Attention: Mr. Reuben Baris (7505P) Product Manager, Team 25

Subject: Requ est for Voluntary Cancellation u nder FIFRA 6(f) of Alachlor Registrations

Dear M r. Baris
, With this letter, Monsanto is hereby requesting volu ntary cancellation of alachlor under FIFRA Section 6(f) without prejudice to future regulatory filings or registration requests. According to our records, Monsanto is the only registrant of this active ingredient.
Appendix I to this letter contains a list of Monsanto’s active regi st rations, including distributor supplemental registrations that include alachlor
, which are subject to this voluntary cancellation request

.
Most i mportantl y, Monsanto stands by the safe use of all our products, including our alachlor

- based herbicides

. Thus we want to emphasize, that t his voluntary cancellation request is based simply on changes in Monsa nto’s commercial business plans and assessment of the marketplace in the U nited States. Despite the long history of the s afe use of alachlor

- based products and their benefit s for effective weed control, the de mand by U.S. farmers for these products has been steadily decreasing ove r the past several years. Monsanto is no longer producing or market ing in the U.S. any of the alachlor

- containing end

- use registra tions listed in Appendix I

. Given this, Monsanto no longer wishes to support the registration of alachlor or to support it in the upcoming Registration Review process.

In mid

- 201 4 , Monsanto initiated U.S. state discontinuance of our alachlor end

- use products. The last time Monsanto produced any alachlor end

- use products for the U.S. market was 2013, and we are work ing to deplete our current inventories

. To facilitate this process we are request ing that the Agency grant 12

mo nths from the date of the final cancellation order to allow for sale of existing stocks of the end

- use product registrations listed in Appendix I.

In addition, Monsanto wishes to waive the 180

- day comment period associated with the publication of this request in the Federal Register to a 30

- day comment period.
Also, given that alachlor is registered in a number of count ries outside the United Stat es, Monsanto is

r equesting
, following the date of the final cancellation order
, that t he current t olerances at 40 CFROctober 13, 2015 Voluntary Cancellation Request

– Alachlor Registrations Page 2 of 3

180.249 remain in the regulations to cover potential residues in treated commodities that may be imported into the U.S.

On a final relate d note, we want the Agency to be aw are that Monsanto will continue to manufacture alachlor and a number of alachlor

- containing end

- use formulations at our production facility in Muscatine, Iowa, for export only to customers outside the U.S., in accordance with FIFRA section 17.
