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...

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...

The Australian Government has announced additional funding of $29.7 million over six years for the CRCNPB... Grains industry biosecurity management and stored grains protection will continue to be a priority for the CRCNPB. Chief executive officer Dr Simon McKirdy says efforts will continue to extend the life of the stored-grain fumigant phosphine and to find alternatives to phosphine - particularly non-chemical options such as nitrogen... "A better understanding of how insects are surviving between harvests will also be important in improving fumigation management," Dr McKirdy says...

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...

"It is critically important that growers implement best practice when storing grain, particularly in relation to fumigation," said Peter Botta, grain storage specialist for southern New South Wales, Victoria, South Australia and Tasmania... To control pests at all life stages and prevent resistance, phosphine gas concentration needs to reach 300 parts per million (ppm) for seven days (when grain is above 25C) or 200ppm for 10 days (between 15-25C)... The withholding period is two days after ventilation the total fumigation process requires seven to 10 days...

Fumigation in gas-tight storage is the only option for control of grain pest insects at all stages of their life cycle... But successful fumigation requires knowing how much phosphine gas to apply, when to apply it and the length of time needed for an effective kill... The fact sheet has been developed in consultation with grain storage specialists, including Peter Botta, of PCB Consulting, who says that in order to kill eggs, larva, pupa and adult grain pests, phosphine gas needs to reach, and be maintained at, a concentration possible only in a gas-tight storage...

" Date: 06.03.2012 Grain checks equal grain cheques!.. Grain checks equal grain cheques!.. Some farmers get their grain into the silo and breathe a sigh of relief, but it does have to be carefully looked after in storage or you can do your dough, not to mention waste the efforts of harvest," Mr Botta said. "..

Dr Freebairn says bringing together decision support aids and 65 years of daily rainfall, temperature and radiation data gathered by 4500 Australian Bureau of Meteorology (BOM) weather stations, overlayed with the Queensland Government's Silo data base, ranks among his career highlights... "A rich history of each property is reflected in the long term weather data and if you were manually flicking through your data page by page, year by year you could build up a picture of probabilities to answer the questions you have in mind... "The App and the aids it contains allow growers to quickly and easily answer questions such as the probability of well-timed planting rain or unfortunate frost events."..
