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...

For example, at Dubbo 407 mm of rain fell on 68 days (39 days >1.0mm) between 01 June and 30 November, compared with a long-term average of 282 mm on 43 days (34 days >1.0mm)... The pattern encouraged rapid vegetative growth of crops and was ideal for the build-up and spread of the major chickpea pathogens... Ascochyta blight (AB, caused by Ascochyta rabiei ), Botrytis grey mould (BGM, caused by Botrytis cinerea ), Phytophthora root rot (PRR, caused by Phytophthora medicaginis ) and Sclerotinia rot (caused by Sclerotinia sclerotiorum and Sclerotinia minor ) were widespread and severe in many crops...

For example, at Goondiwindi 416 mm of rain fell on 57 days (44 days >1.0mm) between 01 June and 30 November, compared with a long-term average of 263 mm on 34 days (26 days >1.0mm)... Ascochyta blight (AB, caused by Ascochyta rabiei ), Botrytis grey mould (BGM, caused by Botrytis cinerea ), Phytophthora root rot (PRR, caused by Phytophthora medicaginis ) and Sclerotinia rot (caused by Sclerotinia sclerotiorum and Sclerotinia minor ) were widespread and severe in many crops... Timely and thorough applications are critical...

Sustainable management of most cereal diseases can be achieved by avoiding susceptible and very susceptible cultivars... A graphical representation of the relative effect of increasing pre-sowing crown rot inoculum levels, as determined using PredictaB, on grain yield loss (%) in three cereals in seasons with below average combined September and October rainfall (left) and above average rainfall for the same period (right) using 26 data sets collected in Victoria and South Australia during the years 2005 to 2010 (Hollaway et al. 2013)... There will be a greater need to monitor and apply foliar fungicides in wetter seasons...

Blackleg severity was reduced and canola yield increased by Impact when applied either as in-furrow or foliar applications and by foliar application of prothioconazole... Incidence of Sclerotinia was assessed for all treatment plots two weeks before harvest... Crown canker severity was assessed on 35 plants per plot using a 0-4 scale (0 = no disease, 4 = 75-100% canker) three weeks prior to harvest...

The initial adoption of Flexi-N was driven by the convenience of storage and handling, improved speed and uniformity of application, and reduced labour requirements when applied with pesticides... Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 37.. The trials suggest that applying fungicides in large droplets at water rates between 60-80 L/ha will be beneficial in a range of seasons in the Mingenew area...

* Bannister oats are subject to Plant Breeders Rights Caption: GRDC's Kwinana West Port Zone Regional Cropping Solutions Network (RCSN) group funded trials into fungicide management of septoria leaf blotch on Bannister oats last year, carried out by ConsultAg's Ashton Gray and Garren Knell... Using fungicides to control septoria leaf blotch in Bannister oats may improve crop yields when good spring rain is received, but can't be relied on to reduce grain staining at the end of the season... Ashton says, given the trials were deliberately carried out where disease pressure was high, it appears that using a double-spray can be economic in high yield-potential crops in a year with a wet finish and when infection occurs at/after stem extension...
