Fumigation in gas-tight storage is the only option for control of grain pest insects at all stages of their life cycle... But successful fumigation requires knowing how much phosphine gas to apply, when to apply it and the length of time needed for an effective kill... The fact sheet has been developed in consultation with grain storage specialists, including Peter Botta, of PCB Consulting, who says that in order to kill eggs, larva, pupa and adult grain pests, phosphine gas needs to reach, and be maintained at, a concentration possible only in a gas-tight storage...

Mr Botta says now is the time to check on stored grain and plan for storage of grain from this year's harvest... "Sampling grain as during out-load for delivery and sieving for insects gives the grower greater confidence the grain is free of insects or indicates whether it needs to be treated if insects are present," Mr Botta said... "Keeping grain at the right moisture and temperature levels will reduce the likelihood of insect infestations, but stored grain still needs to be sampled regularly and monitored for any changes," he said...

The lesser grain borer is a major pest affecting grains storage in high rainfall zones... A specialist in grains storage systems, Peter Botta of PCB Consulting, is urging growers to regularly check stored grain to avoid damage from insects, mould and humidity... Mr Botta says sampling by sieving for insects when grain is being loaded for delivery allows growers to safely determine whether it is insect-free or requires treatment. "..

Most hazards in grain storage can be avoided by getting the right systems in place... Use a gas mask when applying chemicals such as phosphine, and only use chemicals in pressure-tested, gas-tight storages... The GRDC's representative on the PIHSP, Tom McCue, says best-practice health and safety needs to become part of the culture of primary industries to save lives and reduce the impact on families and communities...

In the lead-up to the next winter season harvest, concern is building among grain storage specialists about confusion among growers over what defines a sealable silo for fumigation... Grain storage specialist Peter Botta says some growers, and also some silo manufacturers, have been running into storage quality issues because silos purported to be sealable are still not gas-tight... "If you intend to fumigate then the silo must be gas-tight, and that means a silo conforming to the Australian Standard (AS2628) for gas-tight sealable silos," he says...
