3150: An integrated approach to manage pests and resistance to phosphine in stored grain (Phase 2)



Consultation with industry and direction from PBCRC Science Committee identified seven issues that are critical to achieving effective delivery of benefits to the Australian grain industry through this project. These issues include:

1 & 2. Finalise work on sulfuryl fluoride (SF) by delivering cost-effective fumigation protocols in tabulated values both for grain bunkers and vertical silos.

3. Finalise field work and deliver phosphine fumigation protocols to control strongly resistant rusty grain beetles (Cryptolestes ferrugineus) in bulk storages to improve labelling for cylindered phosphine.

4. Complete fumigation ‘time to reinfestation’ research (phosphine and SF) to provide industry with a new decision tool to gain resistance profile of pests and drive fumigation efficiencies.

5. Work with industry to address gaps in current labelling for use of aluminium phosphide in large (>150 t) farm silos that has arisen through de-regulation and the subsequent increase in on-farm use of large silos.

6. Complete work with industry on efficacy and integration of various eradication interventions for control of resistant pests (e.g. extra hygiene, structural treatments, break fumigant such as SF).

7. Integrate recommendations into the National Resistance Management Strategy.


Economic: Developing SF as an alternative and delivery of the pest management tools will ensure that both growers and bulk handling companies meet their market requirements. We expect a much broader impact on industry through adoption of 'ready to use' protocols for phosphine and SF within 5 years. 

Environmental: Resistance management will ensure that fumigants are used correctly and minimally which will lead to insignificant environmental impacts and enhance safety considerations for workers. 

Social: The project outputs will help growers and bulk handling companies maintain their profitability by meeting market requirements. This will help to sustain regional and rural economies.
