Grain Storage: Grain Fumigation Guide

Grain storage fact sheet: Fumigation

In order to kill grain pests at all stages of their life cycle (egg, larva, pupa, adult), phosphine gas needs to reach, and be maintained at, a concentration possible only in a gas-tight storage.

Key Points

  • To control insects at all life stages the only option is to fumigate in a gas-tight storage.
  • Cool grain temperatures require a longer fumigation period.
  • Aeration fans fitted on gas-tight silos provide a number of benefits including a shorter ventilation period following a fumigation.
