From Ohio to Minnesota—The Road Trip of the Century!What happens when you put 50 plant pathologists on a bus for a 12-hour road trip? That’s exactly what students, staff, and faculty from The Ohio State University intend to find out as they travel to the APS Centennial Meeting on the football team’s bus.
Mike Boehm, professor and chair of the Department of Plant Pathology at The Ohio State University, said the idea to take the trip stemmed from a discussion he and Larry Madden, professor and associate chair, recently had with a group of students. “During the meeting someone said off the cuff, ‘Wouldn’t it be cool if we could take a bus to the meeting?’ and I responded ‘Wouldn’t it be cool if we could take the football team’s bus!’ ” Boehm said. And the rest, well, is soon to be history—APS history.
Not only is taking the bus lighter on the wallet at $150 per passenger round trip, the ride-sharing also leaves a lighter carbon footprint, making the trip both economically and environmentally friendly.
The bus will leave Columbus at 10:00 a.m. on Saturday, July 25, and arrive in Minneapolis around 10:00 p.m. To pass the time, a number of fun activities are planned. One will be to chronicle the
entire trip with a blog that will include photos and stories that come out of the trip.
“We are really using this trip as a chance for students, faculty, and staff to get to know each other,” Boehm said.
The bus can hold a maximum of 54 people—47 have signed up to ride to the APS Centennial Meeting. While more than half of the department’s faculty has signed up, the majority of riders will be graduate and undergraduate students.
“This also is a great way for students, particularly our international students, to see a part of the country that they may not have a chance to see,” Boehm said. n

Plant pathology has come a long way in the century since APS was founded. Can you image what it might have been like sitting in the audience at the first APS annual meeting? Now is your opportunity to take a few moments and step back in time during this special Centennial Session being held on Monday, July 28. The session format will not only examine the state of the discipline of plant pathology in 1908 via historical presentations on phytobacteriology and chestnut blight, it will also take a unique look forward to illustrate the progress of our science in the last 100 years.
Erik L. Stromberg, professor and extension plant pathologist, Department of Plant Pathology, Physiology and Weed Science, Virginia Polytechnic Institute and State University, will moderate the session. Sandra Anagnostakis, Department of Plant Pathology and Ecology, The Connecticut Agricultural Experiment Station, will be Flora W. Patterson during the first 1908 presentation. She will be dressed in period clothing and have some of the lantern slides from the original presentation based on the paper “The chestnut bark disease” of H. Metcalf and J. F. Collins, Bureau of Plant Indus-try, USDA, which was presented at the first APS meeting held in Boston in 1909 and the abstract published in Science in 1910. The chestnut bark disease was first identified in 1904 when samples
were sent to the Bureau of Plant Industry from the New York Zoological Park. In contrast, Gary Griffin, professor emeritus, Department of Plant Pathology, Physiology, and Weed Science, Virginia Polytechnic Institute and State University, will provide the contemporary presentation, “Recent advances in chestnut blight research and management of chestnut blight on American chestnut.” During and following the killing of about 3.5 bil-
lion canopy American chestnut trees in eastern forests by chestnut blight in the first part of the twentieth century, research was initiated by state and federal agencies to restore the American chestnut to these forests. At this time, several approaches are showing promise for American chestnut restoration. These include breeding for blight resis-tance by backcrossing American chestnut–Chinese or Japanese chestnut hybrids to American chestnut for several generations; intercrossing large, surviving American chestnuts with low levels of blight resistance through several generations; inoculating blight-susceptible saplings and large, surviving American chestnut grafts or seedlings with hypovirulent strains of the chestnut blight fungus; producing transgenic American chestnuts; and using integrated
approaches that include the above and forest management practices, such as site selection and management of forest competition. The present status of research and potential of each of these approaches will be discussed.
For the presentations on phytobacteriology, George H. Lacy, professor emeritus, Department of Plant Pathology, Physiology and Weed Science, Virginia Polytechnic Institute and State University, will be dressed in period clothing and will portray Erwin Smith, USDA. The presentation will use illustrations from Smith’s original treatise on “Bacteria in relation to plant diseases” published in 1905 and 1911. This was the “Golden Age” of phytobacteriology. Following Fischer-Smith debates as to whether bacteria caused plant diseases, American plant pathologists began describing the bacterial causal agents of diseases. At the inaugural meeting of The American Phytopathological Society held in Boston, Smith presented descriptions of three bacterial agents of disease.
Descriptions of these bacteria from this APS meeting and his treatise, “Bacteria in relation to plant diseases,” vol. 1, 1905, and vol. 2, 1911, will be compared with Bacillus phytophthorus. Providing the contemporary perspective, Jeffrey B. Jones, professor, Department of Plant Pathology, University of Florida, Gainesville, will present, “Contemporary description of phytopathogenic bacteria: How they are described and how they should be described.” Biochemical, morphological, immunological, and molecular methods for bacterial description and phylogenetic analyses will be discussed.
Make sure to mark this unique session on your meeting agenda for the APS Centennial Meeting. n

New Editors Named to Plant DiseaseThree new senior editors recently joined the Plant Disease Editorial Board. To acquaint APS members with the new board members, brief biographies are presented.
Craig R. Grau, senior editor, is a professor in the Department of Plant Pathology at the University of Wisconsin-Madison, where he has held research, extension, teaching, and administrative assignments since 1976. He earned his B.S. and M.S. degrees in plant pathology from Iowa State University and his Ph.D. degree in plant pathology from the University of Minnesota. He spent 1 year as a research associate at North Carolina State University. Research and extension interests include etiology and pathogen detection, disease resistance, pathogen ecology, and development of disease management systems. His research has involved fungi, bacteria, nematodes, and viruses on agronomic, forage, and vegetable crops, with emphasis on legumes. He has taught a course on introductory plant pathology and a graduate summer field course. He has served on APS committees, was an associate editor for Plant Disease from 1984 to 1986,
twice has served as president of the North Central Division of APS, and is an APS fellow.
Mark E. Hilf is a research plant pathologist at the USDA, ARS U.S. Horticultural Research Laboratory (USHRL) in Fort Pierce, FL. He received a B.S. degree in genetics from the University of California at Berkeley, an M.S. degree in plant pathology from the University of Georgia at Athens, and a Ph.D. degree in plant pathology from the University of California at Riverside. His graduate work examined genetic determinants of host range in tobamoviruses. He began studies on citrus pathogens as a post-doctoral associate when the USHRL was based in Orlando, FL, and joined the staff as a research plant pathologist when the station moved to its present location in Fort Pierce. His research focuses on graft-transmissible diseases of citrus, primarily virus and viruslike pathogens, including research on genetic variability, screening for resistance in citrus cultivars, vector transmission, and etiology. Prior to joining Plant Disease as a senior editor, he served on the APS Virology Committee and also as chief editor for the Proceedings of the 16th Conference of the International Organization of Citrus Virologists (IOCV). Currently, he is chief editor for the proceedings from the 17th IOCV conference.
Debra Ann Inglis, senior editor, is just completing her appointment as interim director/assistant dean for Washington State University’s (WSU) Northwestern Washington Research & Extension Center near Mount Vernon, WA, where she oversaw the recent vitalization of the60-year-old center. Completion of a new $8-million Agricultural Research and Technology building, a successful $2.25-million capital campaign, and significant increases in new programs and faculty recruitment were hallmarks of her efforts, along with those of WSU and numerous community partners. Inglis was a Ph.D. graduate student of R. James Cook when he chaired the APS Committee in 1978 to redesign Plant Disease Reporter and created the foundation of today’s successful Plant Disease format. Inglis, a vegetable pathologist, published her first paper in the first edition of Plant Disease in January 1980. n

Public Policy Board Welcomes Second Early Career Intern, Angela Records
The APS Public Policy Board (PPB) welcomes Angela Records, a Ph.D. student in the Department of Plant Pathology & Microbiology at Texas A&M University (TAMU), as the second PPB early career intern. A native of Texas who grew up in Las Vegas, NV,
Records did her undergraduate work in biology at Baylor University and her M.S. work in biological sciences with James Alfano at the University of Nevada, Las Vegas. At TAMU, she is working in the laboratory of Dennis Gross. In addition, she is a member of the TAMU Graduate Women in Science, serves as president of the Plant Pathology Graduate Student Association, is a mentor in the Aggie Women in Leadership, and was an invited participant in the Aggie Leadership Conference.
Records has been a member of APS since 2003, serving on the APS Bacteriology Committee, the APS Foundation (ex officio), and the APS Graduate Student Committee (chairing the latter in 2005–2006). She has been awarded the APS Council Award (2007), the APS I.E. Melhus Award (2006), and the TAMU Plant Pathology Graduate Student Excellence Award (2005). She also is a member of the American Society for Microbiology.
Because of her interest in working with students, our newest PPB intern aspires to be a university faculty member—but one with a voice in public policy. Issues of climate change and global warming have captured Records’ interest, and she hopes to be in a professional position in which she can become involved in developing reasonable policies to manage such issues. During her internship experience, Records will focus on PPB priority initiatives in microbial genomics and plant pathology education; lessons learned and experience on the board will be applicable in her later efforts related to the environment. Records’ goal was well-articulated in her application letter: “I would like to better understand the legislative system so that I may one day serve as a liaison between scientists and lawmakers.” During the coming year, Records will join the monthly PPB conference calls and participate in the annual spring meeting trip to Washington, DC, where she will assist the PPB in bringing issues of high APS priority to the attention of federal agency administrators and congressional staff. n

The 85th meeting of the APS Southern Division was held February 3–4, 2008, at the Adam’s Mark Hotel in Dallas, TX, in conjunction with the 105th meeting of the Southern Association of Agricultural Scientists. The meeting was hosted by the Plant Pathology and Microbiology Department, Texas A&M University, with Tom Isakeit and Kevin Ong coordinating local arrangements. President Chris Clark welcomed the group to Dallas. Fifty-one registered participants were present and contributed 31 presentations.
President-Elect Kenny Seebold presided over the opening symposium entitled “Extension and Research in the 21st Century—Modern Approaches to New Challenges.” Invited speakers included Paul Vincelli, University of Kentucky; Guido Schnabel, Clemson University; David Langston, University of Georgia; and Karl Steddom, Texas A&M University. Each speaker made an excellent presentation on the integration of research and extension in their respective programs.
The symposium was followed by a graduate student paper competition, presided over by Past President Craig Rothrock. As in previous years, the competition was distinguished by the high quality of the students’ presentations and the excellence of their research. A total of 13 papers was presented by students from Auburn University, Louisiana State University, North Carolina State University, Texas A&M University, the University of Georgia, and the University of Tennessee. After the competition, which spanned 2 days, students and their advisors, invited speakers, Southern Division officers, and APS President Ray Martyn attended a luncheon held in honor of the graduate students. The first place winner ($300 prize) was Jim Kerns (North Carolina State University; advisor, Lane Tredway)

for the paper “Determination of the optimal temperature for infection of creeping bentgrass roots by Pythium volutum.” The second place winner ($200 prize) was Brooke Edmunds (North Carolina State University; advisor, Gerald Holmes) for the paper “Relationships between preharvest conditions and increased susceptibility of sweetpotatoes to Rhizopus soft rot and bacterial soft rot in Louisiana and North Carolina.” The third place winner ($100 prize) was Cruz Torres (Texas A&M University; advisor, David Appel) for the paper “Isolation of Xylella fastidiosa from seven grape varieties in a Texas vineyard.” Rothrock served as chair of the Graduate Student Awards Committee and was assisted by Boyd Padgett, Seebold, and Jason Woodward in judging presentations.
Martyn addressed the group at the business meeting and discussed the range of activities and initiatives being undertaken by APS. Isakeit provided the group with an up-to-date accounting of the Southern Division’s membership and financial status. Tim Brenneman, professor in the Department of Plant Pathology at the University of Georgia, was presented the Outstanding Plant Pathologist Award by Vice President Bob Kemerait in recognition of his nationally recognized research and extension efforts on diseases of peanut and pecans. Kemerait presented travel awards of $300 to Dina Gutierrez, Louisiana State University; S.-Y. Park, Texas A&M University; Ryan Donahoo, University of Tennessee; Edmunds, North Carolina University; and Torres, Texas A&M University.
The program concluded with a social and banquet supported by BASF, Bayer CropScience, Chemtura, United Phosphorus, and Valent U.S.A. Corp. A wonderful evening was enjoyed by the guests, culminating in the
Southern Division DeBary Bowl hosted by the inimitable John Damicone. A team led by Martyn destroyed all challengers, who stood powerless before the breadth and depth of plant pathological prowess demonstrated by the evening’s champions.
Outgoing President Clark “handed over the reins” to incoming President Seebold, who then presented Past President Clark with a plaque in honor of his service and dedication to the APS Southern Division. The meeting was adjourned

Audience Response “Clickers” Debut at 2008 GCSAA SeminarAt the recent 2008 Golf Course Superintendents Association of America (GCSAA) educational seminars in Orlando, FL, APS members John Kaminski (University of Connecticut) and Mike Fidanza (Pennsylvania State University) conducted a half-day seminar called “Maximizing Turfgrass Disease Control with Proper Application Strategies.” A unique feature with this seminar was the first-time use of an audience response system. Seminar attendees were given a hand-held, battery-powered device or “clicker” similar to a TV remote control. Each individual person used their own remote device to answer multiple-choice questions posted throughout the seminar, and the audience answers were immediately summarized and shown on the projection screen for all to see. The audience responses’ provided an opportunity to foster further discussion on several topics covered in the seminar. This seminar served as a pilot program to assess the feasibility of using this type of technology for future GCSAA-sponsored educational seminars and programs. n

Public Policy UpdateNational Plant Diagnostic Network Five-Year Review: Report of the Review PanelDouglas G. Luster, NPDN Review Panel Chair, USDA-ARS, [email protected]
What is the NPDN?The National Plant Diagnostic Network (NPDN) was established by the U.S. Department of Agriculture, Cooperative State Research Education and Extension Service (USDA CSREES) from federal funds in 2002 to fill a major gap in timely, effective, and state-of-the art diagnostic capability for threatening and emerging diseases of concern to the nation’s agricultural system. Initial efforts were focused upon establishing five regional hub labs at land-grant universities (LGUs) representing the Northeast, Western, Southern, Great Plains, and North Central regions, which were conceived to address differences in agricultural production systems in the respective regions. The network has rapidly expanded since 2002 to encompass diagnostic clinics at LGUs in all 50 states and Puerto Rico, with partner clinics in two U.S. territories.
The mission of the NPDN is centered upon national agricultural security, being charged with rapid detection, diagnosis, and early communication of outbreaks of high-priority plant pathogens. The network coordinates and communicates with county and state extension agents, state departments of agriculture, and the USDA, Animal and Plant Health Inspection Service, Plant Protection and Quarantine (USDA APHIS PPQ) during outbreaks in implementing its mission. Training of first responders and diagnosticians is an essential component of the NPDN, ensuring that the network is prepared for the scope of its mission in the event of an outbreak.
In January 2007, the NPDN Executive Committee convened a review panel, consisting of professional representatives from major stakeholders and partners of the NPDN, to conduct a critical review of all facets of the NPDN. The Review Panel met and communicated with NPDN representatives, partners, and stakeholders and developed a report that addresses the NPDN mission, scope, accomplishments, and challenges. The report also provides specific recommendations for future improvement of the network. A condensed version of the Executive Summary of the NPDN Five-Year Review Report is
presented here for the APS membership. The full Executive Summary is available at www.npdn.org/Library/ViewDocument.pdf?filetype= pdf&DocumentId=6430. Comments and questions should be directed to Panel Chair Douglas Luster. The review team believes that the continued development of the NPDN is crucial for the U.S. food and agricultural enterprise.
DiagnosticsThe NPDN has brought a renewed emphasis to, and enhancement of, diagnostics at LGUs and has started to provide an infrastructure for the rebuilding of the linkages between the diagnostic laboratories and extension, regulatory agencies, and the broader community of agricultural practitioners. As a result, the NPDN has significantly contributed to the detection and diagnosis for several recent APHIS-listed “select agent” and high-profile pathogen introductions, resulting in the protection of U.S. agricultural systems and in the reduction of damage to producers and natural ecosystems at the national level.
Challenges remain in the development and application of accreditation standards for diagnostic labs to ensure recognition and acceptance of data by states, regulatory agencies, and partners. This issue is being actively addressed by the NPDN leadership and diagnosticians, who are working together with USDA APHIS and USDA CSREES toward a National Plant Protection Laboratory Accreditation Program. The NPDN is still developing procedures for the event of a national-scale outbreak and associated sample surge. The panel made appropriate recommendations to deal with these issues of workload and surge capacity.
Education and TrainingA vast network of first responders has been developed and is rapidly expanding down to the local level, fulfilling one of the primary visions of the network. Training is a primary focus of the network and is accomplished at the national, regional, and state level with effectiveness, applying a “train-the-trainer” philosophy. Online scenario-based training has been implemented with online access, and standard operating procedures are in place on the Internet for open access.
Information TechnologyThe NPDN has achieved one of the primary
goals of the program in the creation and implementation of a national diagnostic database. The national database promises to be an important tool in rapid response. Significant challenges continue to face the network in developing the NPDN national plant pathogen and pest databases into a robust national plant health database system capable of recording surveillance, detection, and diagnostic information and of delivering appropriate information to agencies and partners for use in rapid response to, and recovery from, harmful pathogen and pest introductions. The review team recommended a full-time chief information officer to coordinate information technology at the national and regional levels. Data access issues need to be clarified, as well as uniformity of reporting of findings to appropriate authorities.
Governance and FundingAn effective governance and operational structure is in place at the regional and national levels. Competent, energetic regional coordinators have developed a true spirit of “teamwork” both within and across the regions and are also working toward improving working relationships with respective state departments of agriculture and appropriate USDA personnel.
The review panel strongly recommended the establishment of a broad-based NPDN Advisory Council at both the national and regional levels to include representatives from the private sector, state/county extension, experiment station/research faculty, certified crop advisors (CCAs), state/federal regulatory agencies, and National Plant Board affiliates. An Advisory Council representative of the members, stakeholders, and partners will help the network to address challenges in surge capacity, information sharing, resource management, and strategic planning for the future structure, operations, and funding.
PartnershipsEffective and complex partnerships are estab-lished and illustrate how far the network has progressed. The NPDN has profited from a commitment to forging strong partnerships and providing training for CCAs, pest control advisors, county extension staff, and other first responders. Most prominently, a solid founda-tion for operating NPDN partnerships exists with the Integrated Pest Management Center Network, with which the NPDN has formed formal partnerships in several regions. The suc-
Phytopathology News 47
cesses of the Soybean Rust Information System, developed in partnerships with the USDA, state departments of agriculture, industry partners, and LGUs, has been expanded in the devel-opment of the Integrated Pest Management Pest Information Platform for Extension and Education, a sentinel system and data manage-ment/decision tool that will serve as a model for partnership between the NPDN and most, if not all, interested federal, state, and private interests.
Recent “select agent” incidents, such as the arrival of soybean rust and Ralstonia solanacearum, have provided an opportunity for extension personnel, CCAs, state regulators, and diagnostic clinicians to exercise incident com-mand system maneuvers and challenge existing communication and diagnostic systems. The need to develop surge capacity for soybean rust, R. solanacearum, and Phytophthora ramorum has encouraged critical working relationships between scientists and administration with the diagnostic labs, state plant health direc-tors, state plant regulatory officials, and APHIS PPQ (Center for Plant Health Science and Technology and Plant Pest Diagnostics Service units). However, a greater level of ongoing interaction and communication is necessary to tighten the safeguarding safety net and assure that responses are rapid and accurate. The diagnostic/education/regulatory partnership recognizes the importance of business confiden-tiality, diagnostic challenges, and the need to minimize potential threats through quarantines and other restrictions. The standing partnerships of the NPDN could become more effective by including an industry component.
Public Relations and OutreachThe NPDN has engaged in structured public relations efforts since its inception and has es-tablished an active Public Relations Committee. Efforts have included the development of a variety of promotional print and electronic ma-terials, highlighting national and regional activi-ties, laboratory capacity, and disease-specific information. National and regional newsletters, brochures, and websites have been effectively deployed to distribute information. The NPDN websites provide quality information on new disease issues and outbreaks in a user-friendly interface (www.NPDN.org). State, regional, and national NPDN members still need to identify and engage new audiences, while sustaining the interest of existing partners and stakeholders.
A top priority must be to further educate com-modity groups, private industry, and other plant industry stakeholders on the mission, scope, and activities of the NPDN and to engage them as partners.
Integration with ResearchThe role of the NPDN is not to conduct research, per se. However, consistent with the land-grant mission of translating research to practice and of providing feedback from stakeholders to the research enterprise, the NPDN is poised to play a central role in defining data gaps and prioritizing research needs to fill those gaps. For example, the NPDN has developed formal relationships with Integrated Pest Management Pest Information Platform for Extension and Education (IPM-PIPE) for analysis of NPDN diagnostic data on soybean rust and the soybean aphid. These relationships serve as outstanding models for the relationship between diagnostics and research.
Pathway to Future SuccessThe review team was very favorably impressed with the progress made in all facets of the NPDN’s national, regional, and state infrastructure, human resources, and technology in the short span of 5 years, with a relatively modest national budget. The NPDN is still in its infancy and has much to do before becoming a fully mature, functioning distributed system of accredited laboratories.
The NPDN benefits as a network largely because of the dedication and efforts of the NPDN leadership and because the diagnosticians at the core of the network actively participate, contribute, and feed back their ideas and vision to the leadership. This was particularly evident at the Five-Year Review Meeting in Orlando, FL, in January 2007, where members, partners, and federal agency representatives held an open discussion on all of the opportunities and challenges ahead. (See www.plantmanagementnetwork.org/proceedings/npdn/2007/) Much of the output from that meeting serves as the core of this review document and should serve as the basis for future development and refinement of the network and its associated systems, partnerships, and structure. n

In Memory
Donald J. Hagedorn, age 87, passed away on April 11, 2007. Don was born in Moscow, ID, on May 18, 1919. He completed his B.S. degree at the University of Idaho (1941) and his M.S. (1943) and Ph.D. degrees (1948) at the University of Wisconsin (UW),
Madison. Don joined the UW-Madison faculty in 1948 as an assistant professor with a joint appointment in the Departments of Agronomy and Plant Pathology. He was promoted to associate professor in 1954 and professor in 1958. In 1964, he received a 100% appointment in the Department of Plant Pathology with focus on pea and bean pathology. He retired in 1987.
Don had a distinguished career as a vegetable pathologist and breeder. He was known internationally for his fundamental studies on virus and root diseases of peas and beans and for the development of pea and bean germplasm resistant to multiple diseases. Together with L. Bos of the Netherlands and L. Quantz of Germany, he organized the National Pea Improvement Association (1957) and the International Working Group of Legume Viruses (1960). He was appointed to the U.S. Plant Variety Protection Board in 1978 by Secretary of Agriculture Robert Bergland. Among his accomplishments were releases of three pea varieties and 14 pea breeding lines with various combinations of new and unique resistances to multiple diseases. His research led to the development of the first processing beans resistant to both races of the halo blight pathogen and the first bean breeding line resistant to the economically important bacterial brown spot disease. In cooperation with Robert Rand, he developed 16 snap bean lines and two red kidney bean cultivars with multiple disease resistances.
During his career, Don published 320 scientific papers, many of which he presented at meetings and conferences throughout the world. Don served as a consultant in Brazil and India and was the first U.S. plant scientist to lecture to the faculty of the University of Prishtina, Yugoslavia. He published the Handbook of Pea Diseases and the Handbook of Bean Diseases. Both publications continue to be used extensively by the vegetable processing industry. Thirty-three graduate students received their Ph.D. degrees and 15 students received their M.S. degrees under his direction, including many international students.
Don received numerous honors, including the Fellow and the Ciba-Geigy Awards from
The American Phytopathological Society, the Campbell Award from the American Association for the Advancement of Science, Meritorious Service Awards from the National Pea Improvement Association and the Bean Improvement Cooperative, the University of Idaho Hall of Fame, an Honorary Doctor of Science Degree from the University of Idaho, the Forty-Niner Service Award from the Food Processing Industry, and the Distinguished Service Citation from the Wisconsin Academy of Sciences, Arts and Letters. He also was accorded sabbatical and study leaves from the UW-Madison to the Institute for Phytopathology in the Netherlands, the University of Rio Grande de Sul in Brazil, Oregon State University, and Lincoln Agricultural Research Center in New Zealand.
Don served his fellow man through work with the Boy Scouts of America and local charitable and religious organizations. He was an avid fisherman, fishing the lakes and streams of Canada, Alaska, Idaho, Montana, and Wisconsin. Don will be remembered by many for his devotion to his wife and family, his sense of humor, his scientific accomplishments, and his great love for all people. He is survived by his wife of 63 years, Eloise; daughter-in-law Orlene; and three granddaughters, Kristen (Brian Katulis), Erin (Andrew Graham), and Sarah.
Robert (Bob) E. Baldwin of Belle Haven, VA, passed away on February 6, 2008, at the age of 76. Born in Emsworth, PA, he graduated from Waynesburg College in 1952 and earned his masters and doctorate degrees after pursuing a course of study in plant pathology
from the University of West Virginia. In 1963, he accepted a position as plant pathologist at
Donald J. Hagedorn
the Virginia Truck and Ornamental Research Station in Painter, VA. While at the research station, Bob conducted extensive field research on the bacterial, fungal, and nematode problems occurring on local agronomic crops, which included potatoes, tomatoes, peppers, snap beans, cucurbits, soybeans, wheat, and on occasion, even herbs and marigolds. Results from these studies were communicated via field days at the research station, extensions meetings throughout Virginia, and in Fungicide and Nematicide Tests. Bob was appointed scientist in charge in 1981. In 1985, he coordinated the transfer of the station to Virginia Tech, at which time he was named director of the Eastern Shore Agricultural Research and Extension Center. He remained director until his retirement in 1996. Bob contributed annually to the Commercial Vegetable Production Guides written and distributed in cooperation with scientists from Delaware, Maryland, Pennsylvania, and New Jersey and never missed the annual meeting of the NJ-Delmarva-PA Plant Pathologists. In 1988 and 1989 on a grant funded by CARDI, Bob traveled to the British West Indies to help potato growers learn to identify and manage yield-limiting diseases on potato in these locales. Bob had a love of roses and ornamentals, with a rose garden of more than 100 varieties. Local ornamental nurserymen on the Eastern Shore frequently called on his experience to diagnose their disease problems even after he retired. He also had a love of fishing, hunting, woodworking, and photography. Bob had a big presence, was good natured, was quick witted, and always had something to say. He had many a humorous story to tell of some of the ridiculous and unexpected situations that often occur out in the field in agriculture. He is survived by his wife, Jacqueline Baldwin; daughter Lauralee Goldstein and husband Billy; daughter Roberta Webb and husband Scott; grandsons Zachary and Luke; and grand dogs Shilow, Shadow, and Sable. Memorial donations may be made to the Shore Cancer Center, 10085 William F. Bernart Circle, Nassawadox, VA 23413 U.S.A. The family may be reached at P.O. Box 241, Belle Haven, VA 23306 U.S.A. n
