Catalogue: NVT Online Papers
Destroy wheat volunteers that will harbour rust in autumn... For susceptible to intermediate varieties, if there is a high risk of local carryover associated with 'green bridge' (see below), use fungicide at seeding or spray fungicide at stem elongation to prevent early infection... If crops have not received early fungicide protection, commence monitoring for stripe or leaf rust at early stem elongation (first node stage, Z31 Figure 1) and apply fungicide at the first sign of infection, according to Table 3...

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...

Wheat stripe rust was detected across the northern grains region of Western Australia in 2015 - and thankfully all stripe rust samples processed were the original 'WA pathotype' (134 E16 A+)... It is possible that the eastern pathotypes derived from the original WA pathotype of wheat stripe rust with virulence for Yr17 and Yr27 may have hitched a ride back across to WA at the same time as the leaf rust pathotype... Any pathotypes of wheat stripe rust in WA with virulence for Yr17 need to be detected as soon as possible to enable the majority of growers who rely on Yr17 for stripe rust protection to respond with fungicides in a timely manner...

Now available are Grains Research and Development Corporation (GRDC) Tips and Tactics publications for wheat leaf rust, stem rust and stripe rust, which have the potential to slash farm incomes during an outbreak... GRDC General Manager Crop Protection Ken Young said careful monitoring of crops was crucial and identification of rust infections in the previous year could help determine the threat of rust and other diseases in the following season... The Tips and Tactics publications, available at this link , include information about conditions that favour the diseases; disease identification; management strategies; frequently asked questions; submitting a suspected rust sample; and links to further information...

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...
