This book is organized into two major parts encompassing 16 chapters that discuss general aspects of plant diseases and specific plant diseases caused by various microorganisms.
This edition includes chapters or sections on diseases caused by mycoplasma-like organisms, rickettsia-like bacteria, viroids, and protozoa. Information on the genetics of plant diseases, the development of resistant varieties, and their vulnerability to new pathogen races is added in this release. It also includes information on the development of epidemics. The presentation of these topics is followed by a discussion on systemic fungicides and biological control of diseases, as well as postharvest diseases of plant products. Furthermore, this edition also explains mycotoxins and mycotoxicoses, as well as techniques of isolation, culturing, indexing, and identification of pathogens. It also studies mycorrhiza and root-nodule bacteria.
Considerable chapters describe diseases caused by fungi and those caused by bacteria, which have been organized in logical, cohesive groups according to their most important symptoms. Diagrams of disease cycles, groups of pathogens and symptoms, and techniques and concepts of plant pathology are incorporated in each chapter. Moreover, this edition provides numerous photographs (macroscopic, microscopic, electron micrographs, and scanning electron micrographs) that illustrate concepts, pathogens, and symptoms.
Teachers and students who are interested in plant pathology and plant diseases and control will find this book very helpful.
