Cereal rust strains provide clues to resistance.. Cereal rust pathotypes - which are races or strains of the disease that vary in their ability to overcome resistance genes in cereal varieties - are common in most Australian wheat, barley, oat, rye and triticale crops... All barley cultivars carrying this resistance gene are currently resistant to leaf rust in Western Australia, while in eastern Australia, some are moderately susceptible to susceptible...

Wet summers that favour the growth of volunteer wheat can provide a favourable environment for leaf rust to build up, increasing the threat of rust in the following season... Eliminating volunteer/weed wheat plants (the 'green bridge') over summer/autumn can reduce the carry over of leaf rust, and other rust inoculum, between seasons... The chances of a leaf rust epidemic are greatest following a wet summer...

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...

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.

Dr Grant Hollaway in a paddock of self-sown barley heavily infected with stem rust and leaf rust, which provides a 'green bridge' for these rust pathogens to survive between cropping cycles... The region comprises a tapestry of overlapping crops at all growth stages, providing an ideal environment for rust to flourish... Growers should also consider the use of fungicide applied to seed or fertiliser in districts known to have rust surviving on volunteers...

Adult plant resistance is a useful trait to consider in variety selection, especially for rust resistance... Key points Adult plant resistance (Apr) to cereal fungal diseases provides protection in a crop's post-seedling stages (typically between tillering and booting, gS20-gS49)... Apr can complement a fungicide strategy by protecting, from rust, those parts of the plant most responsible for yield...
