Plant pathology can be defined as the scientific study of diseases in plants caused by pathogens and environmental conditions. It comprises the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, management of plant diseases, and how they affect humans and animals. Although all plants are subject to diseases, some plant varieties are more vulnerable to outbreaks of diseases, whereas others are more resistant to them. The study of plant pathology aims at preserving the environment, growing healthy crops, ensuring adequate food supply, and discovering new ways of controlling plant diseases. This book explains the emerging trends and innovative models around prospective developments with respect to plant pathology. Some of the diverse topics covered herein address the varied branches that fall under this category. This book will serve as a valuable source of reference for aspiring plant pathologists, students, and researchers.
