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...

With the appearance and spread of mutants of the Ug99 lineage originating in Africa, most of the stem rust resistance genes used in Australian wheats are now vulnerable to stem rust... Progeny tests showed that six plants were Lr resistant and two plants were susceptible... Stocks with several hundred critical seeds carrying the 6Ae chromosome in a ph1bph1b genotype have been produced...

Grain growers are being urged to start monitoring this year's emerging crops for rust and prepare a rust-management plan following early detections of severe stem rust in volunteer wheat crops in the southern region... "In developing a rust-management plan, growers should also revisit the susceptibility of the varieties they have selected to grow and tailor their action plan to the level of resistance present.".. "There is plenty of help available if growers are not sure how susceptible their varieties are or which is the best approach to take - check with your local agronomist, plant pathologist, your regional variety guide or visit the Rust Bust website ( www.rustbust.com.au ) or the National Variety Trials website ( www.nvtonline.com.au )...

Stem rust is characterised by reddish-brown, powdery, oblong pustules that can affect all plant parts... KeY POINts seasonal conditions are the key factors driving outbreaks of stem rust... Background When conditions favour a stem rust epidemic, it can be a very damaging disease that can cause complete crop loss in susceptible wheat varieties...

Middle: Leaf rust pustules are smaller than stem rust and rarely appear on the back of the leaf... It is unlikely that all growers will apply adequate fungicide at the first sign of rust and keep the infection sufficiently under control so that the disease will not spread to neighbouring properties... Equally it is unrealistic to expect that all growers will sufficiently monitor or destroy volunteers growing between seasons to ensure that those volunteers will not harbour rust infections which may be responsible for starting new epidemics...

Dr Grant Hollaway in a paddock of self-sown barley heavily infected with stem rust and leaf rust, which provides a 'green bridge' for these rust pathogens to survive between cropping cycles... The region comprises a tapestry of overlapping crops at all growth stages, providing an ideal environment for rust to flourish... Growers should also consider the use of fungicide applied to seed or fertiliser in districts known to have rust surviving on volunteers...

Only one sample of wheat stripe rust was received from the western grains region in 2009, 2011 and 2012 ( Figure 1 )... Leaf and stem rusts of wheat, oats and barley were also reported in WA this season, along with reports of wheat stripe rust in some crops of Mace ... It is important that growers continue to monitor their crops throughout the growing season and submit samples of any rusts found to the Australian Cereal Rust Survey for pathotype identification...
