other print media to increase public awareness. It is the responsibility of the local
Shires and Council to eradicate, using herbicides, any parthenium infestations in
urban and residential areas. Though manual control, including hand pulling appear
the cheapest option, in view of the health risk, a chemical control in conjunction
with a program to competitively displace parthenium with a suite of beneficial
plants appears suitable for majority of countries where parthenium is a major prob-
lem in urban areas (Table 12.5). However, a legislative framework to contain or
eradiate parthenium within the urban areas either at local or state government level
is lacking in many countries.
12.6 Conclusion
The ability of parthenium to grow in a wide range of areas (e.g. wastelands, dis-
turbed lands, degraded pastures, crops, forests, along railway tracks and roadsides,
and along streams and rivers), across a wide range of habitats (e.g. hot, arid, semi-
arid, humid high-altitude areas), its persistent seed bank and its allelopathic poten-
tial all make the management of this weed more difficult. No single management
option would be adequate to control this weed across all habitats, and there is a
need to integrate various management options (e.g. grazing management, competi-
tive displacement, cultural practices) with classical biological control as a core
management option.
