Kordyana brasiliensis for the biological control of Tradescantia fluminensis

We conducted a risk analysis for the proposed release of the fungus Kordyana brasiliensis into Australia. The purpose of this release is to control the weed ‘Wandering Trad’ (Tradescantia fluminensis).

The use of exotic biological control agents to control invertebrate pests, weeds and other organisms has been common in Australia for many years. Releasing pathogenic, herbivorous, predatory or parasitic organisms into the Australian environment can have potential “off-target” risks. This means risk to other plants or invertebrate animals not targeted by the biological control agent.

We began this risk analysis in response to an application to release Kordyana brasiliensis to control Wandering Trad. The application was submitted by the Commonwealth Scientific and Industrial Research Organisation (CSIRO).

We have now released a final report, which:

  • estimates off-target risks and potential consequences of the release
  • evaluates the risk to be Negligible, which meets Australia’s appropriate level of protection (ALOP)
  • recommends the release of the biological control agent Kordyana brasiliensis.
