About the guide

Praxelis is on the Alert List for Environmental Weeds, a list of 28 non-native plants that threaten biodiversity and cause other environmental damage. Although only in the early stages of establishment, these weeds have the potential to seriously degrade Australia's ecosystems.

Praxelis was first recorded in Tully and Innisfail, Queensland, in 1993 but was probably present there for about 20 years before being positively identified. It is spreading extremely quickly and effectively throughout northern and eastern Queensland - an isolated infestation recently found in Gympie is some 1200 km by road south of the nearest infestation in Townsville.

An invader of both disturbed and relatively undisturbed ecosystems, praxelis could threaten, and significantly increase the costs of managing, such crops as bananas, other fruits and sugar cane. It could infest pastoral grasslands and conservation areas, particularly open eucalypt woodlands. Praxelis is easily mistaken for two species of Ageratum, less serious weeds found in similar regions.

There is some evidence that it may be poisonous to stock and humans if ingested.
