The 11th I. E. Melhus Graduate Student Symposium was held 9 August 2011 during the joint meeting of the American Phytopathological Society (APS) and the International Plant Protection Conference (IPPC) in Honolulu, HI. The I. E. Melhus Graduate Student Symposium has been held annually since 1999 and remains one of the most prestigious APS Annual Meeting events. This symposium features graduate students who are chosen on a competitive basis to present their thesis research results. The 11th I. E. Melhus Symposium was organized and co-sponsored by the APS Epidemiology Committee. Selection criteria for the 11th I. E. Melhus Graduate Student Symposium included: (i) submission of a 5-page synopsis of the students graduate research project (excluding tables and figures); (ii) an expert panel evaluation of the originality and significance of each applicants research contribution toward improving our understanding of plant disease epidemiology and disease management; (iii) an evaluation of each applicants written communication skills; (iv) two letters of nomination from each applicants institution, (v) active membership in APS; and (vi) the requirement that the participants graduate degree was completed no longer than 12 months before the 2011 APS Annual Meeting. The co-sponsors and organizers of the 11th I. E. Melhus Graduate Student Symposium wish to extend a special thanks to the four APS members who served as judges to select the 2011 symposium participants. The judges were Kira Bowen, David Gent, Peter Ojiambo, and Stephen Wegulo.
The I. E. Melhus Graduate Student Symposium Fund
The Irving E. Melhus Graduate Student Symposium Fund was created in 1999 by the APS Foundation with the goal of enhancing graduate student professionalism, as well as to memorialize an esteemed plant pathologist and educator. The I. E. Melhus Symposium Fund was established in Melhus honor through generous donations provided by Mr. and Mrs. William Paddock, Mr. And Mrs. Walter Goeppinger, and Dr. and Mrs. Jack Wallin. The 11th I. E. Melhus Graduate Student Symposium was sponsored by the APS Epidemiology Committee and the APS Foundation. Each of the four 2011 Melhus awardees received a $1,000 travel award from funds provided by the APS Foundation and private industry sponsors, including Agdia, Inc.; BASF Corporation; E. I. du Pont de Nemours and Company; and Pioneer Hi-Bred International, Inc.
History of the I. E. Melhus Graduate Student Symposium
Every three years from 1984 to present, the APS Epidemiology Committee has sponsored and organized a Graduate Student Symposium to highlight the innovative epidemiological research that is being conducted by graduate student members of APS. In 1999, the APS Foundation approached the APS Epidemiology Committee with a proposal for the Epidemiology Committee to organize the first I. E. Melhus Graduate Student Symposium. The APS Foundation introduced plans to make the I. E. Melhus Graduate Student Symposium an annual event by using the traditional framework developed by the Epidemiology Committee to competitively select student speakers each year. The APS Foundation provides partial travel awards for the four to six graduate student participants who are chosen each year. It was agreed that the APS Epidemiology Committee would continue the tradition of co-sponsoring the I. E. Melhus Graduate Student Symposium on a three-year cycle, with other APS Subject Matter Committees submitting proposals to co-sponsor the event in the two intervening years.
It is appropriate that the APS Epidemiology Committee was asked to co-sponsor and organize the first I. E. Melhus Graduate Student Symposium, as Professor Irving E. Melhus was an early pioneer in the field of plant disease epidemiology and had a major influence on graduate student research and education. Over a period of 30-plus years as a faculty member at Iowa State College (now Iowa State University), Melhus mentored many outstanding graduate students, including L. W. Durrell, who received the first Ph.D. in Plant Pathology from Iowa State College in 1923.
Irving E. Melhus: Historical Perspectives and Accomplishments
Dr. Irving E. Melhus was born on 2 April 1881 at Creston, IL, and grew up in Ellsworth, IA. Dr. Melhus earned a B.Sc. degree in 1906 from Iowa State College and was the first graduate to receive a Ph.D. in Plant Pathology at the University of Wisconsin (1912). Dr. Melhus accepted a appointment in the Office of Vegetable Crop Diseases in the USDA Bureau of Plant Industries to work on potato diseases. In 1916, Dr. Melhus accepted a faculty position in plant pathology at Iowa State College, thereby becoming the first plant pathologist in the Agricultural Experiment Station and Botany Department of Iowa State College. Dr. Melhus was named Head of the Department of Botany, and under his leadership, the department grew and gained national prominence within the Land Grant System. In 1946, Dr. Melhus organized the Iowa State College-Guatemala Tropical Research Center to provide more favorable opportunities for research on corn improvement, which led to substantial increases in corn production in the United States, Guatemala, and Southeast Asia.
I. E. Melhus and his Service to APS
Dr. Melhus joined APS in 1911 and was active in its affairs his entire career, serving as Vice-President in 1911, Councilor-at-Large in 1922 and 1923, and President in 1926. He was elected a Fellow of APS in 1969, the first year that this prestigious recognition was established by the society.
Participants in the 11th I. E. Melhus Graduate Student Symposium (2011)
The APS Epidemiology Committee, in conjunction with the APS Foundation and private industry co-sponsors, congratulate the following four graduate students, who were chosen to participate in the 11th I. E. Melhus Graduate Student Symposium.
Daniel J. Anco completed his Ph.D. in December 2011 under the direction of Lawrence V. Madden and Mike Ellis. Daniel received his B.Sc. from Lewis University in Illinois and his M.Sc. degree from The Ohio State University (OSU) in 2010. His Melhus symposium presentation title was Effects of Temperature and Leaf Wetness Duration on the Sporulation Rate of Phomopsis viticola on Infected Grape Canes. Daniel developed nonlinear regression analyses to choose an appropriate model to describe the effects of leaf wetness, temperature, and seasonality on the sporulation process of Phomopsis viticola. Daniel has been an active member of the APS Epidemiology Committee since 2009. He received the C. C. Allison Award in 2011 for outstanding performance in graduate research and service to the Department of Plant Pathology at OSU.
