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...

Zero per cent tolerance levels of GM grain in Australian organic crops makes our growers uncompetitive, Nuffield scholar says.. Western Australian grower and Nuffield Scholar Jemma Sadler sees GM varieties having an increasing role in weed management around the world, but notes the need for further education and communication to ensure a workable coexistence with non-GM growers... For example, Jemma visited a farm in North Dakota, in the US, that produces non-GM soybeans, even though 95 per cent of North Dakota's soybeans are GM. "Buffer zones of 30 centimetres [in effect, no buffer] are maintained between GM and non-GM soybeans and other GM crops, and strict farm hygiene is adhered to in all farm machinery and storage facilities," Jemma wrote in her Nuffield report...

The management change required to reduce the impact of these weed issues can be summarised as an 'increased focus on driving the weed seed bank down over time using a more diverse range of weed management tactics.'.. The purpose of the project is to have weeds extension professionals work with northern region weeds researchers to reduce their time load on extension and communication activities... Working alongside northern Weeds Researchers from DAFF Qld, NSW DPI, NGA, GOA and the CQGSG, project officers will ensure they are intimately familiar with the latest weeds research outcomes of the groups...

The availability of GM canola has prompted BCG (formerly the Birchip Cropping Group) to examine weed and herbicide-management options associated with different canola systems to support decision-making among growers in Victoria and NSW... To date, the study has found that while adoption of RR canola levelled off when conditions switched from dry to wet, the glyphosate-resistance trait can boost weed management options across an entire rotation system... Mr Hausler identified benefits associated with RR canola in his IWM system, including: excellent weed control in dry and wet conditions, including annual ryegrass, Indian hedge mustard and white ironweed; profitability; ability to rest Group A herbicides in the RR canola as well as in subsequent cereal crops; a saving of $30 to $40/ha in herbicides in subsequent cereal crops due to clean paddocks; and better yields than TT canola and similar to Clearfield varieties...
