Mary Powelson and Debra Inglis
 |
Mary Powelson is professor of plant pathology at Oregon State University. Her research interests focus on the integration of cultural and chemical tactics to control both single and multiple diseases of potatoes and vegetables. Current potato research projects emphasize the effects of water deficit stress on the biology of vascular wilt diseases, integration of green manures into cropping systems to suppress diseases caused by root-infecting pathogens, and evaluation of target and nontarget potato seed piece treatments on transmission of the late blight pathogen from the seed tuber to the developing sprout. Her teaching responsibilities include an introductory course in plant pathology for undergraduate students and participation in a team-taught graduate course on plant disease management. Debra Inglis (Washington State University) and she are coordinators of a North American trial on efficacy of registered and Section 18 fungicides for control of late blight and are developing a web site on late blight of potato with growers and extension personnel as the target audience.
Mary is a member of the American Phytopathological Society of America and the Potato Association of America. She served as Pacific Division Councilor and Councilor-at-Large of APS and completed a term as Senior Editor of Phytopathology. Currently, she is a member of the Executive committee and the Editorial board of the PAA. |

Debra Ann Inglis is a research and extension vegetable plant pathologist at the Washington State University-Mount Vernon Research and Extension Unit. She earned M.S. and Ph.D. degrees in plant pathology from Washington State University in 1976 and 1982, respectively, and completed postdoctoral work at the University of Wisconsin in 1984. From 1984 to 1986 she worked as a Small Grains Integrated Pest Management specialist for the Montana State University Cooperative Extension Service. Since 1990, she has worked in the vegetable pathology program at WSU-Mount Vernon, becoming program leader in 1993. Here research and extension duties include the biology and control of fresh and processing vegetables and vegetable seed crops in western Washington. She co-authored Diseases of Washington Crops which was published in 1993, and she served as co-coordinator of the National and North American Late Blight Fungicide trials in 1996 and 1997, respectively. This year she serves as director of the pathology division of the Potato Association of America. Currently, she maintains an active research and extension program on potato late blight in western Washington as well as on other vegetable disease problems. |
