Action on Invasives short course on classical weed biological control

DSC_0240
Zygogramma bicolorata, often referred to as ‘The Parthenium Beetle’ feeds on the leaves of Parthenium and is already being used as a biocontrol in a number of countries

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.

Parthenium awareness campaign reaches urban population in Islamabad

Parthenium in Pakistan

In Pakistan, the highly invasive weed Parthenium hysterophorus is 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.

In the fight against Parthenium, make sure to “know your enemy”

Latest book in the CABI Invasive Series: Parthenium Weed

Parthenium Weed.indd

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.

Dr Umair Safdar talks through the documentary shown to farmers

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.
