Ben White’s Top 10 Tips for Grain Storage

  1. Using phosphine in a silo? It needs to be gas-tight and seal-tested to meet a 3-minute half-life pressure test.
  2. Make sure the pressure relief valve has light hydraulic oil (ISO46 ) in it (wetter is an alternative)
  3. To pressure test Moylan silos, you will need to fit a tubeless tyre valve in the oil fill cap and pressurise with an air compressor to 25mm water gauge (250Pa). The pressure in the silo should not drop below 12.5mm (125Pa) over a three minute period. Birds silos have a tyre valve and you can see the oil level in the semi-opaque u-tube for testing, but for Moylan or DE’s:
    1. To measure the pressure, using a home-made u-tube manometer using a length of clear hose with some water in it.
    2. Or buy a cheap Chinese knock-off differential pressure gauge on ebay – they work just fine!


  4. Keep your sealable silos for clean seed – fill these with seed first and apply fungicide treatments on outload.
    1. This means you can sell this surplus chemical residue free grain if you don’t use it at seeding.
  5. Use your unsealed silos for treated grain and make sure the seed treatment includes an insecticide eg: cypermethrin  (and use this seed first)
  6. Fumigate sealable silos within 3-weeks after harvest – follow the fumigation flowchart
    1. Spread the tablets out – no more than 2-deep on a tray in the headspace or in the ground-level applicator
  7. 2-tablets per tonne capacity (regardless how full the silo is) But check the label to be sure.
  8. Keep silos, hardstands and pads clean and free of grass/weeds – use Dryacide as a structural treatment applied with a Blovac BV22 gun at around 300g per 100T of storage
  9. Aeration works well in WA and is worth considering if purchasing new silos and you have power on site. Note that used properly it will slow or even stop insect reproduction and activity – but will not kill insects.
  10. Call Ben on 1800 WEEVIL (1800 933 845) if you are unsure or just want to check on anything grain storage related.

  • Thanks to all our speakers and attendees at our recent FBG Farmers Updates held on 7th March. An interesting afternoon, with some good topics discussed.





The FBG is a community driven organisation focusing on local issues with a 'ground-up' approach.

  • RESEARCH - Continually working to identify local production and natural resource management issues and then researching, demonstrating and assisting in the implementation of broad scale innovative and sustainable management practices to address these.
  • MARKETING - Continually working to attract project partners and sponsors to the Fitzgerald Biosphere Group.
  • EDUCATION - Working at all levels within the community to increase the awareness and level of understanding of production and natural resource management issues and management options through a range of media.
  • ENVIRONMENT - With a strong Landcare ethic, the group and wider community continues to work towards conserving biodiversity (both at the paddock and landscape scale) recognising the uniqueness of the area and the need for an integrated approach to address production and environmental issues.

Partner Projects

Here are some of the other projects in which the FBG plays a significant role.

Gondwana Link - Visit web site

An exciting and innovative project. The FBG sit on the Gondwana Link Council of partners along with Greening Australia, The Wilderness Society, Friends of the Fitzgerald River National Park, the Mallefowl Preservation Group and Australian Bush Heritage (click on logo for links to partner web pages below). The projects vision is: Gondwana Link will reconnect bushland across the biologically richest corner of Australia, from the forests to the inland.
