t had been long felt need by scientists and vegetable growers in India and abroad to bring out a comprehensive publication on virus and virus-like pathogens infecting various vegetable crops /plants with special emphasis to the research work done in the Indian subcontinent which is considered to be the original home of several vegetables. Therefore, I decided to write my experiences on virus diseases of vegetable crops in India and abroad with a joint authorship with a well known Entomologist. Dr. K.P. Srivastava. I gained hand on experience on virus and virus-like diseases of vegetables while working at the Regional Station of Indian Agricultural Research Institute at Shimla and Kalimpong. Interestingly I did most of the work for my Ph.D on an important virus, turnip mosaic virus at Kalimpong in Darjeeling hills. I was exposed on virus and virus-like diseases of plants while working at several laboratories abroad. Finally, I gained long experience on viruses at the Advanced Centre for Plant Virology at IARI, New Delhi through National and International projects. Virus and virus-like diseases posed serious threat to vegetable production in India and elsewhere. Important vegetables grown all over the world have been listed in the book. Information has been provided on economic importance of vegetables, vegetable producing countries and world vegetable production. Viruses of vegetatively propagated vegetable crops such as potato and others are much more important economically due to perpetuation of these pathogens in these crops. Diseases caused by viruses, phytoplasmas (mycoplasma-like organisms) and viroids are among the greatest threat to vegetable cultivation all over the world. Diseases caused by these pathogens have a direct impact on export and import of horticultural plants and products. Vegetable crops are more susceptible to virus and virus-like infections. Basic information about viruses, phytoplasma and viroids and their diagnostics have been provided. The book has sixteen chapters: Introduction, followed by 15 chapters separately on nature and management of virus and virus-like diseases of vegetables. First chapter of the book provides brief introduction about vegetable crop plants, their origin in Asia, Australia, North America, and in Mediterranean regions. Other 15 chapters described the nature and management of virus and virus-like diseases of vegetables in following families: Cucurbitaceae (33 diseases on 14 crop plants), Solanaceae (61 diseases on 8 crop plants), Umbelliferae (20 diseases in 10 crop plants), Chenopodiaceae/Amaranthaceae (18 diseases in 4 crop plants), Alloideae (17 diseases in 4 crop plants), Malvaceae (4 diseases in Okra crop), Convolvulaceae (11 diseases in sweet potato crop), Poaceae (6 diseases in 2 crop plants), Araceae (2 diseases in 2 crop plants), Euphorbiaceae (9 diseases in cassava plantation), Leguminosae (65 diseases in 13 crops). In addion virus and viruslike diseases have been mentioned in Asparagus and plants used as vegetables/salad ( 18 diseases in 8 plants) and 6 diseases in papaya and 4 diseases in banana. Most of these diseases have virus aetiology but 26 diseases are caused by Phytoplasmas and a few like potato spindle tuber are associated with Viroids. Each disease and pathogen(s) associated with it have been comprehensively described in relation to their geographical distribution, economic importance, disease symptoms, transmission, vector(s), host range, indicator and assay hosts, nature and structure of associated pathogen, their genome organization, methods of detection and management. In total 109 colour plates ad 37 figures relevant to disease, in questions, have been put in the book. To manage these diseases methods like quarantine measures, eradication of infected plants and weed hosts, crop rotation and use of virus-free certified propagation material and use of pesticides to manage insects which are vector of viruses have been described in detail. Molecular breeding has been utilized to develop virus resistant plants for commercialization. The book entitled �VIRUS DISEASES OF VEGETABLE CROPS AND THEIR MANAGEMENT� is aimed to describe vegetable crops diseases caused by viruses and allied pathogens will certainly be very helpful to the students and teachers of plant virology, plant pathology, horticulture and vegetable growers. It will also help to grow virus-free vegetable crops in developing countries.
