Book Description
Seeds provide an efficient means in disseminating plant virus and viroid diseases. The success of modern agriculture depends on pathogen free seed with high yielding character and in turn disease management. There is a serious scientific concern about the transmission of plant viruses sexually through seed and asexually through plant propagules. The present book provides the latest information along with the total list of seed transmitted virus and viroid diseases at global level including, the yield losses, diagnostic techniques, mechanism of seed transmission, epidemiology and virus disease management aspects. Additional information is also provided on the transmission of plant virus and virus-like diseases through vegetative propagules. It is also well known that seed transmitted viruses are introduced into new countries and continents during large-scale traffic movements through infected germplasm and plant propogules. The latest diagnostic molecular techniques in different virus-host combinations along with disease management measures have been included. The book shall be a good reference source and also a text book to the research scientists, teachers, students of plant pathology, agriculture, horticulture, life sciences, green house managers, professional entrepreneurs, persons involved in quarantines and seed companies. This book has several important features of seed transmitted virus diseases and is a good informative source and thus deserves a place in almost all university libraries, seed companies and research organizations.

Book Description
This book provides a practical guide to the commonly used detection methods for seed-transmitted viruses and viroids affecting both tropical and non-tropical crops. The first part describes important aspects of seed-transmitted viral diseases. The second and main part contains principles of the detection techniques and step-by-step protocols accompanied by method optimization and comments. Most of the described techniques can be equally applied to plant viruses and viroids other than seedborne ones. This book will be of significant interest to those working in seed testing laboratories and students and teachers within plant pathology and seed science.

Book Description
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.

Book Description
Plant virus and sub-viral pathogens pose severe constraints to the production of wide range of economically important crops worldwide. The crops raised both through true seed and vegetative propagated materials are affected with number of virus and virus-like diseases. The virus may enter into plants through seed planting materials or by vectors. Once the virus is in the field, it multiplies and spreads following definite patterns depending upon the nature of the vector and agro-meteorological conditions. Disease free crops and plants are great economic and social importance in feeding the world's population. Detection of virus and sub-viral agents at initial stages of infection is critical to reduce economic losses. For nearly two decades, ELISA and its variants played a major role in large scale virus testing and also in the production of virus-free planting materials.

Book Description
Plant Diseases and Vectors: Ecology and Epidemiology is the fourth in a five-volume series of books on vectors of plant disease agents. It is comprised of 10 chapters representing the expertise of 13 outstanding scientists from a total of seven different countries. This book begins with a discussion on the ecological involvement of wild plants in plant virus pathosystems. This is followed by the principles and applications of enzyme-linked immunosorbent assay (ELISA) in diagnosing plant viruses and monitoring their movement in the environment. The next two chapters detail the epidemiologies of diseases caused by leafhopper-borne viruses, mollicutes, and rickettsia-like organisms. This book also covers the developments in understanding the importance of helper agents to the transmission ecologies of many aphid-borne plant viruses. It also encompasses the factors that can contribute to the epidemiology and control of a disease affecting a major agricultural crop of the world. A vector of plant viruses not covered in earlier volumes of the series (the host plant, itself) and the man-made epidemiological hazards in major crops of developing countries are also described. This volume will broaden the knowledge of transmission ecology and disease epidemiology, not only by serving as a valuable supplemental textbook, reference work, and bibliographical source, but also by catalyzing novel syntheses of thinking and stimulating further research in the area.

Book Description
Pathogens, Vectors, and Plant Diseases: Approaches to Control is a collection of papers that discusses how vector host interactions, vector ecology, and disease epidemiology can be applied to disease prevention and control. The book deals with innovative strategies pertaining to control of vector-borne viruses and viral infections in plants. One paper discusses nonpesticidal control of vector-borne viruses including soil solarization that uses solar energy for crop protection, and insect sterilization through radiation, chemosterilants or genetic modifications. Another paper discusses chemicals that interfere with nucleic acid and protein synthesis; as these interactions pose no hazards to animal (mammals), the chemicals are suitable for controlling viral diseases. One author examines the use of oil sprays and reflective surfaces as a means of controlling plant viruses transmitted by insects. In the United States, the entry of vector-borne plant pathogens is controlled by plant quarantine. One author lists several ways in effective quarantine procedures, as well as, the safe importation of potential vectors as cultures. This book is suitable for environmentalists, biologists, conservationists, agriculturists, botanists, and researchers in botany and plant genealogy.
