Brazil: in regions without harsh winters, Parthenium hysterophorus is present and flowers almost all year round.
China: Parthenium hysterophorus flowers from April to August.
Mayotte: Parthenium hysterophorus flowers and fruits all the yezr round.
New Caledonia: Germination of Parthenium hysterophorus takes place throughout the year if moisture and heat conditions allows it, usually early in the rainy season. The plant first develops in rosette and starts flowering 1 to 2 weeks after and during a long period of more than 6 months.
West Indies: Parthenium hysterophorus flowers almost all year round.

Toxicity
In India, Parthenium hysterophorus is considered toxic to livestock, ingested by hungry animals, it makes the meat not consumable. Cows can also be affected and pass the toxic principle into their milk. For the man prolonged contact causes allergic reactions (dermatitis, asthma). The entire plant contains allelopathic components (sesquiterpenes) limiting germination of other species and seedling growth.

Origin
Parthenium hysterophorus is native to Central America and the Caribbean and South America.
Worldwide distribution
The species is widespread in all tropical and subtropical regions. USA, Caribbean, Eastern and Southern Africa, India, Asia, Australia and the Pacific and Indian Ocean islands. It is absent from Central and West Africa.

Global control
Chemical : Glyphosate at 1.0% under non cropped area.
A number of control measures, such as cultural, physical, chemical and biological techniques, have been adopted in combination to manage P. hysterophorus in other invaded countries (Adkins & Shabbir, 2014). Biological management has included the use of suppressive plants (i.e. the planting of beneficial plants that can suppress the growth of P. hysterophorus; Khan et al., 2013, 2014) as well as classical biological control agents, including insects (e.g. Zigogramma bicolorata, Epiblema strenuana Walker) and pathogens (e.g. Puccinia abrupta var. partheniicola (Jackson) Parmelee).
Local control
Australia: 9 insects and 2 pathogens selected and introduced into Australia between 1985 and 2004. All established, 5 biological control agents dispersed and showing effective action. Among the insects Zygogramma bicolorata (Chrysomelidae) whose larvae and adults cause defoliation (very effective), Smicronyx lutulentus (Curculionidae) whose larvae consume fruits and adults consume leaves (very effective), Epiblema strenuana (Tortricidae) whose larvae cause stem scab, Listronotus setosipennis (Curculionidae) stem borer, Carmenta cf. ithacea (Sesiidae) whose larvae consume the roots, Conotrachelus albocinereus (Curculionidae) causes stem galls. Among the pathogens are the winter rust Puccinia abrupta var. partheniicola, which is more suitable for cold regions, and the summer rust Puccinia xanthii var. parthenii-hysterophorae. The actions of the rusts are highly variable.
Ethiopia: Introduction and release of Zygogramma bicolorata (Chrysomelidae) in 2019 and Listronotus setosipennis (Curculionidae).
India: Introduction and release of Zygogramma bicolorata in 1984. Good establishment of the chrysomelid.
Madagascar: The manual control Parthenium hysterophorus can be done by pulling. Chemically, it is controlled with 2,4-D herbicide.
Nepal : As no single measure has been effective in managing this weed, an integrated weed management approach has been recommended (Dhileepan, 2009; Adkins & Shabbir, 2014). Even though P. hysterophorus is already widespread in Nepal, with negative impacts upon biodiversity, agricultural production and health, to date no systematic effort has been made to manage this weed. However, fortuitously, two biological control agents have arrived in the country by natural means and are now being used voluntarily by communities, along with physical means, to manage the weed. Control of P. hysterophorus from the current efforts of the communities and the currently available biological control agents is unlikely to be adequate. Release of additional biological control agents, after careful quarantine screening to ensure suitability for release in Nepal, is recommended to increase the efficacy of control measures. Various biological control agents have arrived naturally in Nepal, probably from India (Zygogramma bicolorata and Puccinia abrupta var. partheniicola).
New Caledonia: It is necessary to control the beginning of infestations isolated by tearing (with thick gloves because of the risks of allergy). For larger invasions, the use of chemical control is necessary in some situations with spray treatment in the rainy season to allow grazing to resume (2,4-D, 2,4-D + picloram, dicamba). Targeted treatment of regrowth should also be considered. Biological control is currently being developed in Queensland with various insects (encouraging result with the butterfly Epiblema strenuana). It is important for this species to keep livestock from infested areas in quarantine plots before re-entering the rotation.
Pakistan: Biological control agents have arrived naturally in Pakistan (Zygogramma bicolorata and Puccinia abrupta var. partheniicola). One agent has been introduced Listronotus setosipennis.
South Africa: In 1995 discovery of Puccinia abrupta var. partheniicola, 2010 introduction of Puccinia xanthii (being disseminated), 2013 Listronotus setosipennis (Curculionidae) attacks the stem, low dispersal. 2013 introduction of Zygogramma bicolorata (Chrysomelidae) defoliator, limited establishment. 2015 Smicronyx lutulentus (Curculionidae) seed-eating larvae, under establishment.
