Rather than putting phosphine in the headspace, some silos are equipped with a ground application system. Phosphine is applied into a chamber at ground level and disperses’ through the grain via an opening into the bottom of the silo and/or via a sealed recirculation system. The important thing is that the phosphine has a large […]

In silos over 150 tonne a sealed recirculation system is ideal to disperse the gas in a shorter time frame. The key is that the silo is gas-tight – that is, meets a five minute, half-life pressure test and the recirculation system won’t compromise that seal in the future. For more information see ‘Fumigating with […]

The AS2628 was developed to form a common definition of a gas-tight, sealable silo which is suitable for fumigation. For a silo to meet the AS2628 it must perform a five minute, half-life pressure test. If a silo meets this pressure test, it will hold phosphine gas and other fumigants at a concentration high enough […]

The first thing to ask yourself is do I want the option to fumigate in the silo? If the answer is yes then you will need a gas-tight, sealable silo that meets the Australian Standard 2628. Ensure the manufacture or importer can guarantee this by performing a five minute, half-life pressure test once the silo […]

Where do insects live and can I clean up to keep them away from my storage? A Insects typically like warm dark area’s with a source of food. Common places to find insects are in leftover bags of grain, under hoppers, in machinery where grain gets caught and under rubbish around storages. Cleaning grain storages, […]
