3037: Investigation of sources of insecticide residues in stored grains and oilseeds

Final Summary

This project generated data to demonstrate levels, sources and distributions of insecticide residues in stored coarse grains and oilseeds to:

  • guide industry in development of chemical strategy
  • management of phosphine resistance, and
  • management of chemical residues.

The Australian grain industry relies heavily on chemicals for grain treatment. More than 85 per cent of grain is treated with phosphine. However, increasing resistance of insects has broadly occurred. Other registered grain fumigants that are alternatives to manage phosphine resistance are available however it is important to identify potential residues associated with their use.

Impact

Economic: The economic viability of Australia's plant industries (with farm gate and export income values of over $18 billion and $12 billion, respectively) could be directly threatened. The ongoing supply of agricultural products to the domestic market, and international commerce associated with the entire supply chain are also at risk.

Environmental: This project will significantly protect the ozone layer by a reduction of methyl bromide emissions and/or replacement of methyl bromide as the preferred fumigant for quarantine treatment

Social: Assist farmers to remain in sustainable agri-business. Ensure food costs remain reasonably priced for the wider community. Encourage employment in the farm sector. Protection of the ozone layer resulting in reduced associated health concerns (e.g. skin cancers).
