Proper storage underpins supplier reliability.. Philip Burrill of DAFF Queensland says growers should put the same effort into managing their grain in storage as they put into planting and growing the crop... To hold the gas (for example, phosphine) at the right concentration for the required time (for example, seven or 10 days), the silo does need to be gas-tight...

While growers may be tempted to look at price and storage capacity alone when purchasing new silos, Mr Burrill says aeration and sealability should not be overlooked... "Aeration fitted to seed silos is particularly valuable for maintaining planting seed germination and vigour," Mr Burrill said... Mr Burrill says if growers plan to store grain in sheds, silo bags, bunkers or pads for more than about two months, they should seek advice prior to harvest on options to minimise insect pest build-up in them and look at storage preparations to enable fumigation if required...

The Grains Research and Development Corporation (GRDC) is urging all grain growers to recognise the importance of pressure testing sealable silos before fumigating their grain this season... While more and more growers understand the importance of sealable silos in the use of fumigants, GRDC is still concerned some farmers don't check their seals regularly... In particular two new publications, Fumigating with phosphine, other fumigants and controlled atmospheres , GRDC booklet January 2011 and Pressure testing sealable silos , GRDC Fact Sheet September 2010...

Correct use of fumigant in stored grain urged Australian growers in the fortunate position of having grain to store this year are being provided with timely support to ensure they protect their yields and safeguard their enterprises through the correct use of phosphine for controlling pests in stored grain... GRDC Manager of Extension and Grower Programs, Tom McCue, says phosphine remains the single-most relied upon fumigant to control stored grain pests in Australian grain production systems, but continued incorrect use is resulting in poor insect control and developing resistance in key pest species... To support growers in the effective application of phosphine, the GRDC has produced a valuable booklet, Fumigating with Phosphine, Other Fumigants and Controlled Atmospheres...

The GRDC says there are several key points when you are looking to fumigate stored grain, including effectiveness and safety... A pressure test to determine whether or not a silo is properly sealed involves blowing air into the silo or storage using the aeration fan, an air compressor, hand held blower or vacuum cleaner until a small positive pressure is created... Farmers may think a silo is sealed because it keeps out rain, or because it was originally purchased as a "sealed silo" but in reality even new sealable silos can have construction or design faults resulting in leaks...

In the lead-up to the next winter season harvest, concern is building among grain storage specialists about confusion among growers over what defines a sealable silo for fumigation... Grain storage specialist Peter Botta says some growers, and also some silo manufacturers, have been running into storage quality issues because silos purported to be sealable are still not gas-tight... "If you intend to fumigate then the silo must be gas-tight, and that means a silo conforming to the Australian Standard (AS2628) for gas-tight sealable silos," he says...

With the winter harvest mostly put away, the Grains Research and Development Corporation (GRDC) is encouraging farmers considering fumigating grain stored on farm to do it wisely and carefully... The GRDC says there are several key points when you are looking to fumigate stored grain, including effectiveness and safety... Farmers may think a silo is sealed because it keeps out rain, or because it was originally purchased as a "sealed silo" but in reality even new sealable silos can have construction or design faults resulting in leaks...

Pressure testing a silo ensures it can hold gas concentrations sufficient to kill all insects at all life stages... If the silo has a slide plate outlet that has been tested empty, retest when full to make sure the pressure of the grain doesn't compromise the seal... Common places for leaks are: bottom outlet, aeration inlet seal, damaged lids (caused by the auger when lining it up to fill the silo), stretched springs on latches, between the bottom cone or base and the silo wall joint, the roof and wall joint and where the lid ring joins the roof...
