FIELD CROP DISEASES HANDBOOK
DOWNLOAD
The purpose of Field Crop Diseases Handbook is to provide basic infor-
mation in one volume on the diseases of many of the world's impor-
tant field crops. The second edition contains considerably more informa-
tion than the first edition. The first edition contained information on
over 800 different diseases; the second edition includes information on
approximately 1,200 diseases of 25 different plants. Investigations of the
causal organisms continually contribute new knowledge or modify exist-
ing facts. Information on many of the diseases included in the first edi-
tion has either been expanded or modified in light of new research.
The purpose of the book, however, remains the same: to provide infor-
mation on diseases of field crops in one volume to workers and students
in all phases of agriculture. The organization of the book also remains
basically the same. Diseases are grouped by causal organism and are
then listed in each group alphabetically by common name. While some
may criticize this method due to the variation in common names, it has
proven to be a helpful way to categorize diseases, especially for nonplant
pathologists. To facilitate finding a disease, other common names for the
same disease are listed.
The writing of such a book, of necessity, entails some frustration.
Taxonomically, genera and species of some organisms have undergone
numerous changes. However, some of these changes may not be univer-
sally accepted. Therefore, the use of a latin binomial for a causal organ-
ism may not be standard among different scientists working on the same
organism. Terms and descriptions may vary among plant pathologists
and other scientists. Although, in my judgment, I have attempted to
select the most common latin binomials and terms, I ask the indulgence
of those who may not agree with my choices.
Most important, the value of a book such as this lies in its usefulness
to its intended audience. If this book helps one student to identify the
cause of a disease or one agricultural professional to understand how a
disease happens, then its worth is vindicated.
