Key points
– Gas-tight sealable silos should meet the Australian Standard AS2628-2010 for sealing but should only be sealed during a fumigation
– Open sealed silos after fumigation to protect seals and grain quality and, importantly, to prevent excess fumigant absorption

Key points
– Successful pest control in storages depends on combining regular grain monitoring, good hygiene, aeration cooling and correct fumigation practices
– Fumigation results rely on a gas-tight sealable storage to achieve the required gas concentrations and exposure times (C x T) to kill all insect pest life stages
– In larger silos (150 to 2000 tonnes) recirculating gases using a small fan during the fumigation ensures rapid, uniform distribution of phosphine gas
Grain Storage Specialist Ben White explains when to seal and when not to leave silos sealed, and the risks of getting it wrong.
Grain Storage Specialist Ben White looks at the key components and features to consider when buying silos.
Grain Storage Specialist Ben White demonstrates how to do a pressure test to ensure silos meet the Australian Standard 2628 -2010 for gas-tight sealing.
With substantial yields expected across much of the Australian grain growing area and wet weather hampering harvesting efforts, growers are being encouraged to consider how

The fundamental approach to grain storage safety is the same as for all other farming activities. The aim is to have a safe workplace for
Fumigating with phosphine in unsealed silos does not kill pests at all stages of their life cycle. Repeat fumigations in unsealed silos increases resistance levels
