The campaign - called the Rust Bust - is supported by the GRDC and gives growers tips on more effectively managing rust and adopting a 'select and protect' strategy... "This year, wheat growers in eastern Australia face an unprecedented risk of stripe, stem and leaf rust because of increased inoculum levels in crops during 2010 and the potential for carryover on volunteer plants, called the green bridge, thriving following high summer rainfall," he says... "A rust outbreak in Australia has the potential to slash farm incomes which is why it is so vital we plan our response to rust this year at the beginning of the season, rather than waiting for a rust outbreak to occur and then planning a control approach," he says...

A new campaign launched today by the Australian Cereal Rust Control Program (ACRCP) is encouraging growers to be proactive and plan their 2011 rust management strategy now in response to the worst disease risk in nearly 40 years... "This year, wheat growers face an unprecedented risk of stripe, stem and leaf rust because of increased inoculum levels in crops during 2010 and the potential for carry over on volunteer plants, called the green bridge, thriving following high summer rainfall," he said... "The ultimate goal of the campaign is to encourage growers to phase out susceptible and very susceptible varieties from their rotation where possible but if these cultivars are grown, then farmers need a management plan ready in advance in case of a rust outbreak...

Grain producers have been urged to give stripe rust a greater priority when selecting triticale varieties following the discovery of a new strain of the airborne fungus... The varieties Jackie, Breakwell, Speedee, Abacus, Prime 322, Kosciuszko, Hillary and Madonna are all vulnerable to the new pathotype," Dr Wellings said. ".. The strain was first found on a sample of Jackie triticale at Bingara, near Moree in northern NSW. "It was the first rust sample I received for the season and it took a while for us to determine it was a new strain," he said...

Farmers who have the capacity to run a profitable business amid challenging circumstances such as increased seasonal variability tend to have common characteristics, the 5th World Congress on Conservation Agriculture was told... David Gray, a development officer with the Department of Agriculture and Food, Western Australia (DAFWA), studied the business behaviours of resilient farmers in WA and identified six common characteristics: scanning the business environment for opportunities, changes, trends; engaging in contingency planning; building flexibility into the business; actively building relationships with others including growers, agronomists, suppliers; and continually experimenting and making innovations... The first characteristic common to all was the practice of scanning the business environment for changes, trends, emerging opportunities or threats...

The virtual deregulation of the barley market in eastern and southern Australia has also brought new buyers into the market... Dr Fettell said the new varieties being considered for southern NSW - Buloke, Baudin, Flagship and Vlamingh - had all out-yielded Schooner, but none met the malting grade with the same consistency. ".. The Western Australian variety Vlamingh, which had been bred specifically for WA, showed variable yields in southern NSW, Dr Fettell said, but another variety on the horizon, Hindmarsh, consistently out-yielded Schooner by 10-15% across a range of sites...

It can be reported that no new pathotypes of wheat stem rust, wheat leaf rust, barley leaf rust or oat stem rust have been detected to date... Cultivar responses are not expected to change... It was less common in northern NSW; the pathotype associated with LongReach LincolnA (64 E0 A-) has been recovered at low frequency, but does not appear to have had an adverse effect on LongReach LincolnA and BolacA during the season; and the 'Yr17-27' pathotype was first reported in October (Cereal Rust Report, Volume 8, Issue 7, available at http://sydney.edu.au/agriculture/plant_breeding_institute/cereal_rust/reports_forms.shtml )...

More than 20 Australian researchers, along with US and European scientists, have spent four years trying to understand what will happen to grain crops if carbon dioxide (CO2) levels rise by 50 per cent over the next 40 years... Six projects make use of Horsham's Australian Grains Free Air CO2 Enrichment (AGFACE) facility, where trial plots of wheat, field peas and canola are grown with the CO2 levels predicted to be in the atmosphere in 2050... We use the information to estimate the effects of different temperatures and rainfall, plus CO2 levels on crop yields...
