SPRO letters are official communication from the APHIS PPQ Deputy Administrator advising State Plant Regulatory Officials of significant and timely changes to phytosanitary regulations or emerging phytosanitary issues. Despite our best efforts, this collection of SPRO letters may not be complete and topical concerns should be addressed through your APHIS PPQ State Plant Health Director
(click on the state you are interested in once the APHIS web page loads). If you have a SPRO letter not listed below, please forward the document to the webmaster. SPRO letters are posted without editing. More current SPRO letters may supercede previous postings.
