Biological control of serrated tussock

Biological control is the long-term management option that uses the natural enemies of a weed, such as insects and fungi. 

Biological control programs take many years to become established and will never eradicate the weed.  Instead they reduce the weed's competitiveness and limit its impact.

Serrated tussock was declared a target for biological control in 1999.  Three potential agents have been identified and tested to date.  None of these pathogens look like suitable candidates for biological control of serrated tussock in Australia.

If you observe serrated tussock plants dieing or sick for no apparent reason, it is important to report this to your local Weeds Officer.
