Overview
The CDFA Plant Pathology Collections are maintained as several separate entities.
- Phytophthora species isolate collection.
- Herbarium of fungal plant disease specimens from California.
- Isolate collection of fungal plant pathogens found in California.
- Bacterial culture collection (formerly housed at University of California, Berekely).
The collection is used mainly as in-house reference material to assist CDFA scientists in the identification of and research on plant pathogens. No type material is maintained in the collection.
Collections Use Guidelines
Collection material is not available for loan. However, visiting scientists are welcome to examine and work with the specimens in the CDFA Plant Pathology Laboratory, by arrangement.
