ENVIRONMENTAL PROTECTION AGENCY

Ciba-Geigy Corp.; Approval of Pesticide Product Registrations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces Agency approval of applications 
submitted by Ciba-Geigy Corporation, to conditionally register the 
pesticide products Dividend Fungicide and Technical CGA-169374, 
containing a new active ingredient not included in any previously 
registered products pursuant to the provisions of section 3(c)(7)(C) of 
the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as 
amended.

FOR FURTHER INFORMATION CONTACT: By mail: Cynthia Giles-Parker, Product 
Manager (PM) 22, Registration Division (7505C), Office of Pesticide 
Programs, 401 M St., SW., Washington, DC 20460. Office location and 
telephone number: Rm. 229, CM #2, Environmental Protection Agency, 1921 
Jefferson Davis Hwy, Arlington, VA 22202, (703-305-5540).


SUPPLEMENTARY INFORMATION: EPA issued a notice, published in the 
Federal Register of October 21, 1993 (58 FR 54351), which announced 
that Ciba-Geigy Corp., P.O. Box 18300, Greensboro, NC 27419-8300, had 
submitted applications to register the pesticide products Dividend 
Fungicide and Technical CGA-169374 (EPA File Symbols 100-TUN and 100-
TGO) containing the active ingredient difenoconazole [(2S,4R) / 
(2R,4S)] / [2R,4R/2S,4S)] 1-(2-[4-(4-chlorophenoxy)-2-chlorophenyl]-4-
methyl-1,3-dioxolan-2-yl-methyl)-1H-1,2,4-triazole at 32 and 92 percent 
respectively, an active ingredient not included in any previously 
registered products. 
    These applications were approved on August 4, 1994, as Dividend 
Fungicide (EPA Registration Number 100-740) as a seed treatment for 
control of diseases on wheat and Technical CGA-169374 (EPA Registration 
Number 100-739) for formulation into end-use fungicide products.
    A conditional registration may be granted under section 3(c)(7)(C) 
of FIFRA for a new active ingredient where certain data are lacking, on 
condition that such data are received by the end of the conditional 
registration period and do not meet or exceed the risk criteria set 
forth in 40 CFR 154.7; that use of the pesticide during the conditional 
registration period will not cause unreasonable adverse effects on the 
environment; and that use of the pesticide is in the public interest.
    The Agency has considered the available data on the risks 
associated with the proposed use of difenoconazole and information on 
social, economic, and environmental benefits to be derived from such 
use. Specifically, the Agency has considered the nature of the chemical 
and its pattern of use, application methods and rates, and level and 
extent of potential exposure. Based on these reviews, the Agency was 
able to make basic health and safety determinations which show that use 
of difenoconazole during the period of conditional registration is not 
expected to cause any unreasonable adverse effect on the environment, 
and that use of the pesticide is in the public interest.
    Adequate chemistry, toxicological, ecological effects, and 
environmental fate data have been submitted and reviewed to support the 
conditional registration of difenoconazole for use as a seed treatment 
fungicide of wheat. The terms of the conditional registration will 
require Ciba-Geigy to submit Stability of the Technical Grade Active 
Ingredient (TGAI) to Metal Ions Study [Guideline Number 63-13], Storage 
Stability of difenoconazole in other Raw Agricultural Commodities [171-
4(e)], and additional Wheat Field Residue Trials [171-4(k)].
    Consistent with section 3(c)(7)(C), the Agency has determined that 
these conditional registrations are in the public interest. Use of the 
pesticides are of significance to the user community, and appropriate 
labeling, use directions, and other measures have been taken to ensure 
that use of the pesticides will not result in unreasonable adverse 
effects to man and the environment.
    More detailed information on these conditional registrations is 
contained in an EPA Pesticide Fact Sheet on difenoconazole.
    A copy of the fact sheet, which provides a summary description of 
the chemical, use patterns and formulations, science findings, and the 
Agency's regulatory position and rationale, may be obtained from the 
National Technical Information Service (NTIS), 5285 Port Royal Road, 
Springfield, VA 22161.
    In accordance with section 3(c)(2) of FIFRA, a copy of the approved 
label and the list of data references used to support registration are 
available for public inspection in the office of the Product Manager 
listed above. The data and other scientific information used to support 
registration, except for material specifically protected by section 10 
of FIFRA, are available for public inspection in the Public Response 
and Program Resources Branch, Field Operations Division (7506C), Office 
of Pesticide Programs, Environmental Protection Agency, Rm. 1132, CM 
#2, Arlington, VA 22202 (703-305-5805). Requests for data must be made 
in accordance with the provisions of the Freedom of Information Act and 
must be addressed to the Freedom of Information Office (A-101), 401 M 
St., SW., Washington, DC 20460. Such requests should: (1) Identify the 
product name and registration number and (2) specify the data or 
information desired.
