New fungus to help Australian farmers fight fast-spreading weed by CSIRO


Farmers now have a new biocontrol tool to help fight one of Australia's most challenging agricultural weeds, flaxleaf fleabane, which causes grain crop revenue losses of more than $43 million each year. Researchers from Australia's national science agency, CSIRO, are piloting the release of a fungus from Columbia to help farmers tackle the weed.

Flaxleaf fleabane (Conyza bonariensis) is a fast-spreading weed from South America that damages cropping and grazing areas across Australia and impacts the livelihoods of many farmers. CSIRO weed ecologist, Dr. Ben Gooden, said flaxleaf fleabane is one of the most difficult-to-control weeds in grain cropping systems, and is estimated to affect nearly three million hectares of land in Australia.
