Overview for Encyclopedia of Plant Diseases in Agriculture and Horticulture (In 4 Volumes)
No other excuse need be offered for a second edition than the rapid output of plant-disease literature during the six years that have elapsed since the first edition. An attempt has been made to incorporate the new researches, especially those which bear directly upon the types selected for detailed consideration. In order to conserve space for the additions, it has seemed necessary to omit the detailed treatment of a few types given prominence in the first edition. Many parts of chapters have been entirely rewritten, but the limitation of space has made it impossible to include many features which might seem desirable. In the lists of important diseases at the end of most of the chapters, only types are selected, with key references which should serve as a starting point if the student wishes to make a special study of a given disease. New key references have been added and some of the older ones omitted. The author wishes here to express his gratitude for the words of appreciation and the friendly advice and criticisms which have been received from various plant pathologists in this country and abroad since the appearance of the first edition.
