phosphine gas

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...

Growers strengthen their position when their storage facilities allow flexibility with grain handling and timing of sales... As a bonus, many of the strategies used to minimise pest problems also significantly improve storage conditions for maintaining grain quality... Examples include: the ability to have fans automatically step through the 3 important stages of aeration cooling - "continuous", "purge", "protected"; an additional auto function that now excludes high humidity air (>85% RH) in all three of these stages; a setting that can be included that adjusts fan operations to cater for fans fitted to silos with air flow rates higher then the standard 2 - 3 L/s/t flow rates...

Recent ecology research findings which involved trapping flying storage pests across grain growing regions reinforced the value of cleaning up grain residues in storages & equipment.. Examples include: the ability to have fans automatically step through the 3 important stages of aeration cooling - "continuous", "purge", "protected"; an additional auto function that now excludes high humidity air (>85% RH) in all three of these stages; a setting that can be included that adjusts fan operations to cater for fans fitted to silos with air flow rates higher then the standard 2 - 3 L/s/t flow rates... Field tests on farm storages have shown some fans are not delivering required air flow rates...

"It is critically important that growers implement best practice when storing grain, particularly in relation to fumigation," said Peter Botta, grain storage specialist for southern New South Wales, Victoria, South Australia and Tasmania... To control pests at all life stages and prevent resistance, phosphine gas concentration needs to reach 300 parts per million (ppm) for seven days (when grain is above 25C) or 200ppm for 10 days (between 15-25C)... The withholding period is two days after ventilation the total fumigation process requires seven to 10 days...

With an increase in on-farm grain storage in recent years, the Grains Research and Development Corporation (GRDC) has invested in a range of extension material to assist growers... The latest is a GRDC fact sheet, Grain Storage Fumigation - a guide , which outlines how to safely and effectively use phosphine to control grain pests... Aeration fans fitted on gas-tight silos provide a number of benefits including a shorter ventilation period following a fumigation...

The major advantage of fumigation with phosphine (often referred to as bombing or gasing using Fostoxin, Fumitoxin etc) is that insects can be controlled without moving the grain... Phosphine gas moves readily through grain from the point of application... See the full report on insect management in stored grains for: information on phosphine detectors guidelines for staying safe when using phosphine improving effectiveness with phosphine shortcuts for quick treatment of grains..
