Plant Pathology and Plant Diseases


Book Description

This textbook provides a comprehensive introduction to all aspects of plant diseases, including pathogens, plant-pathogen interactions, their management, and future perspectives. Plant diseases limit potential crop production and are responsible for considerable losses in agriculture, horticulture and forestry. Our global food production systems are under increasing pressure from global trade, climate change and urbanization. If we could alleviate the losses due to plant diseases, we would be able to produce roughly 20% more food - enough to feed the predicted world population in 2050. Co-authored by a group of international teachers of plant pathology who have collaborated for many years, the book gives expert and seamless coverage. Plant Pathology and Plant Diseases: Addresses major advances in plant-pathogen interactions, classification of plant pathogens, and the methods of managing or controlling disease Is relevant for a global audience; it covers many examples of diseases with an impact worldwide but with an emphasis on disease of particular importance in a temperate context Features over 400 striking figures and colour photographs It is suitable for graduate students and advanced undergraduates studying plant pathology, biology, agriculture and horticulture.




Essential Plant Pathology


Book Description

Provides an explanation of how plant diseases are diagnosed, the 'plant disease triangle', how to determine the cause of a specific disease, what 'biotrophs' and necrotrophs are, disease cycles and how they can be utilized. Specific chapters address plant diseases caused by fungi, bacteria, nematodes, viruses, parasitic flowering plants, abiotic factors of the environment including light, temperature, and atmospheric gases, pathogens, how people influence plant disease epidemics, the prevention or management of plant disease epidemics, and more.

FUNDAMENTALS OF PLANT PATHOLOGY


Book Description

This book is based on the syllabus prescribed by the Indian Council of Agricultural Research, New Delhi, for the first and second year undergraduate students of plant pathology in State Agricultural and Horticultural Universities and hence, is of special importance to these students. The text, conveniently divided into 13 chapters, deals with fundamental aspects of plant pathology viz., scope and objectives, importance of plant diseases, history and development of plant pathology, theory of plant diseases, causes of plant diseases (biotic, abiotic and plant viruses with representative examples) symptoms, general characteristics of plant pathogens, classification of phytopathogens, growth and reproduction of plant pathogens including replication of plant viruses, liberation or dispersal of plant pathogens, their survival and types of parasitism and variability in plant pathogens. At the end of each chapter, important questions have been provided for the benefit of the students. Diagrams, convincing tables and suitable graphs/illustrations are furnished at appropriate places. A complete bibliography and apt subject index are appended at the end. Besides undergraduate students, this book will also serve as a basic guide to meet the requirement of teachers/researchers in plant pathology and related fields.




PRINCIPLES of PLANT PATHOLOGY (Pathogen and Plant Disease)


Book Description

Plant Pathology comprises art of treating a sick plant as well as science of understanding the nature of the diseased plant. Primarily aimed to cater to the needs of undergraduate students, this book provides comprehensive treatment of fundamental facts, terminology and general aspects of Plant Pathology. it provides an introduction to the subject for beginners in this field. it can also serve as a laboratory manual.CONTENTS1.introduction 2.

Diseases of Trees and Shrubs


Book Description

Diseases of Trees and Shrubs is a comprehensive pictorial survey of the diseases of, as well as the environmental damage to, forest and shade trees and woody ornamental plants in the United States and Canada. An authoritative reference, it is also a reliable and handy diagnostic tool that will simplify the identification of specific plant diseases by focusing on signs and symptoms that can be seen with the unaided eye or with a hand lens. This long-needed book gives readers complete, up-to-date information in an easily understood and convenient way. Each of the 247 color plates faces a page of explanatory text covering the biology and ecology (including host and geographic ranges) of the disease-causing agents (pathogens), a list of key references (there are more than 2,250), and, in some cases, black-and-white illustrations of pathogens. Selected information about biological and cultural control is provided. Scientific terms other than Latin names of pathogens are used only when necessary, and a glossary of terms and a comprehensive index are included. The color plates contain more than 1,700 illustrations of the diseases and injuries that some 350 biological agents and environmental factors cause to more than 250 species of plants. The book also serves as a guide to hundreds of other diseases related to those shown. The authors have used three levels of organization for this book. At the first level, diseases caused by biological agents are separated from those caused by environmental stimuli. At the second level, most diseases are grouped according to the plant part affected: leaves, twigs, limbs, roots, trunks, or the entire plant. At the third level, diseases are presented according to the taxonomic relationships among the pathogens. For this major project, the authors examined and photographed diseases and environmental damage in the field, visiting more than 50 states and Canadian provinces. Their book reflects the most important developments in fungal biology and taxonomy, plant bacteriology, virology, and environmentally induced stress in plants. It summarizes information about newly discovered diseases and provides up-to-date accounts of olds ones. Diseases of Trees and Shrubs can be profitable reading for anyone whose technical training does not extend beyond general biology, yet will also be informative to advanced students and plant pathologists. It will be welcomed by agricultural and horticultural advisers, plant inspectors, arborists, nursery professionals, landscapers, foresters, and urban planners. Wayne A. Sinclair is a Professor of Plant Pathology, Howard H. Lyon is Biological Photographer (retired), Department of Plant Pathology, and Warren T. Johnson is Professor of Entomology, all at Cornell University.
