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 allocation of resources for the control of barley diseases, both at the grower level when deciding whether to control a particular disease and at the national level when allocating funds for research and development, depends on an assessment of the losses caused by those diseases... The figures provide key insights into the importance of barley diseases in Australia... Barley diseases cause an estimated current average annual loss of $252 million, or $66.49 per hectare, to the Australian barley industry...

Net blotch is expected to be at damaging levels in Western Australian barley crops this year, particularly in high rainfall areas, but growers can reduce the risks by adopting an integrated disease management approach... "There is a high risk of damage to 2014 barley crops due to carry-over of the disease from last year, heavy stubble loads and warm conditions forecast for coming months," he said... "Both forms of net blotch have become more prevalent in WA in recent years and were damaging last season, particularly in south coastal regions."..

Foundation for Arable Research (FAR) Australia managing director Nick Poole said initial results with the SDHI's modes of action were proving promising against a range of barley diseases such as net blotches and scald as well as wheat diseases such as yellow leaf spot and Septoria Tritici Blotch... "New products with new modes of action are not immune from resistance development to prolong their activity and that of our existing triazole products we need to use them judiciously and in combination with other control options," Mr Poole said... "Systiva potentially changes the management strategies for controlling net form net blotch (NFNB), spot form net blotch (SFNB) and scald in susceptible cultivars and situations, since this new SDHI has good persistence on foliar diseases...
