Summary : A Textbook of Plant Pathology provides comprehensive coverage of the fundamentals of plant pathology. It offers an introduction to plant pathology for those new to the field. The text covers approximately 50 diseases in crop plants, providing details of symptoms, disease cycle and control measures. The book is divided into two parts, covering the principles of plant pathology and important plant diseases in crops. The section on principles of plant pathology includes a history of plant pathology, symptoms of plant diseases, epidemiology and forecasting of plant diseases, host-parasite inter-relationships and their interactions, the effect of climatic conditions on plant diseases, physiologic specialization, defence mechanisms, methods of studying plant diseases, and principles of plant disease control. Every disease discussed consists of causal organism, symptoms, disease cycle, breeding, disease-resistant varieties and chemical control methods. The book also includes a list of periodicals on plant pathology.

Summary : Plant Disease An Advanced Treatise, Volume II: How Disease Develops in Populations deals with the epidemiological aspect of disease in population of plants. Comprised of 18 chapters, this volume discusses the comparative anatomy, methods of research, instrumentation, computer simulation, and genetic basis of epidemics. After briefly discussing the sociology of plant pathology, the book presents the comparative anatomy of epidemics in terms of their structure, patterns of development, and dynamics. This volume describes the rational processes of epidemiological research and how they differ from the processes used to investigate disease in individual plants. A chapter examines the instrumentation for measuring the weather component, including temperature, humidity, air movement, and irradiance. Other chapters discuss the measurement of disease on whole living plants; the theory and measurement of inoculum potential; the dispersal of pathogens in both time and space; and the movement and maintenance of infectivity by pathogens that operate below ground. This volume also deals with computer simulators of plant disease and the use of predictive models to forecast epidemics for management decision making. It describes some general patterns of changes in plant-part susceptibility with time for various groups of diseases caused by fungi or viruses. A discussion on the problems of genetic uniformity and susceptibility and the breeding and deployment strategies needed to cope with these problems is included. Other chapters examine the influence of climate and weather on epidemics; the analysis of the geographical and climatic distribution of plants in various parts of the world; and the hazardous practices that have favored epidemics. Lastly, the probabilities of success for quarantines against diseases of various types are provided. This volume is an invaluable source for plant epidemiologists and pathologists, botanists, and researchers.

Summary : The book entitled “Plant Pathology at a Glance” has been written exclusively for under graduate and post graduate students of general Botany, Mycology, Microbiology, Plant Virology, Plant Bacteriology, Plant Nematology and Plant Pathology. It covers core courses prescribed by most of the Universities and Institutions. The book has been divided into fifteen chapters dealing with difference aspects of Plant Pathology and its sub disciplines. Plant diseases incited by different biotic and abiotic pathogens have also been described in brief, making the book comprehensive, informative and all in one.

Summary : Excerpt from A d104-Book of Mycology and Plant Pathology The following pages represent in a much extended form the lectures and laboratory exercises given by the author before his botanic classes at the University of Pennsylvania, and before public audiences else where, especially, Farmers' Institutes with which he has had three ye'ars' experience as a lecturer in Pennsylvania. The arrangement of the text has been suggested by the needs of the classroom and from an acquaintance with similar work in other colleges and universities in America. It is hoped that the book and the suggestions, as to teaching which it contains, will appeal to those responsible for similar courses. The keys are given with the anticipation that they will prove useful to the student and teacher who desire exercises in the classification of the fungi: The illustrations have been chosen with care, and credit is given in all cases for those borrowed from other books and monographs.

Summary : Plant Pathology has an important role to play in devising strategies suitable for sustainable agriculture. Some of the important steps to be taken by plant pathologists include the development of eco-friendly mechanisms of disease control through the use of biological resources, enhancing the resistant mechanisms of the plant through molecular means as well as studies on the interactions of biotic and abiotic stressors. The diversity of Agriculturally Important Microorganisms is far more than what we have found out till date and the function of these important microbes in agro-ecosystems is also equally diverse. The ability of plant growth promoting rhizobacteria, actinomycetes, plant growth promoting fungi, mycorrhiza, to influence plant growth depends upon the diverse mechanisms like phosphate solubilization, biological nitrogen fixation, phytohormone production, siderophore production, biological control of plant pathogens and direct or indirect induction of disease resistance. Application of these beneficial microorganisms in enriching soil and enhancing crop production will not only change the scenario of using harmful chemical fertilizers but will also open up new dimensions for utilizing microbial resources for sustainable agricultural practices. The present review covers a wide spectrum of articles which are pertinent in the present day context and gives an indication to readers of the role of plant pathology in the current agricultural scenario.
