Aeration of stored grain has four main purposes - preventing mould, inhibiting insect development, maintaining seed viability and reducing grain moisture... Without circulation, the air surrounding the grain will reach a moisture (relative humidity) and temperature equilibrium within a few days... Aeration drying using large volumes of air can force a drying front through the grain in storage and slowly remove moisture...

Harvest logistics, access to receival sites, increasing on-farm use of grain and marketing opportunities are changing the way grain is handled and stored... The growth of intensive livestock industries offers growers opportunities to store and market their grain directly to end-users... Growers need to understand that the grain they store will eventually end up in some way in the food chain, either for milling purposes, malting or as a feed source for animals...

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...

Harvest at our place is very relaxed and we have more flexibility which allows us more time to make better decisions on where and when to sell our grain... The complex has significantly reduced the need for infield storage bins and chaser bins, as the trucks don't have to stop when the depot closes, you can buy a 2nd hand trailer for about the same money as 2nd hand chaser bin, and just put more headers in the pdk ( and you can use the trailer for more things)... The last sorghum harvest in March/April, we were getting showers of rain of 1-3 mm every couple of days, and by being able to dry the grain, I estimate compared to neighbours that this saved us about 2 weeks of waiting around...

Grain at typical harvest temperatures of 25-30 C and moisture content greater than 13-14 per cent provides ideal conditions for mould and insect growth (see Figure 1)... There are a number of ways to deal with high-moisture grain - the key is to act quickly and effectively... Cooling before batching:Batch drying (shown ) is one method of dealing with high-moisture grain and aeration cooling in storage can be used to hold grain safely before it can be put through the dryer...

" 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. "..

To assist growers in their efforts to ensure their grain storage practices are safe and effective, the Grains Research and Development Corporation (GRDC) has released two new Fact Sheets... Both fact sheets also contain useful links to other resources and industry experts... The Fact Sheets will be included in the November-December edition of GRDC's Ground Cover magazine, which should now be arriving in growers' mail boxes...

The lesser grain borer is a major pest affecting grains storage in high rainfall zones... A specialist in grains storage systems, Peter Botta of PCB Consulting, is urging growers to regularly check stored grain to avoid damage from insects, mould and humidity... Mr Botta says sampling by sieving for insects when grain is being loaded for delivery allows growers to safely determine whether it is insect-free or requires treatment. "..
