Barley stripe rust (Puccinia striiformis) is currently an exotic disease and barley grass stripe rust can attack some susceptible barley varieties... Stem rust survives the summer mainly on volunteer wheat, barley, triticale and some grasses including common wheat grass and barley grass... The most effective way to control the rusts of barley is to grow varieties with resistance or avoid growing those that are rated as very susceptible or susceptible to each disease...

The stripe rust that infects barley grass is either the wheat-attacking form or a second form that is specialised to barley grass... A form of stripe rust that is specialised to barley grass, known as barley grass stripe rust, can infect some barley cultivars, but the threat it poses is minor... Recent GRDC-funded tests in Mexico have shown that Australian barley cultivars are generally susceptible to the barley form of stripe rust, which means this exotic disease poses a significant threat to the Australian barley industry...

The potential for epidemic development can be gauged by the amount of disease in the lower canopy... Cereal seed treatments are widely used throughout the Northern Grains Region (NGR) to control or suppress a broad range of diseases... With a range of diseases that are more difficult to control and a grain fill period less predisposed to drought stress there may be more benefit to strobilurins in barley crops rather than wheat, though more work is needed to verify this statement...

Temperature warming prompts rust warning (VIC).. Victorian grain growers are encouraged to monitor their crops for rust diseases as temperatures begin to rise and as up-front fungicide treatments begin to wear off... More information on cereal rust diseases is available via the GRDC-supported Rust Bust website at www.rustbust.com.au and the GRDC online resource hub at www.grdc.com.au/diseaselinks ...

Growers do not have access to varieties with resistance to the key exotic pests and disease... The project will proceed in two phases... The project is about optimizing pesticide sprayapplications by: identifying spray technologies and spray settings with low risk of spraydrift, applying pesticides in accordance with latest knowledge about pest behaviour in response to pesticides andtherefore minimizes the risk of target pests developing resistance, and by using pesticides with documented efficacyagainst target pests...

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.
