"Information concerning fruit diseases of deciduous fruits in the United States is contained mainly in bulletins and circulars issued by the state experiment stations and the U.S. Department of Agriculture and in scattered articles in scientific journals. The only book published on this subject is now thirty-six years old and therefore does not include the many later contributions by workers in this field. It was felt that there was a pressing need for a comprehensive treatment of the subject which would be useful to research workers, teachers and practicing horticulturists. The comprehensive experience of the author in research and practical field work has promoted this attempt to collect and evaluate the extensive but scattered information on the subject and to present it in a usable form.
An attempt has been made at the same time to present a broader view of the subject than that generally included in bulletins, manuals and textbooks on plant diseases. Physiological disturbances caused by non-parasitic factors are often as destructive as those due to well-recognized parasitic organisms. In so far as these nonparasitic diseases possess definite symptoms, they are included. No attempt has been made to include insect injury except where the secondary effect of such injury leads to a definite abnormal growth condition.
Citrus and other definitely subtropical fruits are not included. The recent publication of Fawcett on "Diseases of Citrus Fruits" covers this crop.
Fruit diseases occurring in foreign countries, but not in the United States and Canada, are given scant attention unless they are of major concern in the countries where they occur. Admittedly, the viewpoint and experience of the author account for major emphasis to conditions as they exist in the United States and Canada. A number of minor diseases have been omitted, especially if their identity is not well established.
The illustrations have been selected mainly to show symptoms of the diseases. Illustrations of morphological details of the organisms have been used sparingly, since most of them (or those of related species) can be found in any text book on general plant pathology or mycology." (jacket)
