Siam Weed (Chromolaena odorata)
If you see this weed please contact the Weeds Management Branch immediately on 899 94567
Siam weed is on the Alert List for Environmental Weeds, a list of 28 non-native plants that threaten biodiversity and cause other environmental damage. Siam weed has the potential to seriously degrade Australia’s ecosystems.
Siam weed is recognised as one of the world’s worst tropical weeds. It has an extremely fast growth rate (up to 20 mm per day) and prolific seed production. In the tropics of Africa and Asia it is a major pest of crops such as coconuts, rubber, tobacco and sugar cane. Some agricultural areas in South-East Asia have been abandoned because Siam weed has taken over pastures and crops. It is also toxic to stock. For more information go to the Weeds Australia web site.
Siam weed is declared a Class C (not to be introduced to the Northern Territory) weed in accordance with the NT Weeds Management Act.
