Forest Phytophthoras of the World

This website offers science-based information to aid in the understanding and management of the world’s forest Phytophthora species. Twenty of the most damaging species of forest Phytophthoras are profiled as of January 2021. Click on any Phytophthora species (left sidebar on the database) for information about the pathogen and the forest disease(s) it causes, access educational and disease management materials, and view scientific references.

Identification Technology Program IDTools

IDphy Molecular Protocols 

In order to facilitate the correct identification of Phytophthora species, we provide standards of procedures (SOPs) for all steps involved with molecular identification using sequencing analysis of the ITS rDNA and COI barcoding regions. 

IDphy Morphological Protocols 

In order to facilitate accurate identification of Phytophthora species, we provide standards of procedures (SOPs) for isolation, maintenance, storage of isolates, methods for sporulation, and other tasks related to morphological identification.
