Since the appearance of the 1st edition of Plant
Pathology in June 1969, tremendous advances have
been made both in the science of plant pathology
and in the publishing business. New information published
in the monthly plant pathological and related
biological journals, as well as in specialized books and
annual reviews, was digested and pertinent portions of
it were included in each new edition of the book. The
worldwide use of the book, in English or in its several
translations, also created a need to describe additional
diseases affecting crops important to different parts of
the world. There has been, therefore, a continuous need
to add at least some additional text and more illustrations
to the book with as little increase in the size of the
book as possible. Fortunately, through the use of computers,
tremendous advances have been made in the
publishing business, including paper quality and labor
costs and, particularly, in the reproducibility and affordability
of color photographs and diagrams. Plant diseases
and plant pathology come alive when illustrated
in full color and it has been the author’s dream to have
all the figures in color. Add to these advances the interest
of the author and of the publishers to spare no effort
or expense in the production of this book and you have
what we believe is the best book possible for the effective
teaching of plant pathology at today’s college level
To begin with, “Plant Pathology, 5th edition” provides
each instructor with all the significant new developments
in each area and gives the instructor choices in
the type and amount of general concepts material
(Chapters 1–9) and of specific diseases (Chapters 10–16)
he/she will cover. Each chapter begins with a fairly
detailed, well-organized table of contents that can be
used by students and instructors as an outline for the
chapter. The instructor can also use it to cover parts of
it in detail in class while some of the topics are covered
briefly and others are assigned to the students as further
reading. Each student, however, has all the latest material,
well organized and beautifully illustrated, available
in a way that is self-explanatory and, with the complete
glossary provided, can be understood with minimal
Instructors will have an even greater choice in the
kinds of specific diseases one would use in a specific area
of the country or of the world where one teaches. While
one may want to include the teaching of potato late
blight, apple scab, wheat rust, bacterial soft rot, root
knot, and some other diseases of general interest, one
often also wants to cover diseases of particular interest
in the region, both because of their regional importance
and because of their availability locally for further study
in the classroom and the laboratory. This edition makes
this possible by covering and illustrating in full color a
wide variety of diseases, some of which are important
to the grain plains of the Midwest and the northwestern
United States, others to the fruit- and vegetableproducing
Pacific and northeastern states, others to the
cotton-, peanut-, tobacco-, rice-, and citrus-vegetable
producing southern states, and so on. A special effort
has also been made to describe and to fully illustrate in
full color several diseases of tropical crops important in
different parts of the world, such as rice in the Far East,
beans in Central and South America, cassava, cacao,
and sorghum in Africa, and tropical fruits such as citrus,
papaya, coconut, and coffee in the Americas, and so on.
Instructors can pick and choose to study, in the classroom
and, if possible, in the laboratory, whatever diseases
of whichever crops they deem most significant for
the particular area and for the ever-shrinking world we
all live in.
The overall arrangement of this edition is similar to
that of previous editions. However, all aspects of the
book have been thoroughly updated and illustrated.
Newly discovered diseases and pathogens are described,
and changes in pathogen taxonomy and nomenclature
are incorporated in the text. Changes or refinements in
plant disease epidemiology and new approaches and
new materials used for plant disease control are discussed.
The chapters on diseases caused by prokaryotes
(bacteria and mollicutes), especially the one on diseases
caused by plant viruses and viroids, have been revamped
due to the large amount of new information published
in recent years about such pathogens and diseases. And
in all cases, partial tables of contents have been added
to each chapter and to its main subdivisions for better
clarity and understanding of the arrangement and inclusion
of the topics in the appropriate subdivisions. A new
feature that has been added to the book is the presentation
of a number of topics of special interest in separate
boxes. In these, the various topics are approached
from a different angle and highlight the importance of
the topic whether it has historical, political, or scientific
significance. Special attention has also been given to
highlighting the historical developments in plant pathology
and the scientists or others who contributed significantly
to these developments.
As in other recent editions, much of the progress in
plant pathology has been in the areas of molecular
genetics and its use in developing defenses in plants,
against pathogens. Discoveries in basic molecular genetics,
particularly discoveries in how plants defend themselves
against pathogens and in the development of
mechanisms to produce disease resistant plants, receive
extensive coverage. It is recognized that some of the
included material in Chapters 4 (Genetics of Disease),
5 (How Pathogens Attack Plants), and 6 (How Plants
Defend Themselves against Pathogens) may be both
too much for students taking plant pathology for the
first time and somewhat difficult to follow and comprehend.
However, the importance of that material to
the future development of plant pathology as a science
and its potential future impact on control of plant
diseases is so great that its inclusion is considered justified
if only to expose and initiate the students to these
There are numerous colleagues to whom I am
indebted for suggestions and for providing me with
numerous slides or electronic images of plant disease
symptoms or plant pathology concepts that are used in
the book. Their names are listed in the legend(s) of the
figures they gave me and in the list of “Photo Credits.”
I would particularly like to express my sincere appreciation
and thanks to Dr. Ieuan R. Evans of the
Agronomy Unit of the Alberta Agriculture, Edmonton,
Alberta, Canada, who, as editor of the slide collection
of the Western Committee on Plant Disease Control,
provided me with hundreds of excellent slides and permission
to use them in the book. I also thank Dr. Wen
Yuan Song for reviewing the chapter on “How Plants
Defend Themselves against Pathogens.” Finally, I again
thank publicly my wife Annette for the many hours she
spent helping me organize, copy, scan, and reorganize
the many slides, prints, and diagrams used in this book.
Not only did she do it better, she also did it faster than
I could have done it.
