The Australian Department of Agriculture, Water and the Environment conducted a risk analysis for the release of the rust fungus Puccinia spegazzinii for the biological control of the weed Mikania micrantha.
The final report recommends that the release of P. spegazzinii should be permitted, subject to standard quarantine conditions associated with the import and release of biological control agents, and determined the overall risk associated with the release of P. spegazzinii to be Negligible.
