FIDLs: Pathogens by Scientific Name
note: If a FIDL covers >1 organism, then it will be listed for each organism (up to 5 per FIDL); if the scientific name has changed, the FIDL will be listed for both the current name and the original name (for first organism listed if >1). Please
contact the FIDL coordinator if you think a scientific name
listed here is erroneous.
Caveat: Management strategies and tactics discussed in older leaflets may be outdated. Contact your nearest USFS Forest Health Protection Office or your state's Department of Forestry or Natural Resources for current information.
