Invasive plant species have the potential to damage crops, industries, environment and public health, hence scientists, academicians, leaders of industry and land managers are realizing that invasive species are serious environmental threats for the 21st century. Parthenium weed is an annual herb in the family Asteraceae which is native to northern Mexico and southern USA. It is spreading across the length and breadth of our country. It gets easily established in almost all the places such as wasteland, roadsides, forests, railway tracks, crop fields, etc. Its high germination ability throughout the year, an enormous seed bank, rapid spread, colonization and extreme adaptability in a wide range of habitats is responsible for its wide spread occurrence. Parthenium hysterophorus L. was reported to be one of the seven most dangerous weeds of the world. It has achieved a major weed status in India and Australia within a relatively short period due to its fast multiplication, rapid growth and its ability to compete with other native flora. There are many ways like mechanical, chemical, cultural and biological to control it, but it cannot be controlled by using a single approach. Integrated approach should be the better way to manage this noxious weed. The aim of this review is to provide general information about the physiology, distribution, ill effects and management of Parthenium.
