Parthenium hysterophorus is a highly destructive weed which has invaded and is widespread in around 48 countries in Africa, Asia, and the South Pacific. In Pakistan the weed is spreading rapidly westwards and southwards across both rural and urban landscapes, affecting native ecology and harming agriculture.
2018 has been a bumper year for the CABI Invasives blog, with 4 times more posts than 2017 and over twice the number of views (over 20,000!). With so many articles published this year, we have compiled a list of the top 20 most read to round off 2018.
Invasive species pose a serious threat to food security, biodiversity, water resources, human and animal health, and economic development. It is widely acknowledged that integrated control is the most effective strategy in managing invasive plants where it involves the use of herbicides, manual or mechanical control, and biological control agents in an integrated way. Last month, a short course on invasion biology and classical biological control of weeds was delivered at CABI in Pakistan.
In Pakistan, the highly invasive weed Parthenium hysterophorusis not only a problem for rural areas, in fact it is of equal concern for urban residents as well. Known locally as ‘Gajar Booti’, Parthenium is a major pest of both cropped and non-cropped areas of Pakistan, causing severe economic, environmental, and health-related problems.
Latest book in the CABI Invasive Series: Parthenium Weed
Parthenium weed (Parthenium hysterophorus) is considered one of the worst weeds in the world. It has invaded and is widespread in about 48 countries in Africa, Asia and the South Pacific, and has the potential to spread to new countries in Africa, Asia and parts of Europe. In the countries it has invaded, it has devastating effects on the livelihoods of millions of people causing significant economic, health and environmental loss. In order to effectively manage parthenium weed and mitigate the impacts it has, one needs a good understanding of the biology and ecology of the weed as well as effective management strategies already utilised. As the editors of CABI’s new book on Parthenium so candidly put, ‘know your enemy’ is the first step in effective management.
In Pakistan, it has been reported that this weed is present almost everywhere, but the dilemma is that the general public have little to no knowledge about its harmful impacts. Keeping in view these facts, CABI in Pakistan under the Action on Invasives programme, recently launched an awareness drive in the rural areas of the Sheikhupura district to spread information on the negative impacts of this alien weed among more remote communities.
“Usually I’m looking up at the stars but with this project, I’m back down to earth” quips Dr Rene Breton, Director of Research at the School of Physics and Astronomy at the University of Manchester. By combining the skills of a geographer, ecologist, social scientist, entomologist, astrophysicist, biologist, and electrical engineer, the joint CABI and University of Manchester team aim to capitalise on the unique skills from each subject to tackle the highly invasive weed Parthenium in Pakistan using remote sensing.
