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...

SARDI Cereal Pathologist Dr Hugh Wallwork has received reports of stripe rust and leaf rust in wheat, and net form net blotch and spot form net blotch in barley... While similar, the symptoms of stripe rust will appear in a line (top), whereas leaf rust appears as single pustules or more random groups of pustules (bottom)... The complication is that while Mace is not as susceptible to leaf rust, the disease has been seen in Mace, so it's not just a matter of any rust on Mace wheat being stripe rust."..

Choose resistant varieties to ward off stem rust.. While fungicides may work on leaf rust and stripe rust, which affect the leaves more than the stems, they are less effective on stem rust, especially in thick canopies where they may have trouble penetrating and contacting the stems... Figure 3: Stem rust appears on both the leaves and stems of the plant running parallel to the long axis of the leaf or stem...

With winter crop sowing well underway across New South Wales, wheat growers are being reminded to stay vigilant on stripe rust... NSW Department of Primary Industries (DPI) senior plant pathologist Dr Steven Simpfendorfer has two key messages for growers as the season progresses - monitor crops regularly for any signs of rust infection and tailor fungicide strategies to varietal resistance level, rainfall zone, growth stage and seasonal conditions... Speaking at the Grains Research and Development Corporation (GRDC) Grains Research Updates earlier this year, Dr Simpfendorfer said the stripe rust risk was always present and urged growers not to drop the ball on management, particularly around minimum disease standards...
