Small Fruit Pathology Team Washington State University
WSU’s small fruit pathology research program is focused on the biology, epidemiology and control of diseases affecting small fruit (berries) in the Pacific Northwest. Current research efforts are focused on the biology and epidemiology of Botrytis cinerea infecting raspberry and blueberry, population and evolutionary biology of fungicide resistance in B. cinerea infecting berry crops and the epidemiology of mummyberry of blueberry caused by Monilinia vaccinii-corymbosi. The long-term objectives of the research program are to use knowledge of the basic biology of berry pathogens and their life cycles to improve disease control and sustainability. Other research interests include the role of host specificity in fungal speciation and speciation processes in asexual fungi using Ascochyta and Alternaria fungi as model systems. Recent projects in the lab include the molecular epidemiology of eucalypt rust in Brazil, the systematics, ecology and evolution of Morchella spp. (black morels) in the Pacific Northwest and the evolution of Alternaria spp. infecting wild and cultivated pistachios in Turkey.
Dalphy started her postdoc at WSU Mount Vernon Research Center in September 2014, which focuses on the biology and epidemiology of mummyberry disease of blueberries. She was born and raised in Nieuwenhoorn, a small town in the Netherlands. She did undergraduate degree in Biology and Medical Sciences at Rotterdam University, Rotterdam, the Netherlands. For the final thesis of the Bachelor degree she did an internship at the University of Queensland (UQ) in Brisbane, Australia, working on Fusarium wilt of banana. There, she found her passion for plant pathology. She graduated in 2008, went back to Australia and worked as a technician for the Qld Agricultural Department and UQ Tree Pathology Group, developing a broad range of skills working with viruses, bacteria and fungi on fruit and nut trees and vegetables. In 2010 she started her PhD at the University of Queensland, which aimed to determine the etiology of Alternaria diseases of apples in Australia. She received her PhD degree in plant pathology in May 2014.
Olga moved to the USA from Ukraine, where she received her Master degree in plant biotechnology from the National University of Life and Environmental Sciences of Ukraine. During her master’s program Olga worked with six novel canola cultivars studying their prospective ability of morphogenesis, rizogenesis and genetic transformation in vitro. Inspired by love for science she decided to expand her borders and continue graduate studies, starting her PhD at the WSU Plant Pathology Department in fall 2014. Olga’s current research is concentrated on studying biology, ecology and population genetics of the plant pathogen Botrytis cinerea on red raspberry in Pacific Northwest.
Dave grew up in north-central Kansas and received his BS degree in chemistry and biology from Fort Hays State University. He has worked at WSU in biology, chemistry and molecular biology labs for 26 years and now runs the Botrytis cinerea fungicide resistance screening program from the lab in Pullman. Dave is responsible for development and implementation of fungicide resistance assays and assisting other berry pathology research personnel with various aspects of their research.

Jay W. Pscheidt received his Ph.D. in Plant Pathology from the University of Wisconsin-Madisonin 1985. Since 1988 he has been a professor at Oregon State University as an Extension PlantPathology Specialist. His principal duties are to lead a statewide extension program related to thediagnosis and management of diseases of all fruit, nut, and ornamental/nursery crops. He is also coeditor of regional publication The Pacific Northwest Plant Disease Management Handbook.
