Dear Ms. White:

Re:  Registration of Sanmite 75 WP Miticide/Insecticide (EPA Reg. No.
7969-106) containing the New Active Ingredient Pyridaben

The New York State Department of Environmental Conservation has approved
your application to register the pesticide product Sanmite 75 WP (EPA
Reg. No. 7969-106) containing the new active ingredient pyridaben in New
York State.  Sanmite 75 WP is approved as labelled for use in control of
mites and whiteflies in Greenhouses on ornamental plants, flowers, and
foliage (non-food) crops.

Labelled uses of Sanmite 75 WP should not adversely impact the fish and
wildlife resources of New York State, or pose significant risk to
workers adhering to the personal protective equipment requirements.

While the data was sufficient to approve indoor use of pyridaben, should
BASF Corporation apply for outdoor use of pyridaben, additional data
would be needed to properly assess the risk to the fish and wildlife
resources of New York State.

The following four items must be submitted for any review of pyridaben
for outdoor use:

     * The KoW or log P of pyridaben.
     * The number of repeat applications allowed per season for each
       outdoor use.
     * Chronic rat DER #426801-32.  The DER in the current data package
       is missing all of the even pages.
     * The following studies required by the Division of Fish & Wildlife
       in its Branch Review dated 4/21/94:  acceptable chronic studies
       with freshwater invertebrates and fish species, studies with
       marine/estuarine species, and honeybee studies.  These studies
       were to have been started in April 1994 as a microcosm protocol
       and 6(a)2 data regarding a fish life cycle study has already been
       reviewed by the EPA.

A value of 14 micrograms/liter will be considered the State drinking
water standard for pyridaben.  Pyridaben does not appear to have high
leaching potential in soil and given its use pattern would not be
expected to pose a significant threat of drinking water/groundwater
contamination.

Enclosed for your records are copies of the stamped-accepted label and
the certificate of registration for Sanmite 75 WP (EPA Reg. No. 7969-
106).  If you have any questions on this matter, please contact Maureen
Serafini, Supervisor of our Pesticide Product Registration Section, at
(518) 457-7446.

Sincerely,

Norman H. Nosenchuck, P.E.
