The book “Basics of Plant Pathology” is a comprehensive academic text designed for students
and researchers, focusing on the principles and applications of plant disease science. The
content is structured in accordance with the prescribed syllabus and aims to provide a
systematic understanding of plant diseases, their causes, diagnosis, and management. The book
begins with the fundamentals of plant pathology, including its history, scope, and
importance, along with an analysis of crop losses caused by phytopathogens. It explains the
classification of plant diseases based on symptoms and causal agents, distinguishing animate
and inanimate factors. The role of major plant pathological institutes such as IARI and
ICRISAT is also highlighted. Further, the text covers seed pathology and air-borne
pathogens, emphasizing their role in disease transmission and crop health. Methods for
studying these pathogens are discussed in detail. Diagnostic approaches, including field and
laboratory techniques and Koch’s postulates, are presented to strengthen the scientific
understanding. The second part of the book focuses on important plant diseases across
various crop groups, including cereals, pulses, vegetables, oilseeds, cash crops, ornamentals,
weeds, and trees. Each disease is studied with respect to symptoms, causal organism, disease
cycle, and management practices. Plant pathology is a vital discipline within agricultural
sciences that deals with the study of plant diseases and their management. With increasing
challenges in agriculture due to climate change, emerging pathogens, and the need for
sustainable crop production, understanding plant diseases has become more important than
ever. This text is intended not only to help students succeed in examinations but also to build
a strong foundation for future studies and careers in plant pathology, agriculture, and related
fields.
