Medicinal and aromatic plants (MAPs) are globally used for the curative properties due to the presence of complex chemical substances belonging to diverse categories like alkaloids, glycosides, corticosteroids, essential oils, etc. However, with the changing climatic conditions and presence of various biotic and abiotic factors; huge gap exists between the demand and supply of raw materials. Amongst all the factors, cultivation of MAPs faces perilous damage from multifarious assemblage of microbes like bacteria, fungi, viruses, phytoplasmas, phytonematodes which pose serious threat to the total yield and bioactive potential of the plants. The present book entitled ‘Diseases of medicinal and aromatic plants and their management’ is thus a compilation of all possible scattered information which exhaustively outlines the important diseases of MAPs, their etiology with effective management strategies. The book has different chapters which extensively deals with information on the history of causal pathogen, the distribution range, symptoms, losses suffered, epidemiology and integrated pest management approaches involving cultural, chemical, biological and genetic resources being embraced across the globe. The book has authored chapters from the leading plant pathologists of India who have used extensive range of photographs, graphs and tables for making the content easy to understand not only for students but also to scientists, growers, extension workers and policy makers. Overall, the encyclopaedic nature of this books will be useful for undergraduate and postgraduate students studying courses offered on MAPs and will thus be an invaluable addition to any library.
