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.

Scientists from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in Niger say that 99 percent of the media and research coverage on the fall armyworm focuses on the invasive pest’s deadly threat to maize.
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.
A major new report published by CABI has today revealed that losses due to fall armyworm are lower than projected in 2017 and the pest is still primarily focussed on maize rather than any other potential host crops. Better monitoring, swift responses by governments and farmers and an increase of natural enemies attacking the pest all help in mitigating the devastating crop losses it can cause.
Invasive alien weed species have been a global environmental and human health issue for decades. In 1969, CABI organised the first International Symposium on Biological Control of Weeds (ISBCW) in Delémont, Switzerland. Weed biocontrol research was then in its early stages and 20 scientists attended.
