This book is the first of the 3-volume Innovative Approaches in Diagnosis and Management of Crop Diseases, which provides an abundance of new research and information on major diseases of various crops along with new techniques and technology for the detection of plant pathogens along with appropriate management strategies. Divided into three volumes and with chapters written by renowned and expert scientists working in different areas of plant pathology, the volumes cover important diseases of crops incited by bacteria, fungi, viruses, viroids, phytoplasma, and nematodes. It addresses these disease challenges to commercial field and horticultural crops and their management. Chapters cover recent advances in diagnosis and detection of diseases of rice, wheat, pulses, guava, aonla, cucurbits, ginger, sesame, cotton, pigeonpea, field pea, small millets, maize, and cruciferous vegetables as well as ornamental plants. Innovative Approaches in Diagnosis and Management of Crop Diseases: Volume 1 focuses on the Mollicute class of bacteria. It looks at the detection, diagnosis, and management of phytoplasma diseases and viroids, CRISPR-Cas9 genome editing in plants for virus resistance, next-generation sequencing technologies, and more. Key features: Presents diverse research of leading plant pathologists on detection, diagnosis, and management of crop diseases Shares innovative and emerging techniques for diagnosis and management of major plant diseases Covers a vast array of important crops and their diseases Volume 2 looks specifically at the diseases of field and horticultural crops, while Volume 3 reviews the advances in the use of nanomolecules and biocontrol agents. Diagnosis and management of biotic stresses play a pivotal role in efficient agriculture production, and together, these volumes of Innovative Approaches in Diagnosis and Management of Crop Diseases provide reviews of crucial research to effectively advance the detection, diagnosis, and management of crop diseases.
