Scope of the catalog

This catalog expands on previous work of the Julien Catalog and CABI's "Biocat", including information on host range estimation and literature host records, to give a sense of the likely specificity of each agent. It also includes information on synonyms of the agent's name to aid in understanding the literature. The records were assembled by the first author (RVD) from species-specific literature searches of the CAB abstracting database and other resources.
