This book is a compilation of the most challenging and significant
chapters on the diagnosis and management of important bacterial,
fungal, viral, viroid, phytoplasma, non parasitic diseases and
various physiological disorders, in various crops. The chapters
have been contributed by eminent plant pathologists, having wide
experience of teaching and research on various crops with different
types of diseases, which cause great economic losses. The book
would be very useful for students, teachers and researchers of
plant pathology. This book highlights recent advances made in the
development of new types of resistance in host plants and
alternative strategies for managing plant diseases to improve food
quality and reduce the negative public health impact associated
with plant diseases. 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.
The book entitled "Biopesticides in Organic Farming : Recent
Advances", describes critically reviewed, key aspects of organic
farming and provides a unique and timely science-based resource for
researchers, teachers, extension workers, students, primary
producers and others around the world. This book is intended to be
a unique and indispensable resource that offers a diverse range of
valuable information and perspectives on biopesticides in organic
agriculture. It has chapters on each and every aspect related with
biopesticides in organic farming which are compiled by researchers
and eminent professors at various universities across the globe.
The wide spectrum information in various chapters with the addition
of the terms related to organic farming and concept statements is
presented in very concise manner. Features: This book is designed,
as per course curriculum of different universities offering courses
on Organic Farming, for undergraduate and post graduate students,
researchers, university professors and extension workers. The first
section provides, Overview of organic farming with special
reference to biopesticides followed by the Principles of the
applications of biopesticides in organic farming, Impact of
Environmental factors on biopesticides in organic farming,
Pesticides Exposure Impacts on Health and Need of Biopesticides in
Organic Farming, and Role of nutrients in the management of crop
diseases through biopesticides. The next section deals with the
management of various crop diseases through biopesticides of
bacterial, fungal, viral, and Insect sex hormone, Natural enemies
and Integrated Pest Management, Biotechnological Trends in Insect
Pests Control Strategy, Challenges in the popularization of
Biopesticides in organic farming, Certification process and
standards of organic farming and Marketing and export potential of
organic Products. Information presented in an accessible way for
students, professors, researchers, business innovators and
entrepreneurs, management professionals and practitioners.
Viral Diseases of Field and Horticultural Crops details the
fundamental and applied aspects of the viral diseases of field and
horticultural crops. The book opens with a historical introduction
to plant virology, important plant virologists, and landmarks. It
continues with systematic coverage of viral diseases, their
economic significance, disease symptoms, host range, mode of
transmission, diagnostic techniques, geographic distribution,
epidemiology, yield losses, and control and management of the
disease. Contributions from an international group of virologists
with a wide range of academic, research, professional, and
specialized backgrounds in plant virology makes Viral Diseases of
Field and Horticultural Crops a comprehensive and must-have
resource for those engaged in the study and research of plant
virology, microbiology, and plant pathology particularly viral
diseases and their impact on field and horticultural crops.
Applied Plant Virology: Advances, Detection, and Antiviral
Strategies provides an overview on recent developments and
applications in the field of plant virology. The book begins with
an introduction to important advances in plant virology, but then
covers topics including techniques for assay detection and the
diagnosis of plant viruses, the purification, isolation and
characterization of plant viruses, the architecture of plant
viruses, the replication of plant viruses, the physiology of
virus-infected hosts, vectors of plant viruses, and the
nomenclature and classification of plants. The book also discusses
defense strategies by utilizing antiviral agents and management
strategies of virus and viroid diseases. With contributions from an
international collection of experts, this book presents a practical
resource for plant virologists, plant pathologists,
horticulturalists, agronomists, biotechnologists, academics and
researchers interested in up-to-date technologies and information
that advance the field of plant virology.
The book has been divided conveniently into chapters dealing with
survey, diagnosis, characterization and management of the viruses
infecting papaya (Carica papaya L.). A detailed outline of the
viral diseases of papaya is given for ready reference. Described
the various types of symptoms appearing on papaya due to virus(es)
infection. Besides, this book describes the transmission, dilution
end point, thermal inactivation point, longevity in-vitro,
isolation and purification of the virus, serological and molecular
characterization, electron microscopy. Methodologies of DAC-ELISA,
RT-PCR for detection of papaya ring spot virus (PRSV) were also
described. This book deals with the eco-friendly management of the
viral diseases of papaya though antiviral agents of plant origin.
Role of Boerhaavia diffusa and Clerodendron aculeatum against viral
diseases have been described. Identification of sources of
resistance is mentioned in this book. I feel that this book would
be most useful for researchers, scientists, teachers and students
engaged in the area of plant virology.
