More information: Australian Glyphosate Sustainability Working Group, www.glyphosateresistance.org.au - By Sharon Watt.. The GRDC is urging growers to be on the lookout for any weeds that should be controlled by glyphosate but which survive... "This is a huge concern to Australian grain growers because this highly competitive weed has been becoming a major problem in reduced-tillage farming," says Associate Professor Chris Preston, chair of the Australian Glyphosate Sustainability Working Group and leader of the University of Adelaide team that confirmed the result...

Feathertop Rhodes grass not to be taken lightly.. An established weed of the northern cropping region, feathertop Rhodes grass is now becoming a problem for grain growers in parts of the southern region... The GRDC has just published a fact sheet to assist growers with management of this tufted annual grass which grows up to one metre tall and has a distinctive seed head of between seven and 19 feathery spikes...

Northern region Grains Research Updates coordinator John Cameron reflects on the vast changes that researchers and growers have implemented over the past two decades, and the one problem that just will not go away - weeds.. No-till has become crucial to northern grains production but faces a major weed-control challenge... In the short term, the no-till system will be defended by tactics such as pre-emergent herbicides, double knock using paraquat, and the use of tillage when weeds cannot be or are uneconomical to control using herbicides...

Strategic tillage renews on-farm profit potential.. The trials, led by Dr Yash Dang through the University of Queensland and the Queensland Department of Science, Information Technology and Innovation, showed that strategic tillage has the potential to lift both grain yields and gross margins, as well as maintaining soil health... Strategic tillage targeting a suite of weeds - fleabane, sow thistle, African turnip and feathertop Rhodes grass - has also enabled the Jensens cut seeding rates...

New wheat changes weed management options.. James Clark, Grains Research and Development Corporation (GRDC) northern panel chair said Elmore CL Plus , a new Clearfield wheat released by Australian Grain Technologies (AGT) gives growers another tool to combat problem weeds... "There is a discount in moving from a prime hard to hard variety but it may be worth it for the opportunity to reset the system, control weeds and use residual chemicals in the fallow, a practice that would normally lock growers out of wheat that year," he said...

The manual offers an overview of FTR and its biology as well as practical advice on all aspects of FTR management including control tactics, post-emergent and residual herbicide options, the use of crop rotations, advice on chemical groups to include in a management program and implementation of an effective integrated control strategy... The manual's recommendations are based on the latest FTR research findings on herbicide efficacy, effects of strategic tillage on seed placement in the soil profile, seed bank viability at differing burial depths, effect of different implements on FTR emergence and the impact of crop rotation in FTR management... A copy of the Integrated Weed Management of FTR manual can be downloaded at www.grdc.com.au/IWM-FTR-2014 ...

With harvest in full swing, many growers are putting into practice harvest weed seed control (HWSC) systems to help tackle weeds - which are at high levels this season... Many growers are probably already familiar with the HWSC options of narrow windrow burning, chaff carts, the Harrington Seed Destructor and the Bale Direct system (baling all chaff and straw material as it exits the harvester)... The chaff deck places the chaff exiting the sieves of the harvester on to permanent wheel tracks, and it is estimated that up to 70 of these units are being used across WA's South Coast region this harvest...

Multiple herbicide resistance in weeds poses a bigger problem than glyphosate resistance in Australian and global cropping systems, and the only way forward is diversity in weed control practices... "There are more than 60 countries where scientists are reporting herbicide resistant weeds and lately we have seen a big problem with weeds resistant to many different types of herbicides," he said... Dr Heap said the problem of multiple herbicide resistance in weeds was compounded by a lack of discovery of new herbicides with alternative modes, or sites of action (MOA) in recent years...
