Book Description
Downy mildew (Peronospora parasitica) is among the major devastating diseases of crucifers world-wide. Hosts of this disease include canola, cabbage, cauliflower, broccoli, kale, and various ornamental plants. This publication is a detailed literature review on downy mildew of crucifers, arranged into sections discussing the following: the disease, its symptoms on different hosts, geographic distribution, yield losses, and disease assessment methods; the pathogen's taxonomy, variability, sporulation, perpetuation, and spore germination; host-pathogen interactions in the form of seed infection, host range, disease cycle, process of infection and pathogenesis, epidemiology, fine structure, biochemical changes, and biochemical compounds; host defence mechanisms; techniques for studying host-pathogen relationships; and management practices related to cultural control, chemical control, biological control, host resistance, and integrated disease management.

Book Description
The book reviews key developments in downy mildew research, including the disease, its distribution, symptomatology, host range, yield losses, and disease assessment; the pathogen, its taxonomy, morphology, phylogeny, variability, sporulation, survival and perpetuation, spore germination, infection, pathogenesis, seed infection, disease cycle, epidemiology, forecasting, and fine structures. The book also elaborates the mechanisms of host resistance (biochemical, histological, genetic, and molecular, including cloning and the mapping of R-genes), disease resistance breeding strategies, and the genetics of host-parasite interactions. It explores disease management based on cultural, chemical, biological, host resistance, and integrated approaches; and provides suggestions for future research areas. This book offers a comprehensive guide to an economically important disease, reviewing in detail the extant body of literature. Divided into 16 chapters, each of which includes a wealth of photographs, graphs, histograms, tables, figures, flow charts, micrographs etc., it represents an invaluable source of information for all researchers, teachers, students, industrialists, farmers, policymakers, and all others who are interested in growing healthy and profitable cruciferous crops all over the world.

Book Description
Powdery mildew disease is the fourth most widespread disease in cruciferous crops and a devastating effect, causing significant losses in terms of quality and quantity in rapeseed and mustard. Powdery mildews are also a favourable host-pathosystem model for basic research on host–parasite interactions, developmental morphology, cytology, and molecular biology to identify the effector proteins/genes governing different biological functions. This book provides a comprehensive overview of all the published information in the field for researchers, teachers, students, extension experts, industrialists and farmers, and includes illustrations, photographs, graphs, figures, tables, histograms, micrographs, electron micrographs, and flow charts to aid understanding. It also describes standardized reducible techniques. The book discusses each disease in detail, describing the distribution, symptomatology, host range, yield losses and disease assessment, as well as the taxonomy, morphology, phylogeny, variability, sporulation, survival and perpetuation of the pathogen. Further, it explores topics such as spore germination; infection; pathogenesis; disease cycle; epidemiology; forecasting; fine structures; host resistance; biochemical, histological, genetic and molecular aspects such as cloning and mapping of R genes; sources of resistance; disease resistance breeding; and the genetics of host-parasite interactions and disease management.

Book Description
Emphasis in this second volume of Advances in Downy Mildew Research is on the biology of compatible interactions, forecasting and epidemiology, host specialisation, genetic variability amongst pathogen populations, novel methods for detection and systematics, and induced resistance. Two chapters focus on the related oomycete Albugo candida, which shares many pathogenic characteristics with the downy mildews and provides a valuable comparative pathosystem. Contributions on specific downy mildews include Bremia lactucae, Peronospora destructor, Peronospora sparsa, Peronospora viciae, Plasmopara halstedii, Plasmopara viticola, Pseudoperonospora cubensis and Sclerospora graminicola. Review chapters on compatibility, forecasting and systematics consider a broader range of downy mildew fungi, and compare them with other oomycete and biotrophic pathogens. The book is relevant to anyone with an interest in these unique biotrophic pathogens, either in their own right as causes of damaging diseases or as model systems for research on host-pathogen interactions. It should be read by: students, teachers and researchers in academic and research institutes; research and development personnel in the agrochemical industries; agricultural and horticultural advisers, and other extension workers.

Book Description
The book entitled “Disease Problems in Vegetable Production” 2nd edition, is specifically prepared for under and post graduate students in Agriculture/ Horticulture and range of professionals including teachers, researchers, extension plant pathologists and elite vegetable growers. The book gives a comprehensive over-view of economic importance, symptomatology, etiology, pre-disposing factors and management of vegetable diseases employing cultural, biological, host resistance, plant extracts and chemical methods as such and in anintegrated approach so that the ravages due to the diseases remain below economic threshold level. A total of 19 chapters dealing with important diseases of vegetables like potato, tomato, crucifers, cucurbits, pea, French bean, chillies and bell pepper, onion, garlic, eggplant, carrot, sugar beet, colocasia, okra and leafy vegetables have been compiled in this book. Two new chapters on diseases of ginger and diseases of vegetables under protected cultivation as well as some important diseases of different vegetable crops left out in the first edition have been added in this edition. Besides, the book also includes chapters on common pathogens of vegetable crops, disease problems in nurseries, post harvest diseases and diseases caused by nematodes. All chapters have been updated in the light of available literature up to 2017. Symptoms, disease cycles of important diseases and different structures of pathogen(s) have also been given in the book that will not only help in better diagnosis and understanding of the perpetuation and spread of the causal pathogens but will also help in the management of these diseases more effectively. Coloured photographs of disease symptoms have also been included for easy identification of vegetable diseases.

Book Description
The brassicas include an important group of oilseed crops such as canola and commercial vegetables such as cabbage and broccoli. Infection by species of the fungus Alternaria causes severe yield losses to those crops. This document compiles the most recent information on fundamental and applied knowledge of Alternaria species infecting Brassicaceae crops and weeds. It includes a review of the symptoms, geographical distribution, yield losses, and disease assessment methods of infections from the four most widely distributed species of Alternaria; information on the characteristics of the pathogen, its host range, disease cycle, process of infection, epidemiology, fine structures and electron microscopy, resistance, and phytotoxins; and techniques for disease infection and management. The document concludes with an evaluation of future strategies and priorities in the management of Alternaria diseases.
