Cassandra Swett

Cassandra Swett is an Associate Professor in Cooperative Extension at the University of California, Davis. Her research focuses on fungal pathogen ecology in vegetables and field crops, particularly investigating how adaptive water use strategies impact plant-pathogen interactions. She examines the effects of deficit irrigation, soil salinity, and water recycling on disease dynamics in crops such as tomatoes, hemp, strawberries, and nursery plants. Her work bridges fundamental microbial ecology with applied agricultural solutions to address challenges posed by water scarcity and climate change.

Key research areas include: (1) managing Fusarium wilt and root-knot nematode complexes in tomatoes under water-stressed conditions, (2) optimizing irrigation practices to reduce soil-borne disease risks in nursery crops, and (3) identifying resistance-breaking pathogen strains threatening California agriculture. Swett collaborates closely with growers to translate scientific findings into practical management strategies.

Her lab (http://swettlab.faculty.ucdavis.edu/) develops disease forecasting tools, evaluates water conservation techniques, and explores symbiotic microbial interactions that enhance crop resilience. She emphasizes co-management approaches that balance disease control with sustainable resource use.
