In the preparation of Westcott's Plant Disease Handbook referenees have been reviewed that cover a eentury of scientifie reporting. An attempt has been made also to keep abreast of eurrent literature. To eite all of the individual articles that have been helpful would fill another book. The bibliography presented here is a selected small sampling of the field surveyed, with emphasis on sources eonsulted in making nomenclatural decisions. Periodicals that are regularly reviewed include Plant Disease, Phy­ topathology, Review of Applied Mycology, Journal of Economic Entomology, A.I.B.S. Bulletin (Agricultural Institute of Biological Scienees), Biological Ab­ stracts, Agricultural Chemicals, NAC News (National Agricultural Chemicals Association), Arborist's News, Proceedings of the National Shade Tree Confer­ ence, American Fruit Grower, American Vegetable Grower, Farm Journal, The Garden Journal (New York Botanical Garden), Plants and Gardens (Brooklyn Botanie Garden), The National Gardener (National Council of State Garden Clubs), publieations of many of the state garden clubs, most of the pop­ ular garden magazines, yearbooks and magazines of several single plant societies. In addition, there are numerous bulletins, cireulars, and spray sehedules from state experiment stations. The following referenees provide eoverage in depth of the eurrent tax­ onomy of the major types of plant pathogens.

Let me repeat that the references cited are a mere sampling of the vast amount of material published on plant diseases. Most plant pathologists will have access to the Plant Disease Reporter, Plant Disease, Phytopathol­ ogy, Review of Applied Mycology, Mycologia, Biological Abstracts, Journal of Economic Entomology, Agricultural Chemicals, NAC News, Arborists' News, Proceedings of the International Shade Tree Conference, and other technical publications. Gardeners will find information on plant diseases in the pub­ lications of single plant societies, such as the American Camellia Society and the American Rose Society. State agricultural experiment stations have a wealth of material. Govemment publications are available from the Su­ perintendent of Documents, U.S. Govemment Printing Office, Washington, DC20402. Index

This is a selective index. It inc1udes common and Latin names of the host plants in Chapter 4, common names of the diseases described in Chapter 3, and Latin names of their pathogens. Entries under plant names are chiefly for providing cross references to disease names, and are not to be construed as providing a complete checklist of the diseases of each plant. For that, the host section itself must suffice. Orders and families given in Chapter 2 are indexed, as are genera described in Chapter 3. Chemicals used in Chapter 1 are indexed, but not their use in control of specific diseases. Italic type indicates illustrations.
