All Approval Holder Letters Index

As outlined in All Approval Holder Letter 07/2004 Regulatory Updates replaced all approval holders letters as the means of notifying approval holders and interested parties of changes to application procedures, the approvals process and of changes to legal requirements for Approval Holders.

Before March 2004, PSD sent out letters on important changes in regulation or policy on pesticides to approval holders and other interested parties, and these were called "All Approval Holder Letters".

All letters has been removed from the pesticides web site. However, many of these are still available from the National Archive copy of this page from 2012.

Details of changes to legal requirements, application procedures and the approvals process are now being published as Regulatory Updates.

You can search the following list of current All Approval Holders Letters by year.
