Abstract
This book has been a collective effort by 26 members of the International Parthenium Weed Network, which is an International network of expert volunteers devoted to creating awareness about the parthenium weed (Parthenium hysterophorus) threat, and to sharing information on how to reduce its adverse impacts upon agro-ecosystems, the environment and human health. The book builds on a fundamental understanding of invasive plant biology and weed science that can be acquired from the many good texts available. Its broad aim is to emphasize the practical relevance of understanding biology and ecology to enable effective and sustainable management. The book has a conspicuously world focus, drawing on examples from 48 countries invaded by this phenomenal weed. It contains 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. This book will be a comprehensive reference book for researchers, students, professionals involved in weed management, government officials and policy makers and anyone interested in parthenium weed. As the research needs and knowledge gaps vary widely across different countries, the book has also identified these gaps, and provides direction for future research for various countries.
