Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... Overall, 60-70 per cent of flour is used in traditional flat breads, 20-25 per cent of flour is used in western style breads and 5-10 per cent is used in cakes and biscuits... In summary, canola varieties sown 2-3 weeks earlier than normal (early to mid April) can be grazed in winter prior to bud elongation (usually providing 600-800 dse grazing days/ha) and recover with no impact on yield or oil...

Assess blackleg risk to canola yields before spraying crops.. Assess blackleg risk to canola yields before spraying crops Canola growers in the southern cropping region must determine the potential for significant yield losses caused by blackleg infection before investing in and applying post-emergent treatments... Key points contained in the fact sheet include: "It is important for growers to monitor crops each season so they know the extent of blackleg infection and can make more informed management decisions," Dr Marcroft said...

Growers need to be confident that they will incur significant yield losses before investing in this form of control," Dr Marcroft said. "..

Adapting our current practices and varieties to focus on managing the three key phases of crown rot (survival, infection and yield loss) will determine the impact this disease has on your crops in the future... Yield achievement in the presence of crown rot (Figure 2) is perhaps a more useful means of comparing varieties rather than the extent of yield loss associated with infection (Figure 1) as a variety with the smallest yield loss may not always be the highest yield achiever... The agronomy of durum production has not been extensively evaluated in such a western environment due to limited commercial production in the region primarily based around concerns over the high susceptibility of this crop to crown rot...

Two durum and 10 bread wheat varieties were evaluated in the presence of added or no added crown inoculum across 11 field sites in 2013... Where no additional CR was added EGA Gregory had similar yield to other varieties at sites with low background levels of crown rot but was between -0.52 t/ha (Suntop ) to -0.37 t/ha (Sunguard ) lower yielding at sites with medium-high background levels of crown rot... Some newer wheat varieties have a measurable improvement in their tolerance to crown rot but these current levels are not a complete solution to crown rot...

Crown rot is a priority wheat disease in the northern grains region... Crown rot infection requires moist soil, and the past few years have caused problems for growers by increasing the disease's prevalence... Crown rot "We spend most of our time trying to minimise crown rot inoculum levels soil water is by far the biggest factor in the impact of this disease on profitability," Dr Simpfendorfer says...

Head loss in barley can cause major economic losses in the coast regions of Esperance in WA or the lower Eyre and Yorke Peninsulas of SA. Head loss is climatically dependent and controlled by strong genetics and environmental interaction... On-site screening for head loss is critical for the results relevant to barley industry... The outputs of the project will provide genetic materials and molecular tools for the barley breeders to develop new malting barley varieties with minimum risk of head loss for barley growers...

Overall, 64-70% of the cultivar x herbicide combinations resulted in no significant yield losses at both recommended and double rates... 9-10% of the cultivar x herbicide combinations had significant yield losses at the recommended rate in one or more trials... In summary, 70% of the wheat x herbicide combinations and 64% of the barley x herbicide combinations had no significant yield losses at both the recommended and double rates...
