Cereal disease authorities, supported by the Grains Research and Development Corporation (GRDC), say fungicides have an important role to play in disease control but they should be seen as just one component of an overall management strategy... "And while fungicides can be very effective in offering protection from diseases, they must be used judiciously and as part of a multi-faceted management strategy which should also include c ontrolling the green bridge for cereal rusts, attention to the potential risk of stubble-borne leaf disease when deciding on crop rotations, and avoiding susceptible varieties... The Fact Sheet provides information on identifying and understanding fungal diseases, cereal disease diagnosis, fungicide modes of action, foliar fungicide timing, tips for optimal fungicide efficacy, the economics of using fungicides, fungicide resistance, and stewardship...

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...

KEY MESSAGES: Over recent years, CSIRO has developed a range of underpinning technologies and capabilities that will drive major developments in industry profitability and sustainability through yield increases and improved yield stability, quality improvement and stress mitigation into the future... CSIRO has a long track record of making major on-going investment into the genetic improvement of wheat varieties and their agronomy to ensure they fit the target requirements for both the main wheat belt and the High Rainfall Zones of Australia... We outline the state of current research efforts supported by public funds (CSIRO, GRDC) with particular emphasis being given to developments that we believe will assist plant breeders in Australian breeding companies to deliver new high quality, well adapted productive wheats that have the ability to counter major constraint factors...

disease control using fungicides is an economic decision... fungicide timing Factors that influence spray timing recommendations include: growth stage; level of disease; length of the grain fill period; crop yield expectations; whether the region/season is high or low rainfall and if an early seasonal cut-off is expected; the resistance rating of the variety; and the likelihood of disease... Factors to consider in making this decision are: the presence of disease; yield potential; potential loss of yield and quality; commodity prices; and cost of fungicide plus application...

Temperature warming prompts rust warning (VIC).. Victorian grain growers are encouraged to monitor their crops for rust diseases as temperatures begin to rise and as up-front fungicide treatments begin to wear off... More information on cereal rust diseases is available via the GRDC-supported Rust Bust website at www.rustbust.com.au and the GRDC online resource hub at www.grdc.com.au/diseaselinks ...

Watch and be prepared to act on cereal rust.. DAFWA researchers across the WA wheatbelt are closely monitoring volunteer cereals and emerging cereal crops for the presence of leaf rust - as well as other diseases, viruses and pests... Geoff Thomas advises growers and advisers to monitor volunteers, particularly of S varieties such as Stiletto, and to be prepared if fungicide management of leaf rust is required this season...

Although the level of APR is excellent in both Suntop and LongReach Spitfire , it is important to remember that crop management and environmental conditions can have a significant impact on the effectiveness of APR in protecting crops from rust diseases... Looking ahead to the 2015 growing season, we recommend that anyone planning to grow either Suntop or LongReach Spitfire should have a stripe rust management plan well ahead of planting... Other growers should closely monitor their crops of Suntop and LongReach Spitfire and manage the disease as it occurs in consultation with their local advisers...
