Research from the GRDC Grain Storage Extension team has revealed a safer and more effective way to apply diatomaceous earth (DE) in empty on-farm silos. DE, a flour-like dust made from fossilised aquatic organisms, works as a non-chemical control by dehydrating insects through abrasions to their waxy coating.

Diatomaceous earth (DE) is a proven solution for pest control in grain storage, but its effectiveness depends on uniform application. Recent research highlights that battery-powered and petrol-powered blowers with venturi attachments deliver superior distribution compared to traditional compressed-air methods.
