The following lists document additions, modifications and deletions to the National Data Repository (NDR) Host and Pest dictionaries that were implemented in June 2026. You can view updates to the NPDN host and pest dictionaries any time by logging into NDR clicking on the Dictionaries tab, selecting the Change Request tab, and selecting Updates from the dropdown menu.
A guideline to understanding data dictionaries in the NDR is available to NPDN members online. NPDN members also have access to an online guideline on how to request new host/pest codes or changes to existing codes. Members must be logged in to access the NDR and the guidelines.
