Historical Note

The Botany and Plant Pathology Department offers undergraduate and graduate degrees and conducts research on the fundamental aspects of plant biology, plant health and funcion, plant-microbe and plan-insect interactions, genomics, evolution, and ecology. The extension unit of the department addresses diseases of economically important plants in Oregon and plant diseases of worldwide significance.

Botany courses have been taught at Oregon State since the 1870s; the first plant pathology course was taught in 1895. The Department of Botany and Horticulture was established in 1888 with E.R. Lake as head. A combined Department of Botany and Forestry was active from 1904 until 1908, when a separate Department of Botany was formed in the School of Agriculture. In 1909, it was renamed the Department of Botany and Plant Pathology. Joint administration of the department by the Schools of Agriculture and Science began about 1932.

Department chairs have included Howard P. Barss (1915-1936), Charles E. Owens (1936-1947), S.M. Dietz (1947-1958), and Roy A. Young (1958-1966).

Content Description

The Botany and Plant Pathology Department Records document research, teaching, and extension programs in botany and plant diseases at Oregon State. The bulk of the records were microfilmed in the 1960s and consist of general and research correspondence pertaining to department administration and various research projects. Much of the collection pertains to research and extension activities on the diseases of tree fruits, ornamentals and nursery crops, small fruits and berries, vegetable crops and potatoes, hops, mint, and cereals; use of fungicides; and nematodes.

Reports include fungicide test results, reports of the Fruit and Ornamental Disease Management Program, and a comprehensive report and self-study prepared in 1975.

The records include correspondence with and reports to the Agricultural Experiment Station, which funded much of the research. Correspondence and reports by Howard P. Barss are part of the records; reports on the Herbarium by Helen Gilkey are also included. The teaching materials include laboratory manuals and course outlines for botany courses taught in the 1920s. Authors include W.M. Atwood and Charles E. Owens. A booklet about the department prepared in about 1990 includes profiles of all department faculty that describe their research areas and list several recent publications.

Series III:  Reports, 1908-2005

Series III consists of reports and handbooks from the 1950s through 2000s in paper format and from the 1900s through 1930s on microfilm. The more recent reports consist primarily of fungicide test results and reports of the Fruit and Ornamental Disease Management Program. Post-2005 reports of the Fruit and Ornamental Disease Management Program are part of the Extension Service Records (RG 111). A comprehensive report and self-study prepared by the department in advance of a special review in 1975 by the Cooperative State Research Service (CSRS) describes the department's faculty and staff, facilities, research program, budget, curricula, and students. The microfilmed reports were prepared for submission to the School of Science, Agricultural Experiment Station, or College administration and provide information about academic, research, and extension programs. These include reports on the Herbarium prepared by Helen Gilkey.
