CSIRO to deploy smut fungus


The CSIRO has announced it will be deploying a leaf smut fungus to combat the spread of the wandering trad invasive weed, which is rapidly spreading throughout the east of the country.

CSIRO’s senior research scientist, Dr Louis Morin, said that weeds like trad have a significant economic, environmental and social impact in Australia.

“Weeds are one of the biggest threats to Australia’s unique environment – in many areas across Australia they are damaging native vegetation, which threatens whole ecosystems including native wildlife,” Dr Morin said.

“Last year Australia spent almost $30 million protecting the natural environment from weeds. In the agriculture sector, weeds cost the industry more than $4.8 billion per year.”

CSIRO field biologist Dr Ben Gooden, who is coordinating the rollout of the biocontrol program across Australia, said highly targeted and tested biocontrol agents like the fungus were a more environmentally sustainable option than other available tools.

“Scientifically tested biocontrol agents like this fungus provide a longer term, environmentally sustainable way of controlling weeds like wandering trad, without harming Australian plants or animals,” Dr Gooden said.

“Currently, the only tools available to the community and local councils against the weed are hand-pulling and chemical herbicides, which only bring short-term control and have the unintended consequence of killing native plants and disrupting complex rainforest ecosystems.”
