Parthenium hysterophorus L., commonly known as carrot weed or congress grass in India has been considered as one of the worst weeds responsible for causing health problems in men and animals besides loss to crop productivity and plant biodiversity.  The weed has infested about 35 million hectares of land in India since its first notice in 1955. Now it has become one of the main weeds in almost all types of agricultural lands besides infesting wasteland, community land, road and railway track sides and forests. In an attempt of biological control, search for suitable bioagent began in 1980s in India through systematic surveys. The work on biological control through competitive plants was started with the search of Cassia sericea from south India which lead to more attempts to manage Parthenium by competitive plant species. Casia tora and C. sericea have been recommended most suitable plant species for management of Parthenium in wasteland, on the raod side and community land. Likewise, in spite of hundreds of reports of pathogens causing disease on Parthenium, none of them has qualified as successful bioagent. So far, attempts of developing effective mycoherbicides have not yielded any success. Not even a single indigenous insect species has proved successful in spite of occurrence and infestation by many species. Under classical bilogical control of Parthenium in India, three insect species were imported in 1983 from Mexico, out of which only host-specific leaf-feeding beetle Zygogramma bicolorata Pallister (Coleoptera: Chrysomelidae) was proved successful. Z. bicolorata has established in many parts of the country and has been found responsible to decrease the Parthenium densities in different parts of India. This paper gives details of current status of biological control of Parthenium and future strategies in India.
