Seed-Borne Diseases of Agricultural Crops: Detection, Diagnosis & Management by Ravindra Kumar,Anuja Gupta Pdf
The global population is increasing rapidly, and feeding the ever-increasing population poses a serious challenge for agriculturalists around the world. Seed is a basic and critical input in agriculture to ensure global food security. Roughly 90 percent of the crops grown all over the world are propagated by seed. However, seed can also harbour and spread pathogens, e.g. fungi, bacteria, nematodes, viruses etc., which cause devastating diseases. Seed-borne pathogens represent a major threat to crop establishment and yield. Hence, timely detection and diagnosis is a prerequisite for their effective management. The book "Seed-Borne Diseases of Agricultural Crops: Detection, Diagnosis & Management" addresses key issues related to seed-borne/transmitted diseases in various agricultural crops. Divided into 30 chapters, it offers a comprehensive compilation of papers concerning: the history of seed pathology, importance of seed-borne diseases, seed-borne diseases and quarantine, seed health testing and certification, detection and diagnosis of seed-borne diseases and their phytopathogens, host-parasite interactions during development of seed-borne diseases, diversity of seed-borne pathogens, seed-borne diseases in major agricultural crops, non-parasitic seed disorders, mechanisms of seed transmission and seed infection, storage fungi and mycotoxins, impact of seed-borne diseases on human and animal health, and management options for seed-borne diseases. We wish to thank all of the eminent researchers who contributed valuable chapters to our book, which will be immensely useful for students, researchers, academics, and all those involved in various agro-industries.
Seed Borne Diseases: Ecofriendly Management by Arun Arya,Cecilia Monaco Pdf
Indian agriculture has witnessed spectacular advances in agricultural production in the last few decades. This was possible through green revolution in mid 60s leading to the country’s remarkable achievement in food grains and edible oil production. Seed has always been regarded as the most vital, basic and critical input in agriculture. It is interesting to note that today seed demand of only 10% farmers is met. Efforts are needed to provide good quality certify seeds to farmers. In recent years the awareness for seed health has increased among the growers, traders, and consumers. In post-GATT era and with emergence of WTO, seed health has assumed the global concern. Infection of seed borne pathogens results into seed rots, seedling decay, pre and post emergence mortality, distortion, discoloration, reduced seed size and shrivelledness of seeds. Their study and identification is primarily required to achieve satisfactory control. The book will be of great help to students, researchers, and people engaged in seed production activities. In this book, information about different seed borne diseases is presented in 20 chapters. There is an urgent need to find out effective, alternative methods of diseases control, which are less harmful to human beings and environment. There are chapters dealing with botanical pesticides and quarantine regulations. A chapter describes molecular aspects involved in seed borne diseases. The contents are divided into two parts (I) Seed borne diseases and (II) Wilt and foliar diseases and their control methods. Ecofriendly measures to control seed borne diseases are dealt in detail. The book provides comprehensive and integrated information on management of seed health written by experts in the field.

Having entered into 21st century advancements in the Diagnosis of Plant Pathogens and Plant Disease Management need to be closely examined and adequately applied, so that newer challenges facing plant pathology could be adequately addressed in attaining food security for the growing population. Substantial advancements have been made in terms of expanding knowledge base of the biology of plant-microbial interactions, disease management strategies and application and practice of Plant Pathology. Application of molecular biology in Plant Pathology has greatly improved our ability to detect plant pathogens and in increasing our understanding, their ecology and epidemiology. Similarly, new technologies and resources have been evolved for the development of sustainable crop protection systems by different control strategies against various pests and pathogens that are important components of the integrated pest management programme. Natural products and chemical compounds discovered as a result of basic research and molecular mechanisms of pathogenesis have led to the development of “biorational” pesticides. Biological control has been found to be the most significant approach to plant health management during the twentieth century and promises using modern biotechnology, to be even more significant in the twenty-first century.
Crop Diseases by Darwin Henry, H. Lewin Devasahayam Pdf
Plant diseases are among the important factors that are responsible for causing yield loss in crop production. The loss due to diseases alone is estimated to be around 26 per cent. Diseases may attack at any stage of the standing crop, from seedlings till maturity of the crop. They may affect different parts of the plants, such as foliage, stem, root, flowers or seed and cause various types of symptoms, while the diseases such as wilt affect the entire plant. All these ultimately result in the reduction of yield and poor quality of the produce. Further, many pathogens continue to attack the stored grains and stored produce, and cause spoilage. To save the crops from diseases caused by pathogens and thereby to increase crop production, it is imminent that diseases have to be controlled by any means. To adopt various strategies for the control of pathogens, one should have some basic knowledge about the symptoms produced by the pathogens, their life cycle, mode of survival and spread, and the stage at which the host is most vulnerable to attack by the pathogens. Most of the cultivated varieties of different crops are susceptible to one disease or another, while some others are susceptible to many diseases. Even resistant cultivars of some of the crop species may become susceptible to some specific diseases in course of time as a result of development of new physiologic races of the pathogen by hybridization or natural mutation or when the environmental conditions are highly favorable for the pathogen and not quite favorable for the host. In this book the authors have given a detailed account of the major diseases of important field crops and horticultural crops, and their management. The text is substantiated with many hand-drawn illustrations, which are of excellent quality and in fact it is the highlight of the book. A on important edible mushrooms commonly grown in India, methods of cultivation of different mushrooms, diseases and pests attacking mushroom beds and mushrooms is also included in the book. This may be quite useful to emerging entrepreneur The book, which has been compiled as per the undergraduate syllabus of agricultural institutions, will also be of use to postgraduate students and to those working in the department of agriculture.
During the past twentieth century, plant pathology has witnessed a dramatic advancement in management of plant diseases through in-depth investigations of host parasite interactions, integration of new concepts, principles and approaches.
