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...

Storing pulses successfully requires a balance between ideal harvest and storage conditions... Harvesting at 14 per cent moisture content captures grain quality and reduces mechanical damage to the seed but requires careful management to avoid deterioration during storage... Pulses stored above 12 per_cent moisture content require aeration cooling to maintain quality...

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...

The tolerance for live pests in grain sold off farm is nil... With growers increasing the amount of grain stored on farm, an integrated approach to pest control is crucial... Finally the grain requires approximately 50 hours of appropriate quality air each fortnight during storage...

Although we presume there are no insects in grain when being loaded into storage, we generally treat the grain using protectants, or fumigate in gas-tight sealed storage... Fumigating the grain kills any insects present and the aeration maintains grain quality... Always use a mixture of an organophosphate (for example, Fenitrithion , Actellic or Reldan ) with Methoprene (for example, IGR and Diacon ,) either by mixing them together or bought as a 'twin pack' such as Reldan Plus , to protect grain during storage...

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...

Growers strengthen their position when their storage facilities allow flexibility with grain handling and timing of sales... As a bonus, many of the strategies used to minimise pest problems also significantly improve storage conditions for maintaining grain quality... Examples include: the ability to have fans automatically step through the 3 important stages of aeration cooling - "continuous", "purge", "protected"; an additional auto function that now excludes high humidity air (>85% RH) in all three of these stages; a setting that can be included that adjusts fan operations to cater for fans fitted to silos with air flow rates higher then the standard 2 - 3 L/s/t flow rates...

Store carefully to protect grain value.. "As we have both summer and winter harvests, and most growers hold their own planting seed, there is rarely a time when growers have no grain being held on-farm," says senior development agronomist with the Queensland Department of Agriculture, Fisheries and Forestry (DAFF) Philip Burrill... "Monitoring, hygiene and aeration won't solve all your problems, but growers who do these three things regularly and well, backed up by good records, will only need to fumigate for pests about once in every three years," he says...
