This edited volume covers latest information and developments on the Detection, Diagnosis and Management of Air-Borne Diseases of Agricultural Crops across the globe. The main aim of this book is to address the scientific and practical significance of detection, diagnosis and management of air-Borne plant pathogens. With the advancement of science, OMICs approaches playing crucial role in the efficient and accurate detection of pathogen propagules present in the air or on the plant surface. This book volume cover almost all molecular techniques used for detection and diagnosis of air-borne phyto-pathogens. Similarly, all possible management practices with detailed description are discussed in the present book volume. Special attention has been given on the microbe-mediated management of air-borne disease. Among the more recent strategies, resistance induced by environment-friendly elicitors of microbial origin and/or rhizosphere/phyllosphere microbes has emerged as a promising supplement in the approaches to crop protection. This book covers all spheres of microbial management viz., bio-resources, diversity, ecology, and functioning of microbial biocontrol agents, host–parasite interaction, strategies to characterize microbial bioinoculants, application of microbial bio-pesticides and regulatory mechanisms pertaining to commercialization of biopesticides. This book is of interest to teachers, researchers, crop protection scientists, capacity builders and policymakers. Also, the book serves as additional reading material for under-graduate, post-graduate, and post-doctorate fellow of agriculture, forestry, ecology, life science, and environmental sciences.
