Capsicums and chillies grown in areas with Queensland fruit fly (Qfly) but destined for markets free of this pest must meet quarantine protocols. Many growers previously met Interstate and International requirements by flood-spraying postharvest with either dimethoate or fenthion insecticide. Both treatments have now been withdrawn for use on capsicums, with only fenthion currently permitted for chillies. This project has developed a cold disinfestation treatment for capsicums and chillies. To reduce sensitivity to cold, the fruit was showered with 55oC water for 60 seconds before cold treatment.

This project has been funded by Hort Innovation, using the research and development levies listed below and contributions from the Australian Government. Hort Innovation is the grower-owned, not-for-profit research and development corporation for Australian horticulture.
