An introduction to the 'demon plant' parthenium weed.

Abstract Research on parthenium weed (Parthenium hysterophorus) is in progress in many countries, including Australia, India, South Africa, Ethiopia, Pakistan, Bangladesh, China, Sri Lanka and Nepal. This book, with contributions from expert researchers with extensive involvement in parthenium weed research from these countries, has collected and synthesized existing knowledge on parthenium weed in 16 chapters covering aspects of: (i) biology; (ii) ecology; (iii) genetics; (iv) introduction histories; (v) geographical distribution; (vi) the impact on agriculture, natural forests and the environment of protected areas; (vii) allelopathy; (viii) impacts on human and animal health; (ix) potential uses; and (x) management strategies, including chemical, cultural and biological control methods. The book also provides current distribution records/status of the weed, along with future risks of spread based on climate change. There are dedicated chapters on the current status of parthenium weed problems in Australia and the Pacific, Southern Asia, East and South-east Asia, North Africa and the Middle East, and southern Africa. All chapters have relevant photos and figures included to make the reading interesting. This is the first book on parthenium weed under the CABI invasive species series. The book will be of immense value to all countries with a parthenium problem, which will benefit by sharing knowledge and experience.
