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...

Grains industry recognises rust expert Colin Wellings.. The award was presented to Prof Wellings this week at the GRDC Adviser Update at Young, NSW, where he was addressing researchers, scientists, advisers, agronomists and growers on the latest developments in cereal diseases... During the period he has assumed research and advisory roles with the Australian Cereal Rust Control Program, working in partnership with the GRDC. Over the past 30 years, Prof Wellings has been responsible for Australia-wide monitoring of the stripe rust pathogen (strain identification), genetic studies of resistance in wheat to this pathogen, and assisting directly with disease control by providing breeding support to all wheat breeding groups in Australia...

In Australia, more than 80 per cent of all stored grain is treated with phosphine, which means it is the chemical most in contact with insects, creating the greatest chance for insects to develop resistance... Two projects under the CRC for National Plant Biosecurity are looking at the genetics of insect resistance to phosphine to understand the development of resistance and to rapidly identify resistant insects... One of the greatest threats to emerge is the development of resistance to phosphine in the lesser grain borer (Rhyzopertha dominica), one of the most common pests of stored grain...

Grain growers are being urged to start monitoring this year's emerging crops for rust and prepare a rust-management plan following early detections of severe stem rust in volunteer wheat crops in the southern region... "In developing a rust-management plan, growers should also revisit the susceptibility of the varieties they have selected to grow and tailor their action plan to the level of resistance present.".. "There is plenty of help available if growers are not sure how susceptible their varieties are or which is the best approach to take - check with your local agronomist, plant pathologist, your regional variety guide or visit the Rust Bust website ( www.rustbust.com.au ) or the National Variety Trials website ( www.nvtonline.com.au )...

Early rust samples analysed by the Cereal Rust Laboratory have sparked concerns that stripe rust, and possibly leaf rust, may hit for wheat crops across southern Queensland and northern and central western NSW this season... One sample from Marombi wheat at Dunedoo, NSW was infected with leaf rust, and a sample of stripe rust was taken from Tobruk triticale at Young, NSW," Dr Wellings said. ".. Selection of rust-resistant varieties , teamed with control of the green bridge of volunteer plants over summer and,strategic fungicide use are the three clear strategies we need growers to take on board," Dr Rainbow said.
