Take a sneak peek at some of GRDC’s storage extension team’s favourite systems.
The grain storage extension team regularly meets growers and industry participants on-farm to run workshops and provide specialist advice. Examples of well-laid-out facilities, smart features, ideas and innovations are highlighted here to help inspire other growers who are investing in grain storage infrastructure.

Key message
– Ground-level fumigation systems are safer for users, but phosphine can be explosive, so precautions are needed to ensure a safe and effective fumigation.
Phosphine fumigation can now be completed using ground-level application systems, which are much safer as the user does not need to climb to the top of the silo. But some key features and precautions are needed for successful and safe fumigation:
– recirculation;
– space for liberation;
– condensation trap; and
– pressure relief for power outage.
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
