Catalogue: GRDC Research Summaries
Foliar diseases are a major constraint to national wheat yield stability, and cause annual industry wide costs ranging from yield loss and down grading of grain, to chemical control expenses and removal of preferred varieties from recommendation lists... The importance of wheat diseases to Australian cereal producers was highlighted in a GRDC commissioned study that was published in September 2009... The study by Murray and Brennan (2009) on the economic impact of wheat diseases estimated that stripe rust caused current.....

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...

Nipper lentils and PBA Rana faba beans require additional fungicide sprays due to ascochyta resistance breakdown... Ascochyta blight in chickpea cultivars and breeding line; reactions range from Resistant to MR-MS, requiring different spray strategies... Multiple sprays were required later in the season to maintain disease control...

Overall, barley diseases have the potential to cause very significant costs for farmers... Incidence is 30 per_cent frequency in 30 per_cent of the area, so that the average incidence of the disease affecting the crop is 9 per_cent... Overall, breeding contributes more than 25 per cent of the control for 14 diseases, cultural methods for 32 diseases, and pesticides for six barley diseases...

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...

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

Control blackleg early to minimise canola yield losses.. Department of Agriculture and Food (DAFWA) plant pathologist Ravjit Khangura, who conducts Grains Research and Development Corporation (GRDC) supported research in WA, said it was important to control blackleg early in the season to minimise yield losses... "Blackleg can attack the crop at any stage, but early seedling infections - especially up to the four or five-leaf stage - are the most damaging in terms of the development of severe stem cankers and yield loss," she said...

We conducted 56 replicated plot experiments on a range of integrated disease management (IDM) strategies under this project aimed at reducing losses and refining management of these diseases... Three replicated trials were conducted in 2007 with 24 different treatments evaluated for the control of CR in both a bread wheat and durum variety... In collaboration with CAS, we tested stubble samples from 312 paddocks in northern NSW for levels of CR and CRR during this project...

Consecutive cereal crops can reduce yields.. Dr Roger Lawes from CSIRO and Associate Professor Michael Renton from the University of Western Australia (UWA) developed the model as part of a project funded by the GRDC and the Department of Agriculture and Food, WA (DAFWA)... Dr Lawes says LUSO indicates that growing two consecutive cereal crops without a break crop can cause yield losses of between 10 and 20 per cent, while three or more such crops result in even higher yield penalties...

The Lower Eyre Peninsula survey showed most paddocks had internal blackleg infection levels below 10% unlikely to suffer a yield or oil content penalty... Current varieties have a number of resistance genes if blackleg overcomes one resistance gene, other resistance genes remain effective and so the crops should not become completely susceptible... Final grain yield after slashing was similar in all varieties (about 0.8 t/ha average), except CB1206 (0.2 t/ha)...
