The potential for epidemic development can be gauged by the amount of disease in the lower canopy... Cereal seed treatments are widely used throughout the Northern Grains Region (NGR) to control or suppress a broad range of diseases... With a range of diseases that are more difficult to control and a grain fill period less predisposed to drought stress there may be more benefit to strobilurins in barley crops rather than wheat, though more work is needed to verify this statement...

Inspect barley crops now to prevent leaf rust losses.. New findings of barley leaf rust in Western Australia's southern cropping regions have prompted a warning to growers to inspect their crops now for the costly disease and spray infected crops early... Department of Agriculture and Food (DAFWA) plant pathologist Kith Jayasena, whose research is supported by the Grains Research and Development Corporation (GRDC), said the disease had been confirmed this month in barley crops at South Stirlings and Woogenellup in the Great Southern and at several locations in the Esperance region...

Infection is favoured by wet weather and temperatures of about 27 o C. Plants are most susceptible at the seedling stage and late in the season when the crop begins to 'cut out'... Infection on cotyledons, leaves and bracts first appears as small, circular brown, grey-brown to tan spots which vary in size from 1-10 mm... Under favourable conditions the disease is most severe on lower leaves and least severe on upper leaves, unless leaves are affected by premature senescence...
