We have released the draft risk analysis report for the proposed release of the leaf rust pathogen, Puccinia lantanae for the biological control of the weed lantana (Lantana camara).
The draft report proposes that the release of the biological control agent should be permitted, subject to standard import and release conditions associated with exotic biological control agents.
The draft report is open for 30-calendar days public consultation, closing on 6 March 2026.
We invite you to have your say on the draft report. We will consider all stakeholder comments received during the consultation period in preparing a final report.
The draft report proposes that the biological control agent, Puccinia lantanae, is permitted for release to control the weed lantana (Lantana camara). The risk is estimated to be Negligible, which achieves Australia’s appropriate level of protection (ALOP).
The applicant, the Queensland Department of Primary Industries (QDPI), provided a submission in support of their application to release the biological control agent. The submission detailed the results of host-specificity testing, together with other relevant information. This submission is included as an attachment to the draft report.
The standard consultation period for biological control risk analyses is 30 days, which differs from the standard 60 days for other risk analyses. This is because the department has consulted extensively with all state and territory governments, the Department of Climate Change, Energy, the Environment and Water (DCCEEW) and the CSIRO and there was no opposition to the release of Puccinia lantanae as a biological control agent. This approach is consistent with the Revised guidelines for the introduction of exotic biological control agents for the control of weeds and plant pests.
The draft report and information about the risk analysis process are available online.
