The participation of representatives of the Oregon Department of Agriculture reaffirmed the commonality of our goals in plant protection. Although few growers participated in the Conference, their presence was particularly significant, as they provided a unique perspective based on their experience in the production fields. The U.S. Department of Agriculture, CSREES, Pest Management (Smith-Lever 3(d)) program through IPPC provided funding for the Conference. Technical editing of the proceedings was under the direction of IPPC staff, with final copy editing and design by the OSU Department of Extension and Experiment Station Communications. To all of the people who made this Conference possible, our deepest appreciation. 111 Marcos Kogan integrated Plant Protection Center Oregon State University Corvallis, Oregon 97331 Oregon has had a long and distinguished history of U.S. by the year 2000. Critics complain that, accomplishments in crop protection. F.L. Washburn, depending on how one looks at 1PM, either we first entomology department head at State already have exceeded that target, or in no way are Agricultural College of Oregon, also taught the first we going to meet it.It all depends on how we course in economic entomology in 1889. Both define 1PM and how we measure progress in 1PM Washburn and A.B. Cordley were Station adoption. It would be useful to achieve consensus entomologists and published on codling moth and on a definition of 1PM, but this is not easy. On the San Jose scale in the late 1800s. Until 1911-12, IPPC web site there is a compendium of 1PM little attention was given to pests of field crops; but definitions (Bajwa and Kogan, 1997). At last count, soon after, work started on vetch, clover, alfalfa, the compendium included 67 published definitions. field peas for seed, and hay. The department I would not be surprised if by the end of this expanded with new faculty added and research conference, we did not hear of three or four new focusing on all major fruit, vegetable, and field ones. crops in the state (Richter, 1966). The first head of Botany and Horticulture was E.R. Lake (1888- Definitions usually are selected to suit one's 1891), and the first publication in plant pathology, perspective or vested interests. I personally favor "Investigations of Plant Diseases," was issued in one that considers 1PM primarily as a decision- 1889. In 1894, Moses Craig published "Cause and making system for crop protection. I feel that 1PM Prevention of Plant Diseases" (Station Bull.
