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...

Monitoring populations of cereal rust pathogens to determine which crop varieties show signs of rust infection, which pathotypes (strains or races) are present and where they occur plays an important role in plant breeding for rust resistance around the world... Photo of stem showing wheat rust disease.. After laboratory analysis, growers will be notified of the pathotypes contained in the sample about three weeks later...

Crown rust of oats has become a recurring problem in grazing oats in Australia due to the occurrence of new rust sub-types capable of overcoming the resistance of many cultivars ( Table 1 )... Aladdin remains resistant to all known pathotypes of crown rust in Australia... Given the size and genetic variability in oat crown rust populations in Australia, it is not surprising that these cultivars have usually succumbed to crown rust soon after release...

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...

Rust pathogens have country-wide reach.. The work has clearly shown that rusts migrate freely and rapidly within and between cereal-growing regions of Australia, and even across the Tasman Sea to New Zealand... In 2015, the rust pathotype travelled by wind more than 1600 kilometres and was detected in all eastern states including Tasmania, and in September was detected at four locations in WA (Coorow, Yuna, Carnamah and Woorree)...

Every year since 1919 staff at the University of Sydney have monitored Australian cereal rust populations using samples of rusted plant material collected throughout Australia... The most likely explanation is that the new pathotype has come to Australia from another wheat-growing region... In September 2014 the new pathotype was found in leaf rust samples collected from Mount Hope on the Eyre Peninsula ( Wyalkatchem ) and Moonta ( Axe ) and Port Broughton ( Corack ) on the Yorke Peninsula...
