Invasive weeds have threatened the integrity of ecosystems throughout the world. They affect not only the species diversity of native areas but also their biological integrity. In India, a number of invasive exotic weeds have been reported but some viz. Parthenium hysterophorus, Lantana camara and Ageratum conyzoides, especially those from tropical America are troublesome and have caused adverse ecological, economic and social impact. These weeds can be seen growing in different landscapes but… 

Biology, ecology and spread of the invasive weed Parthenium hysterophorus in India.

Parthenium hysterophorus L. (family Asteraceae, and hereafter referred to as Parthenium) is an obnoxious invasive weed from tropical America that has spread to various tropical and subtropical parts

Parthenium weed invasion and biodiversity loss in Ethiopia : A literature review

Parthenium weed (Parthenium hysterophorus L.) is an invasive alien species whose mode of introduction is uncertain, although it was first recorded in Ethiopia in 1968. Since then it has been

Invasive Alien Weed Species Distribution, Impacts on Agriculture, Challenge and Reaction in Ethiopia: A Review

Invasive Alien Species are of a great concern in Ethiopia, posing particular problems on agricultural lands, range lands, biodiversity of the country, national parks, water ways, rivers, power dams,

Invasion status and impacts of parthenium weed (Parthenium hysterophorus) in West-Central region of Bhutan

Parthenium weed (Parthenium hysterophorus L.) is an invasive alien plant species that is spreading rapidly all over the world. With globalization and climate change, it will continue to spread,

Parthenium hysterophorus and Bidens pilosa, two new records to the invasive weed flora of the United Arab Emirates.

The presence of these cosmopolitans under the hyperarid climates of UAE indicates their great tolerances to the harsh climatic conditions, and both species are considered as good colonizers; they have explosive reproductive potential and ability to thrive in diverse habitats.

Threats and Management Options of Parthenium (Parthenium hysterophorus l.) in Ethiopia

Sustainable long term management strategies should include prevention, use of replacement competitive plants in newly infested and insect bio-agents in severely infested areas, integrated use of herbicides as well as rehabilitation with useful plant species has to be developed.

Infestation Of Weed Vegetation Parthenium hysterophorus L. In Tehri Garhwal Himalaya, Uttarakhand, India

Parthenium hysterophorus L. is a weed of global significance causing severe economic, environmental, agricultural, biodiversity, livestock, and human health problems. It is a highly noxious, invasive

Allelopathic effect of Parthenium hysterophorus L. on growth and productivity of Zea mays L. and its phytochemical screening.

Parthenium is an annual herbaceous prolific weed belonging to Asteraceae family and has been accidentally introduced in India along with food grain PL-480 and not only competes with desirable crop and pasture species but also reported as a health.

Biology, ecology and management of the invasive parthenium weed (Parthenium hysterophorus L.).

An integrated management approach is proposed here for the effective management of parthenium weed on a sustainable basis.



A century of classical biological control of Lantana camara: can pathogens make a significant difference?

Preliminary work has started on a Peruvian isolate of the rust, and initial evidence indicates that it is able to infect a wider number of weedy cultivars and it is significantly more damaging to the target plant, causing cankering and stem die-back, than Prospodium.

Impact of Invasive Plants on the Structure and Composition of Natural Vegetation of Northwestern Indian Himalayas1

A study conducted to assess the changes in the structural composition and dynamics of vegetation shows that density and diversity of native flora were adversely affected because of invasion by these three exotics.

Biological control of Parthenium hysterophorus L. (Asteraceae) by Cassia uniflora Mill (Leguminosae), in Bangalore, India

Cassia uniflora a leguminous undershrub of some economic value, is found to suppress the growth of parthenium, an obnoxious Asteraceous weed, which has spread over millions of hectares of land in India after its inadvertent introduction in the 1950s.

Allelopathic plants. 10. Lantana camara L.

Lantana camara L. is an introduced weed in the tropics and subtropies and infests 14 crops in 47 countries and has medicinal, herbicidal and fungistatic activity.

Exhibition of allelopathy by Parthenium hysterophorus L. in Agroecosystems

The bio-efficacy studies of the soil chemicals conducted on a representative plant Phaseolus aureus, points to its inhibitory nature and the chemicals accumulated in the soil infested with P. hysterophorus, qualify to be called as allelochemicals.

Allelopathic Potential and Chemical Constituents of Volatiles from Ageratum conyzoides Under Stress

Volatiles from A. conyzoides plants infected with E. cichoracearum or exposed to A. gossypii feeding inhibited or killed fungi and insects, and phytoinhibitory effects decreased under fungal infection and aphid feeding.

Allelopathy and exotic plant invasion

It is argued that non-resource mechanisms should be returned to the discussion table as a potential mechanism for explaining the remarkable success of some invasive species.
