, if a pathogen change occurs where the ASR gene is overcome (such as Yr17 in the Western Ausralian pathotype lineage of wheat stripe rust in 2006), the APR gene/s provide back-up resistance, protecting the crop from catastrophic yield losses... In recent years, varieties have been released that lack ASR genes but carry several APR genes pyramided to provide excellent levels of stripe rust resistance as adult plants... Adult plants of LongReach Spitfire are only expected to lose a maximum of 30 per_cent of their leaf area to stripe rust infection...

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...
