Disease Management Guide For Commercial Vegetable Growers

Vegetables are a rich source of vitamins, minerals and the much needed roughage in our daily diet. These are of primary importance for an adequate and balanced human diet and contribute significantly to regional and national economy. However, the cultivation of these crops is often affected by the ravages of pests and diseases, thereby, lowering their yield potential. Diseases also cause subsequent post-harvest transit and storage losses. In the past few decades, dramatic advancements have been made in understanding the nature of vegetable diseases through in-depth investigations in host-pathogen interactions, development of molecular diagnostic tools and integration of new concepts, principals and approaches for their effective management. Indiscriminate use of chemicals for the management of vegetable diseases has led to an increase in environmental pollution and development of resistant strains of the pathogens. In the recent years, several advances have been made in eco-friendly technologies for integrated management of vegetable diseases. The book on, “Disease Problems in Vegetable Production” gives a comprehensive over-view of economic importance, symptomatology, etiology, epidemiology and management of important diseases of vegetable crops caused by fungi, bacteria, viruses, virus like organisms, mycoplasmas and nematodes. The integration of more than one management practices including genetic resistance, cultural, biological and chemical methods has been suggested to make their use more effective, economical and eco-friendly. A total of 17 chapters dealing with important diseases of vegetables like potato, tomato, crucifers, cucurbits, pea, French beans, chillies, onion, garlic, egg plant, carrot, sugarbeet, colocasia, okra and leafy vegetables have been compiled in this book. The book also includes chapters on common pathogens of vegetable crops, disease problems in nurseries, post-harvest diseases and disease problems caused by nematodes. Each chapter contains disease cycles of important diseases that will help in better understanding of the perpetuation and spread of the disease causing pathogens. Coloured photographs of disease symptoms have been included for easy identification of different diseases. The book will serve as a useful guide for students, scientists, extension workers and others associated with the discipline of vegetable pathology.

The Fruits and Vegetables manual is a reference manual on diseases which attack fruits (including berries), vegetables, and nuts. The manual identifies various types of diseases which are known to invade these plants located throughout North, Central, and South America. The recordings include diseases caused by fungi, bacteria, viruses, viroids, phytoplasmas, and nematodes. Causal disease agents are described and illustrated in some cases and diseases and disease control measures are also discussed. A manual such as this is never finished since new reports of diseases are continuously reported.

Vegetable Diseases focuses primarily on diseases that are caused by pathogens. Chapters dealing with the general principles of the causes, diagnosis and control of vegetable crop diseases are followed by crop-based chapters. Each disease entry includes a brief introduction to the disease, detailed description of disease symptoms, information on the pathogen and disease development, and suggestions on how to manage the problem. Top quality color photos illustrate the book throughout. This book will be useful to a range of professionals including research and extension plant pathologists; diagnosticians and plant lab personnel; teachers of agriculture and related subjects; university students in agriculture and related fields; commercial farmers, vegetable producers, and farm managers; agriculturalists in the fields of seed production, vegetable breeding, agrichemicals, pest control, marketing, and other subjects; government and regulatory persons dealing with agriculture; serious gardeners and hobbyists.
