This project aims to develop an effective knowledge exchange strategy for the grains industry to improve its phosphine insect resistance management outcomes through identification of the methods in which information is delivered and exchanged through the grains supply chain.

What is the biosecurity problem?

Phosphine is currently the only chemical for management of insects in stored grain with the combined attributes of being cheap, effective for most commodities, compatible with grain handling logistics and accepted by domestic and international markets as residue-free.

As a result, phosphine is central to pest management in the Australian grains industry and its continued effectiveness is essential for the sustainability of long term storage of, and market access for, Australian grain. In the past fifteen years, insect resistance to phosphine has increased in both frequency and strength such that it now threatens effective control thereby posing a significant biosecurity threat.

A key issue with the development of insect resistance to phosphine is incorrect application of the chemical through lack of understanding of, or lack of incentive for, its correct use. Identification of mechanisms that deliver information in a way that results in changes in the behaviour of stakeholders in the grains supply chain is therefore critical in limiting the development of insect resistance to phosphine. To achieve this, evaluation and provision of methods of information exchange is needed. This project will evaluate and develop knowledge exchange networks to limit development of phosphine resistance and ensure rapid adoption of new practices.

The main outputs of the project are to:

• identify and evaluate the networks that exist within the grains industry for the delivery and exchange of information
  
• assist, establish and maintain mechanisms to deliver information on correct use of phosphine for control of insects of stored grain, and
  
• identify economic factors and market drivers that influence phosphine resistance management practices.
  

Who will the end users of this research?

The end users of the research will be individuals or businesses within the grains industry who deliver information on limiting the development of phosphine resistance. Growers and grains bulk handlers will benefit from this research through improved clarity and consistency of information on the management of stored grain.
