Research Interests

Our research and extension program aims to develop integrated management strategies for current and emerging potato and sugar beet diseases. Current investigations of pathogen biology, ecology, and disease epidemiology help us develop tools, including predictive models and remote sensing technologies, for use in effective and economical disease management.
