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...

KEYMESSAGES Incorrect use of phosphine since the 1950s, has led to escalating resistance in stored grain insects which threatens the continued use of phosphine at the farm level... 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... When running a trial it is important to: 1...

Cabbage aphids living on the edge.. "Field trials at York and New Norcia in 2013 showed that cabbage aphids - which can cause feeding damage to canola crops in late winter and spring - tend to be distributed along crop edges," Mr Severtson said... Mr Severtson said that as well as highlighting the importance of weed control, the results implied that a border spray might be just as effective at controlling cabbage aphids as a full paddock spray, saving growers time and money...

Hart Winter Walk: virus explained to growers.. Ms Davidson explained that when growers first started reporting widespread damage in June it was initially put down to incorrect herbicide use, but as more crops started showing yellowing leaves a different picture emerged... Crops such as chickpeas, lentils and field peas had not emerged when the first round of the virus hit, but Ms Davidson told growers that pulses will also be susceptible to BWYV in spring...

Ms Davidson explained that when growers first started reporting widespread damage in June it was initially put down to incorrect herbicide use, but as more crops started showing yellowing leaves a different picture emerged... "If crops show patchy infection it may be necessary to control the aphids to prevent further spread of the virus into unaffected parts of crops during late winter and spring.".. Crops such as chickpeas, lentils and field peas had not emerged when the first round of the virus hit, but Ms Davidson told growers that pulses will also be susceptible to BWYV in spring...

Caption 2 : Researcher Dusty Severtson, of UWA and DAFWA, in a New Norcia paddock - one of the sites for field trials researching the distribution of cabbage aphids...

Research shows cabbage aphids living on the edge.. "The new research clearly suggests that infestation of racemes occurs later in the growing season, and that in the weeks prior, the same canola plants host cabbage aphids feeding on leaves in the bottom of the canopy," Mr Severtson said... Mr Severtson said that in some years, cabbage aphids and other species such as turnip aphids could cause widespread damage in late winter and spring by feeding on growing canola shoot tips, causing wilting, flower abortion and reduced pod set...

The combined effects of changes in pest management needs, e.g., through resistance, regulatory activity, market access and registrant indifference with respect to generic pesticides, is placing increasing pressure on grains, pulse and oilseed industries to pursue gaining access to needed alternative pest and weed management options... A potentially serious outcome of the lack of pest management options can be the use of unapproved pesticides or inappropriate choices for pest control... The labels on haloxyfop products used for post-emergent grass control in canola crops are to be amended to overcome concerns that the 'Directions for Use' have the potential to be misinterpreted...

DAFWA researcher Ravjit Khangura standing in a field of canola... Dr Khangura said the main control tactic was to reduce the frequency of host species, such as canola and lupins, and it was recommended growers avoid planting canola on paddocks with high sclerotinia levels during the past three years... "Previous research in WA's northern cropping region has shown that applying a single fungicide spray is often effective in reducing canola yield losses from sclerotinia when the crop is at the 15 to 30 per cent flowering stage (coinciding with the onset of spore release) and conditions are conducive to disease," she said...

Act early to reduce canola virus risk this coming season.. Entomologist Paul Umina of cesar says widespread infestations of green peach aphid (GPA) contributed to the 2014 outbreak of BWYV, which is transferred into canola crops by aphids carrying the virus... SARDI plant pathologist Jenny Davidson said this funding was and will be used in a number of areas, including forensic analysis of canola paddocks; communication to growers and advisers (assisted in SA with an additional $40,000 in emergency funding provided by SAGIT); and preliminary assessment of virus levels in different canola varieties to identify if there are any useful levels of resistance to BWYV for future sowing recommendations...
