This volume has 11 Chapters, divided in three Sections viz., Entomology, Nematology and Weeds. It provides complete information about the various techniques used for Allelopathy Research in the field of Entomology, Nematology and Weeds. It is written in a simple and lucid language. It will be very useful to undergraduate and Post graduate students and Faculty for used in Class room and Laboratory experiments and research. We are thankful to Prof. G. S. Dhaliwal, Department of Entomology, Punjab Agricultural University, Ludhiana and Prof. V. Mojumder, Division of Nematology, Indian Agricultural Research Institute, New Delhi for Peer Review of Entomology and Nematology Manuscripts.

This book provides the reader relevant information about actual knowledge about the process of allelopathy, covering all aspects from the molecular to the ecological level. Special relevance is given to the physiological and ecophysiological aspects of allelopathy. Several ecosystems are studied and methodological considerations are taken into account in several different chapters. The book has been written to be useful both for Ph.D. students and for senior researchers, so the chapters include all necessary information to be read by beginners, but they also include a lot of useful information and discussion for the initiated.

Prosopis (Prosopis juliflora) is a xerophyte which, in its native habitats has been a desert plant. As long as it was confined to that habitat, P. juliflora was a great resource, improving the region's micrometeorology, binding its sandy soil, and providing shelter, fuel, feed, food, medicines, and cosmetics to the people of such regions. In particular, for the economically weaker inhabitants, P.juliflora was a lifeline.But when P. juliflora was indiscriminately introduced in other regions of the world in a hope to derive similar benefits from it, things began to go awry. Indeed, among the invasive species of plants which are spreading at an alarming rate in the tropical and sub-tropical regions of the world, P.juliflora is arguably the most hardy and resilient. It is growing so explosively that it even enters roads and homes, driving humans out of their dwellings. The resulting damage to biodiversity is enormous. This book highlights the dual role played so far by P. juliflora and itemizes the facets that make it a blessing in some contexts and a bane in other contexts.Authored by leading experts in the field, Prosopis juliflora: Attributes, Impact, Utilization is the first title of its kind to comprehensively discuss this hardy plant species. It will be an essential read for students, researchers and governmental agencies interested in plant biology, forestry, plant ecology, invasive plant species and environmental science. - Summarizes all the key information available on P. juliflora, from its origin and systematics to its future prospects - Discusses colonization, utilization and eradication - Authored by leading experts in the field with over 40 years of experience

The principal goal of allelopathy is to foster sustainable agriculture, forestry, and environment. The objective is to minimize the industrial chemicals and to maximize the use of natural resources locally available while improving crop productivity, forestry and the environment. The technological advances made in allelopathy research in recent years have been created, analyzed, and developed by scientific establishments throughout the world. They present exciting and intellectually challenging problems which are solvable using modern techniques. These modern and advanced techniques as described in the chapters presented in this volume are representative of the exciting research and development approaches today.

With a claim to be the first work to document in detail the history of allelopathy, Willis’s text provides an account of the concept of allelopathy as it has occurred through the course of botanical literature from the earliest recorded writings to the modern era. A great deal of information is presented here in a consolidated and accessible form for the first time. The book offers a unique insight into the historical factors which have influenced the popularity of allelopathy.

Allelopathic studies may be defined in various aspects; weed against weed/crop and vice versa. This book focuses on the ways to utilize the allelopathic potential of weeds or crops for controlling weeds in the agroecosystems. Vigorous use of herbicides is poisoning our environment at an alarming rate; allelopathy can be employed as a useful alternative to control weeds naturally under field conditions. The book contains chapters on the history of allelopathy; allelopathic potential of several important crops (rice, wheat, sorghum, maize, mustard, sunflower) and weeds (members of Solanaceae, Convolvulaceae, Asteraceae, Verbenaceae). Moreover, it highlights how the allelopathic potential of these weeds and crops can be employed effectively to suppress weeds under field conditions. The book also discusses topics on the role of allelochemicals in agroecosystems; impact on local flora; biotic stress induced by allelochemicals; mechanism of action of allelochemicals and future prospective of allelopathy. Prepared with basic concepts and importance of allelopathy, this book is intended for the agricultural community, botanists, students and researchers.
