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...

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...

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...
