Take care: rusts persist over winter.. Stem rust requires quite warm conditions and although samples of green bridge survival were reported from eastern Australia in late summer 2011, we can expect disease levels to be low if winter temperatures remain cool to cold... It will be important to monitor susceptible varieties and spray early to achieve adequate control...

Cereal disease management planning critical this season Grain growers throughout the southern cropping region are being reminded of the critical need for cereal disease management planning this season... Growers need to know what to expect with the disease response of each variety of crop sown," said Dr Wellings, whose work is supported by the Grains Research and Development Corporation (GRDC). ".. The ultimate goal of the campaign is to encourage growers to phase out susceptible and very susceptible varieties from their rotation where possible but if these cultivars are grown, then farmers need a management plan ready in advance in case of a rust outbreak...

Develop a plan to maintain rust-resistant crops, growers urged.. CEREAL rust experts are issuing a clear warning to croppers to eliminate use of varieties that are susceptible or very susceptible to rust or they might be risking the resistance that protects many Australian cereal crops from the disease... University of Sydney's Professor Robert Park says growers need to think before they sow this year and consider the implications of managing rust outbreaks in 2013...

Leading plant pathologists Col Wellings (NSW DPI) and Hugh Wallwork (SARDI) will also be at the workshop to discuss with participants the regional agronomic issues of most importance... The small group workshop will cover issues including: cereal growth stages and spray decisions; the impact of environment and day degrees on crop and disease development; understanding where new and old fungicides fit; the development of cost-effective disease management plans; and management strategies for key cereal diseases... The workshop, supported by GRDC and the Rust Bust campaign, is locally sponsored by Bayer Crop Science...

A new cache of rust-resistance genes has been identified in durum wheat.. The new sources will increase diversity for rust resistance in modern varieties - By Dr Gio Braidotti.. Arthur Ernest Watkins may not have the posthumous name recognition of William Farrer but is belatedly leaving his mark on the world, thanks to a treasure trove of rust-resistance genes he left to wheat scientists and a modern world desperate to renew rust defences in wheat, especially against stem rust...

The amount of rust present on this sample means that it could be used to infect a differential set directly, reducing the time for pathotype determinations from six weeks to three weeks... The first report of wheat stripe rust for 2011 was made in early July from southern NSW, while oat crown rust and oat stem rust have been frequently observed since April in crop regrowth and weedy oat populations... The ammount of rust present on this sample menas hat it could be used to infect a differential set directly, reducing the time for pathtype determinations from six weeks to three weeks...

The application of commonly recommended management principles has eradicated a strain of grain-storage insects with strong phosphine resistance located on a Western Australian farm... It is believed to be the first time that elimination of on-farm grain-storage insects with strong phosphine resistance has been scientifically documented and confirmed in Australia and possibly the world... Hygiene treatments used at the Wubin farm to eradicate the resistant RFB population included: pressure washing inside empty silos, storage surrounds, handling equipment and machinery; the application of contact chemical insecticide to kill insects in grain residues at the base of silos and the removal of waste for burial; and treating clean, empty silos with diatomaceous earth protectant to prevent reinfestation...

Professor Park investigated the genetic basis of resistance to rust diseases in cereals at CDL, with a particular focus on how Australian wheat cultivars respond to the dangerous family of stem rust isolates, Ug99... Professor Park tested more than 700 Australian cereal lines using stem rust isolates from Kenya, Ethiopia, Yemen and the US... In addition to research, Professor Park visited other cereal pathology and breeding groups at the University of Minnesota, the University of California, Davis, Washington State University, Pullman Washington, the Virginia Bioinformatics Institute, the Broad Institute and North Carolina State University...

Variety selection skills in focus at new technical workshops Key points: THE GRAINS Research and Development Corporation is funding three new technical workshops for agronomists and farm advisers on variety selection and the National Variety Trials to enable them to provide the most relevant and up-to-date advice to growers... The one-day workshops - titled 'Variety Selection and NVT - Putting science into selection' - will be held in Adelaide, South Australia, on Friday, August 12; Birchip, Victoria, on Wednesday, August 17; and Wagga Wagga, New South Wales, on Friday, August 19... The GRDC's latest technical workshops will enable participants to provide growers with more relevant advice and information on the varieties they are considering as well as factors to consider in evaluating a variety's place in future cropping programs," he said.
