South Wales, seven years after the first two cases were confirmed from east of Moree... "While this is only the third confirmed case of glyphosate resistant liverseed grass in seven years, it comes from a new area and has a much higher level of resistance than previous populations," stated Tony Cook, Technical Specialist (Weeds) with NSW Department of Primary Industries...

The work showed that Touchdown Broadacre Tm (TD- BA) offered ~96% control but another formulation of a Group M herbicide at comparable use rates only controlled 10% at 52 days after application (DAA)... A group M herbicide @ 2lt/ha followed by a double knock of Sprayseed Tm offered moderate improvement in control (61% control @ 52 DAA)... The summary of the results of this trial is shown in Graph 1 below...

At present five weeds are confirmed glyphosate-resistant: barnyard grass, liverseed grass, windmill grass, annual ryegrass and flaxleaf fleabane... A fleabane module has also been added, but may need to be modified when the genetics of resistance is determined... The project has provided the growers and advisers of the northern region with a new suite of chemical and non-chemical tactics that have been integrated into strategies to prevent or manage the important issues of glyphosate-resistant grasses and multiple-resistant wild oats...
