CSIRO releases Brazilian leaf smut fungus to target and kill invasive weed

Science agency says scourge of wandering trad could be slowed by fungus, which they have called its 'natural pathogen'

Australia's national science agency will release a Brazilian leaf smut fungus to target and kill an invasive weed that covers large parts of the continent's east coast.

Researchers from the CSIRO say the scourge of wandering trad could be slowed by the introduction of the Kordyana brasiliensis fungus, which they have called its "natural pathogen".
