CRC50147: Low oxygen technology for alternative to phosphine

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 standards.

Research outcomes:

  • Establish rate of desorption of air from grain under nitrogen.
  • New knowledge of insect response (toxicity, behavioural) to low O2/high N2 concentrations and its relationship to phosphine resistance.
  • New knowledge of the effects on grain quality of storage under nitrogen.
  • New nitrogen application method.

Research implications:

This research has led to development of cost-effective, readily adoptable phosphine alternatives that will control resistant insects and comply with industry and market standards which significantly contribute to further enhance Australian grain industry reputation in both domestic and international market.
