EPA Pesticide Program Updates: January 22, 2002

IN THIS UPDATE:

• Cancellation and Use Modifications Proposed for Dimethoate
• Disulfoton and Naled Cancellations and Use Deletions Proposed
• Consumer Pesticide Hotline Changes Name; Service Continues

Cancellation and Use Modifications Proposed for Dimethoate

The residential uses proposed for cancellation are any use in or around a structure used as a residence or domestic dwelling or on any article or areas associatedwith such structures (e.g., home gardens) and any use in public or private buildings or structures (including recreational facilities, theaters, etc.) or articles or areas associated with such structures (e.g., landscaping and playgrounds).

Agricultural uses proposed for cancellation are housefly treatments on farm buildings and structures, farm animal quarters, and manure piles. Dimethoate is a systemic organophosphate insecticide primarily used on a variety of field and orchard agricultural crops, and ornamentals.

EPA intends to grant the requested cancellations and amendments to delete uses and will issue a cancellation order for the deleted uses and the canceled registrations at the close of the comment period. The cancellation order will specify conditions for sale and use of the products after issuance of the order. EPA anticipates that the cancellation order would allow for 1-year use of existing stocks after the effective date of the amendment or cancellation order. EPA must receive comments on this proposal on or before February 11, 2002, identified by docket control number OPP-34143C.

The Federal Register notice providing details on this proposal is on EPA's web site. Information on EPA's review of the pesticide dimethoate is also available on the web. The Agency recognizes that dimethoate use on outdoor commercial ornamental tree, shrub and annual plant production areas is being supported by the technical registrants. While use on ornamentals in other settings is no longer being supported, outdoor commercial ornamental production areas may remain on dimethoate labels.

Disulfoton and Naled Cancellations and Use Deletions Proposed

Disulfoton is an insecticide and acaricide primarily used on a variety of field grown agricultural crops, ornamentals, and Christmas trees. Bayer Corporation has proposed to delete certain crop uses from its disulfoton product labels, including dry beans, peas and lentils, poplars grown for pulpwood, sorghum, soybeans, tobacco, and triticale. Value Garden Supply, LLC wishes to voluntarily cancel two lawn and garden products containing disulfoton.

Naled, also an insecticide and acaricide, is used primarily to control mosquitoes. Sergeant's Pet Products, Inc. has proposed to voluntarily cancel four flea and tick pet collar products containing naled.

Comments on the requested disulfoton and naled cancellations and use deletions must be submitted to EPA within 30 days of the FR notice, or by February 11, 2002. Unless meritorious comments opposing them are received, EPA intends to grant the requests for voluntary cancellations and use deletions. Registrants will be allowed to sell existing stocks of affected disulfoton products for 12 months after the effective date of cancellation. The naled registrant has requested that March 1, 2002, be the effective date of cancellation, and that sale and distribution of existing stocks be allowed until December 31, 2002. The Agency plans to grant that request, and plans to allow people other than registrants to sell, distribute, or use disulfoton and naled products until supplies are exhausted. EPA's Federal Register notice is available on the Agency's web site.
