The path to healthy winter crop yields starts with diligent control of the green bridge of over-summering weeds and volunteer cereal plants, according to Dr Rohan Rainbow, Grains Research and Development Corporation (GRDC)... The GRDC's annual St Patrick's Day reminder to control the green bridge has taken on extra importance this year after a wet fallow period... Log in or register to leave a comment...

Professor Powles, who heads the Australian Herbicide Resistance Initiative (AHRI), based at the University of Western Australia, told growers and advisers at the Grains Research Update in Perth that 86 per cent of maize and 94 per cent of soybean crop fields in the US are sown with Roundup Ready (RR) crops... After RR was introduced, growers switched to using a single mode of action - glyphosate... A major increase in glyphosate-resistant weeds has occurred, Professor Powles says...

While the focus was on developing generic models to address questions related to when to attempt eradication and when to contain and mitigate, the focus was on developing decision support tools to achieve optimal management strategies for controlling the parasitic weed branched broomrape ( Orobanche ramosa )... We applied the decision tool to branched broomrape to choose between alternative management strategies and it was parameterised by collaborating with the branched broomrape eradication team... The research provides a move forward in decision theory techniques for ecological systems as previous methods have not dealt with the issue of partially observable states adequately...

Partners in Grain (PinG) New South Wales recently organised a study tour to Western Australia to observe farming system innovations that may be adapted for farming operations in the eastern states... "Growers often work in isolation and travelling with peers is a fantastic opportunity for sharing ideas and knowledge," Ms Thomas said... In the post-tour survey: 81 per cent of the group said they had a greater understanding of the use of data to drive business decisions 59 per cent felt their knowledge of advanced farming systems had improved 63 per cent believed they now had a better understanding of the benefits and limitations of herbicide resistance and weed control 27 per cent said they had acquired more knowledge of management practices to prevent herbicide resistance..

Seed Destructor on course for commercial production The Harrington Seed Destructor is edging closer towards commercial production, offering an additional strategy in the grains industry's battle against herbicide resistance in weeds... The trials and evaluations are being overseen by Australian Herbicide Resistance Initiative (AHRI) researcher, Dr Michael Walsh, who says the trial sites will be revisited as soon as the break in the season occurs to assess the efficacy of the unit in reducing annual ryegrass emergence. ".. Dr Walsh said the trials and demonstrations in the southern cropping region during December involved 15 sites over 16 days and a travelling distance of 4000 kilometres during that time. "..

Weeds specialist Dr Ford Baldwin of Practical Weed Consultants in the US thought Roundup Ready soybeans were a miracle when they became available in 1995: "The technology was superior to anything we had seen," he said... Dr Baldwin said that if you look at the technology now in the US, resistance is found within all the key weed species, meaning some growers have had to resort to hand-weeding and tillage to deal with tolerant plants... He said, many southern US growers are turning to glufosinate (Group N herbicides, such as Basta and Liberty ) to achieve broad-spectrum weed control...

Dr Graham Brodie working on his prototype microwave weed killer... Dr Graham Brodie from the University of Melbourne has developed the technology, using microwave horn antennae mounted on a trailer... The potential advantages of microwaves are that they generally kill weeds immediately and there are no residues, so potentially restrictive withholding periods for crops would not apply...

Destroy weed seeds with narrow windrow burning.. Narrow windrow burning could be the answer for grain growers looking for a simple, low cost way of destroying weed seeds after harvest... Narrow Windrow Burning involves adding a chute to the harvester (top) to direct the chaff into a narrow windrow, which is later burnt (bottom) to destroy weed seeds...
