II. Receipt of Request to Cancel Registrations

A. Background

Fenridazone is a dihydro-oxopyridizine pesticide which was registered as a growth regulator used on wheat. The technical registrant, Monsanto Company requested a voluntary cancellation of their registration for the product containing fenridazone potassium.

Pursuant to section 6(f)(1) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA announced receipt of the request from Monsanto Company in a Federal Register Notice published on July 25, 2003 (68 FR 44081) (FRL-7315-6). In that notice, EPA provided a 30-day comment period. The registrant requested the Administrator waive the 180-day comment period provided under FIFRA section 6(f)(1)(c), and EPA granted this request. No public comments were received during the 30-day comment period.

B. Requests for Voluntary Cancellation of Products

III. Cancellation Order

Pursuant to section 6(f)(1)(A) of FIFRA, EPA is approving the requested cancellation. Accordingly, EPA orders that the registration identified in Table 1, is hereby canceled. Any distribution, sale, or use of existing stocks of the product identified in the table above in a manner inconsistent with the terms of this order or the existing stock provisions in Unit IV. of this Federal Register Notice will be considered a violation of section 12(a)(2)(K) of FIFRA and/or section 12(a)(1)(A) of FIFRA.

IV. Existing Stocks Provisions

For purposes of this order, the term “existing stocks” is defined, pursuant to EPA's Existing Stocks Policy (56 FR 29362, June 26, 1991) (FRL-3846-4), as those stocks of a registered pesticide product which are currently in the United States and which have been packaged, labeled, and released for shipment prior to the effective date of cancellation.

V. Distribution or Sale by the Registrant

Cancellation orders generally permit a registrant to sell or distribute existing stocks for 1 year after the date the cancellation request was received. However, the registrant has stated that the Hybrex 2 LC Chemical Hybridizing product has not been sold since 1989 nor has the chemical ever been distributed. Therefore, no products should be in the channels or trade.
