The information on pest and disease management under protected cultivation of horticultural crops is very much scattered. There is no book at present which comprehensively and exclusively deals with the above aspects. This book deals with pests and diseases (fungal, bacterial, viral, and nematode) in protected horticultural crops (fruits, vegetables, and ornamentals) in detail using physical, cultural, chemical, biological, host resistance, and integrated methods. Book also contains chapters on Fungal Plant Pathogens and Symptomology, Black Sigatoka of Banana and its Control, Diagnosis of Plant Disease, Physiological Disorders and their Management, Management of Citrus Canker, Management of Plant Diseases, Plant Pathogen Nano-diagnostic Techniques, Disease and Pest Management in Organic Agriculture, and Integrated Disease Management (IDM) This book will be of immense value to the scientific community as a whole involved in teaching, research, and extension activities. The material can also be used for teaching postgraduate courses. The book can serve as a very useful reference for policy makers and practising farmers.
