Host Plants and Their Diseases
The information telescoped into this section is taken in large part from the records of the Plant Disease Survey as given in the Plant Disease Reporter, Plant Diseases and from the Index of Plant Diseases in the United States, Agriculture Handbook 165, U.S. Department of Agriculture. I have added to this recent records as I have run across them in the literature and a few personal observations. Inevitably I have missed some, and there will be many more appearing while this text is in press; so the lists cannot be regarded as complete. There are a great many more records than in the first edition, but with surveys bringing new reports every day, any such list is out of date by the time it is typed; and by the time it is printed and available, many months later, it is sure to be far from complete. This check list is offered as a helpful guide, a foundation on which to build. It is by no means the last word.
