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...

Brome grass needs multi-pronged attack.. When herbicides are put under pressure resistant weeds are quickly selected for, such as this population of brome grass... Break crops need to be employed with other management tools including: high seeding rates at sowing for improved competition with brome grass plants; effective herbicide choice with correct rates, droplet size and timing; regular resistance testing if herbicide failure is suspected; retaining or sourcing clean seed for future use; and monitoring brome grass levels in all paddocks while planning future use...

While smart chemical and crop rotation management is commonplace for grain growers across Australia trying to get on top of weeds, controlling weed seeds at harvest has also gained popularity... Western Australian grower Matthew Hill from Esperance is one of an increasing number focusing on harvest residue management, but with a difference... From there I went to Shepparton in Victoria to see Dr Graham Brodie, where we looked at microwaving and perhaps denaturing seeds directly out of the combine using microwave technology," he says...

As a grain grower near Mingenew in the Geraldton port zone I'm well aware of the threat posed by wild radish to the financial viability of growers in my region... Recognising the problem, collaborative local research has been conducted investigating herbicidal control of wild radish, and the results will provide guidance to Western Australian growers this season... After identifying wild radish as the main priority for funding in 2012, the research - involving a number of researchers and farm advisers - set about trying to find new herbicide tankmixes for wild radish control as an alternative to using the newer herbicides such as Velocity (bromoxynil and pyrasulfotole) twice in a growing season...
