Focusing on those poisonous plant species with a broad geographic distribution and the greatest economic effect, the contributor to this interdisciplinary volume examine the environmental factors that promote or encourage poisonous plant growth and spread, plant population cycles, the conditions under which poisoning occurs, toxins responsible for poisoning and their effects on livestock, and the management responses to reduce losses.The general economic impact is also examined, looking at Frequency and economic aspect of loss from outright death to reduced weaning weight and reproductive efficiency- and forage losses within the context of annual, sporadic or catastrophic losses as well as the costs of the prevention are examined within an agricultural economic aspects of poisons plant control and management. This book is of interest not only to range scientist but also to botanists, ecologists, animal scientists, and behavior lists, and agricultural economists. It will serve as both a source book and a useful methodological guide. 

This book gives a comprehensive account of major economically important diseases of fruits and plantation crops of tropical and subtropical regions. Each chapter includes distribution, symptomatology with colour photographs, casual agent, epidemiology, disease cycle, various management strategies includes cultural, host plant resistance, chemical and biological & biotech approaches. The book also gives a detailed calendar of operations in for disease management in each of these crops. The detailed bibliography is also provided at the end. The book serves an important guide for teachers, researchers, extension workers and farming community at large.

The Book is based on research work delving into the history of forest management in the last 150 years, critically examining the changes in policy, changes that have taken place in approach and management, the administrative and official fiats thereon, present scenario, suggestions and recommendations for future management based on tested models of collaborative forest management. The findings and conclusions are stemming from a three pronged approach comprising of archival work, analysis of remote sensed data and field research data gathered in Sirumalai Hills which is part of Eastern Ghats. The research study advocates a vibrant socio-economic approach to the problem of depletion of forest resources, which envisages an active participation of local people and other stakeholders as partners in formulating policies in the management of natural resources, seeking peoples initiative and involvement in collaborative management. The book has also devoted a chapter at the end exclusively for Environmental Ethics and Future arising out of the study which analyses the current scenario in forest resource management, examining values of ethics and aesthetics in a philosophical framework situation.
