International acceptance of Australian solanaceous and cucurbit seed tests

Final Report Summary

June 2017

This project has established seed testing protocols that can be used as an international standard for detection of viroids and cucumber green mottle mosaic virus (CGMMV) in seed, and to reduce the risks presented by contaminated traded seed. The protocols will meet the stringent requirements of sensitivity required by Australian quarantine at the border while minimising cost to industry.

It is anticipated that the Australian protocols developed in this project for detection of Pospiviroid species and CGMMV in seed will be fully implemented by Australian regulatory authorities, improving biosecurity measures on vegetable seeds. It is further anticipated that the scientific outcomes of the project and symposium will result in internationally harmonized testing procedures for Pospiviroid species and CGMMV in internationally traded solanaceous and cucurbit seed.

The research recommended that Australian regulatory authorities:

  • Adopt updated molecular protocols that were developed and evaluated in this project to improve detection of Pospiviroid species in solanaceous seed.

  • Adopt molecular protocols that were developed and evaluated in this project to increase the possibility of detection of CGMMV in cucurbit seed.
