Cancellation of Certain Agricultural Uses of Diazinon

January 2007

Registration Amendments Completed

On January 9, 2007, EPA mailed letters to diazinon registrants amending their registrations by cancelling certain agricultural uses. These uses, outlined for cancellation as part of the mitigation in the September 2002 Diazinon Interim Reregistration Eligibility Decision (IRED), include the following:

For granular products

For liquid and wettable powder products

No Comments Received on Use Deletions

The cancellation letters followed EPA's December 6, 2006 Federal Register Notice announcing receipt of requests by registrants to amend their diazinon registrations. All diazinon registrants waived the 180-day comment period in favor of a 30-day comment period. The Agency did not receive comments on any of these use deletions.

Few Remaining Agricultural Uses

All residential uses of diazinon were cancelled as of December 31, 2004. The only remaining uses are agricultural uses on a variety of fruit, vegetable, nut, and field crops, as well as use on non-lactating cattle as an ear-tag.
