of the technical active ingredient Phosmet, has requested to amend its
registrations of Imidan Technical (EPA reg. no. 10182-234) Imidan 50-WP
(EPA reg. no. 10182-173] and Imidan 70-WP (EPA reg. no. 10182-224) by

SUPPLEMENTARY INFORMATION:  Phosmet is the commonly accepted name for
(mercaptomethyl) phthalimide S-(O,O-dimethylphosphorodithioate). It is a
broad spectrum organophosphate insecticide/acaricide which was initially
registered as a pesticide under FIFRA in 1966 by Stauffer Chemical
Company. Phosmet is available as a 90 percent and 94 percent active
ingredient technical product for formulating phosmet end use products.
Technical phosmet is produced by ICI Americas under the trade name
Imidan Technical (90 percent) and Prolate Technical (94 percent).
Phosmet is primarily used in the formulation of insecticides/miticides
products for use on crop and non-crop areas. ICI Americas, the sole
registrant of the technical grade of the active ingredient phosmet, has
requested to amend its registration of Imidan Technical, Imidan 50-WP
Agricultural Insecticide, and Imidan 70-WP Agricultural Insecticide by
deleting all uses and directions for use on citrus, grapes, alfalfa,
corn, cotton, peas and potatoes. EPA intends to approve the request.
Since ICI is the sole registrant of the technical grade phosmet there
will no longer be a manufacturing use product available from which to
formulate any registered use products for phosmet on citrus, grapes,
alfalfa, corn, Cotton, peas, and potatoes. End-use registrants are being
notified by certified mail that their generic data exemption will be
revoked and they will be given the opportunity to generate data in
support of these uses.  EPA is now soliciting comments on the proposed
amendments.  Interested persons are invited to submit their written
comments to the address given above.
