Explore the GroundCover Supplement: Grain Storage (Issue 119, Nov–Dec 2015), featuring the latest research, grower case studies, and practical strategies for on-farm grain storage. Topics include phosphine resistance, aeration cooling, nitrogen storage technology, grain hygiene, and tools helping growers improve grain quality and profitability.
WA growers will put controlled-atmosphere technology through its paces this harvest,
as part of research into chemical-free alternatives for stored-grain insect control
It seems unlikely there will be a single solution to replace the highly effective phosphine. Rather, a suite of alternatives will be required, applied with tactical precision to extend the life of phosphine and maintain Australia’s export commitment of nil live insects in grain shipments
Replacing oxygen in grain storage silos with nitrogen has proven an effective way to remove insects at all stages of their life cycle, leaving stored grain – be it wheat or canola – preserved, residue-free and subject to no withholding periods.
This GRDC GroundCover feature brings together two articles exploring the benefits of aeration cooling in grain storage, including solar-powered aeration systems and research showing how cooler grain temperatures can reduce insect pressure and help slow phosphine resistance development.

Fumigating with phosphine in unsealed silos does not kill pests at all stages of their life cycle. Repeat fumigations in unsealed silos increases resistance levels
The tolerance for live pests in grain sold off farm is nil. With growers increasing the amount of grain stored on farm, an integrated approach
