Post-Harvest Integrity

Post-Harvest Integrity and Research

Post-harvest grain biosecurity.


Maximise the value, integrity, and competitive advantage of Australia’s post-harvest supply chain.

Indicators of success


Strategy for extending the useful life of phosphine to support market access outcomes for Australian grains.


New knowledge underpinning strategies to manage phosphine resistance is accepted by peers through publication.


Standardised detection and measurement of resistance to phosphine is accepted by end-users.


Improved phosphine resistance management practice both on-farm and in all sectors of the post-harvest grains supply chain.


New tools to optimise chemical applications in grain storage are adopted by end users.

Post-Harvest Integrity Research Projects

CRC50059: Fumigation TechnologyMr James Darby

This project investigated options to overcome the cause of deficient fumigation, sustain the life of phosphine and enable the effective application of new fumigants. It will develop an integrated more

CRC50060: Cool Grain FumigationDr Greg Daglish

Increasing applications of phosphine to stored grain in silos that leak, or grain stored under the wrong conditions, has caused problems with insect pests building up resistance. Proof is needed more

CRC50089: Grain Insect EcologyDr Greg Daglish

Resistance to phosphine in target pests threatens market access for Australian grain. While the grains industry is now attempting to develop an effective and sustainable strategy to manage this more

CRC50091: Ensuring Effective Phosphine ApplicationMr Greg Hopkins

The aim of this project is to experimentally determine and mathematically model the movement of phosphine fumigant in large grain storages and its associated efficacy. This information will then more

CRC50092: Alternatives to phosphine reviewDr Patrick Collins

This review will provide the CRCNPB with a basis for strategic investment into the technologies that have the potential to be developed into effective insect control systems compatible with grain more

CRC50098: Fumigation Protocols for Flat Grain BeetlesDr Manoj Nayak

Flat grain beetle (FGB) is a major emergency plant pest (EPP) of stored grain in Australia. Populations of FGB have recently developed high level resistance to phosphine (the only viable fumigant more

CRC50116: Resistance MonitoringDr Manoj Nayak

A range of naturalised harmful plant storage pests including beetles, psocids, moths and mites habitually threaten the food safety, market access, trade and the overall profitability and more

CRC50147: Low oxygen technology for alternative to phosphineDr YongLin Ren

This project aimed to develop cost-effective, readily adoptable alternatives to a phosphine fumigant that will control resistant insects and comply with industry and market more

CRC50150: Targeting mechanisms of phosphine resistance in stored grain pestsDr David Schlipalius


CRC50151: Resistance Monitoring (Phase 2)Dr Manoj Nayak

A range of naturalised harmful plant storage pests including beetles, psocids, moths and mites habitually threaten the food safety, market access, trade and the overall profitability and more

CRC50177: Australian Grain Insect Resistance Database - data miningDr Patrick Collins

The aim of this pilot project was to develop a statistical methodology for analysing the database so that insights into resistance development might be obtained.

CRC50188: Dispersal and resource use by the lesser grain borer (Rhyzopertha dominica) in southern New South Wales

This project looked at two aspects of the biology of lesser grain borer, dispersal ability and potential use of food sources other than stored grains.

Research outcomes:
