Rust Alerts – 2015 season
Australia: New wheat leaf rust found in WA + cereal rust update
Wednesday October 21, 2015
A new pathotype of wheat leaf rust has been found in WA for the first time this season, prompting a warning that as rust continues to mutate and travel, more varieties may become susceptible and growers need to continue monitoring. The pathotype 104-1,3,4,6,7,8,10,12 +Lr37 was first detected in South Australia in August 2014, and has since spread throughout much of the eastern Australian wheat belt. This pathotype was identified in samples of leaf rusted wheat collected from four separate locations in the northern region of the WA wheat belt in late September 2015. Full details in the Cereal Rust Report (volume 13, issue 4).
Samples of all cereal rusts have been received at the Australian Cereal Rust Survey at the University of Sydney’s Plant Breeding Institute. Full details in the Cereal Rust Report (volume 13, issue 5).
