Australian grain growers are widely acknowledged by their overseas counterparts to be innovative and open to change... The next generation of precision agriculture (PA) technology - variable-rate technology (VRT) - has not caught on so widely or quickly for several reasons, among them being the newness of the technology, perceived cost and complexity and, in some districts, a lack of soil variability in paddocks... The investment program will seek to: deliver increased farmgate profitability; increase measurable grower and adviser confidence in PA technologies, including autonomous and robotic systems; increase timeliness of crop surveillance and repetitive operational practices; partner with one or more machinery manufacturers to bring commercial-incubated autonomous systems to the Australian market; inform and educate regulators and risk underwriters/insurance companies and the finance sector; consider risk mitigation through development of automation and data standards; and invest in the development of the 'social licence' for automation through understanding business risk, farm safety, and benefits for people and the environment...

To minimise the development of glyphosate resistance among weeds, the GRDC has been instrumental in developing a working group on the sustainable use of this key herbicide in Australian cropping... The national Glyphosate Sustainability Working Group includes research and industry representatives from the CRC for Australian Weed Management (CRCAWM), Nufarm, Syngenta, Monsanto, Avcare, University of Western Australia"s WA Herbicide Resistance Initiative, NSW Agriculture, Queensland DPI&F, University of Adelaide and Charles Sturt University... The group is chaired by CRCAWM"s Dr Rick Llewellyn, from UWA...

Opportunities for growers to broaden weeds approach.. Opportunities exist for grain growers in the southern cropping region to more effectively manage weeds in retained stubble systems, according to new research conducted by the CSIRO and funded by the Grains Research and Development Corporation (GRDC)... Caption: CSIRO Senior Research Scientist (Farming Systems) Dr Rick Llewellyn says a new study has highlighted just how costly weed management has become and where there are opportunities to reduce further cost increases...

Opportunities exist for grain growers in the southern cropping region to more effectively manage weeds in retained stubble systems, according to new research conducted by the CSIRO and funded by the Grains Research and Development Corporation (GRDC)... "The data shows very large differences between regions for practices like harvest weed seed control, crop topping and double knockdown which reflects past differences in the levels of herbicide resistance, but we're now seeing resistance issues becoming much more important in all cropping regions," Dr Llewellyn said...

Highlighting the true cost of in-crop weeds.. A new study shows in-crop weeds are an ongoing challenge for Australian grain growers, with overall costs estimated at $3.3 billion annually in terms of lost yield and management methods... Results from the study, available in a report entitled Impact of Weeds on Australian Grain Production , also show growers are mostly keeping in-crop weeds at low densities, despite the increasing presence of herbicide resistance...

Intensive glyphosate use and lack of tillage have been found to be two of the key predisposing factors for glyphosate resistance in broadacre cropping... The National Glyphosate Sustainability Working Group has established an online register of glyphosate-resistant populations in Australia, as well as guides to growers and advisers on how to keep glyphosate resistance to a minimum... Supported by AVCARE and the CRC for Australian Weed Management (Weed CRC), the group brings together glyphosate experience from Monsanto, Syngenta, Nufarm, WA Herbicide Resistance Initiative (University of WA), University of Adelaide, Charles Sturt University, Queensland Department of Primary Industries and Fisheries, Department of Agriculture WA, NSW Department of Primary Industries and the GRDC...

The report, Adoption of no-till cropping practices in Australian grain growing regions, shows WA continues to have Australia's highest proportion of broadacre crop sown using no-till methods - peaking at more than 90 per cent in many districts... Dr Llewellyn says that as well as having the highest proportion of crop sown using no-till methods, WA also has the country's highest proportion of extensive no-till users - 84 per cent expect to use the method to establish their entire crop program over the next few years... In WA, very few no-till users - four per cent - had reduced the proportion of crop sown by no-till methods by reintroducing more cultivation on some paddocks, compared with the national average of 10 per cent," Dr Llewellyn says.
