Storing oilseeds is more difficult than storing cereal grains as they are more susceptible to quality deterioration and have limited insect control options... The decision to store oilseeds requires a planned approach, careful management and a suitable storage system... Moisture content in oilseeds must be lower than cereal grains because the oil content increases the risk of moulding and quality damage...

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...

The capacity of grain bags varies with bag size, which generally ranges from 40 to 90 metres long, and anywhere from 100 to 300 tonnes depending on the type of grain and how much the bag is stretched during filling... Storing grain at higher moisture content in bags not only compromises grain quality but increases the risk of grain swelling and splitting the bag... Take the bait:Reduce mice numbers by setting up bait stations along the grain bags and keep an eye on creases in the bag as mice tend to attack there first...

Fumigating with Phosphine, other fumigants and controlled atmospheres.. Phosphine remains the single-most relied upon fumigant to control stored grain pests in Australian grain production systems, but continued misuse is resulting in poor insect control and developing resistance in key pest species... Fumigating with Phosphine, other fumigants and controlled atmospheres covers topics such as pressure testing, silo safety and the application of both phosphine and other options...

There is only an extremely small risk of WSMV being spread through seed... Wider row spacings and higher plant populations will result in a more even and shorter flowering period and harvest, due to reduced tillering (Thomas et al 1980)... It is highly likely that plant population should be somewhere in the range 100 to 150 plants/m 2...

Agri-Science Queensland grain storage specialist Philip Burrill says for grain storage, three key factors provide significant gains for both grain storage pest control and grain quality - hygiene, aeration cooling and correct fumigation. ".. By ensuring that machinery and equipment used to handle grain, including headers, augers, field bins, truck bins, silos and other storages are clean to prevent insect pest contamination of newly harvested grain you have a huge head start. ".. In regards to applying protectant insecticides to grain, a number of grain buyers are now requiring that grain and grain products have nil chemical residues, so you should always check with potential buyers and handlers before you treat with commercially available products such as Fenitrothion, Reldan, and IGR. "Do not use any of these chemical insecticides when storing oilseeds or pulses...
