SUPPLEMENTARY INFORMATION: EPA issued a notice published in 
the Federal Register of May 29, 1992 (57 FR 22749), which announced 
that Ciba-Geigy Corp., PO Box 18300, Greensboro, NC 27419, had 
submitted an application to register the pesticide product Primo 
(EPA File Symbol 100-TEO) containing 12 percent of the active 
ingredient cimectacarb 4-(cyclopropyl-alpha-hydroxy-methylene)-
3,5-dioxo-cyclohexanecarboxylic acid ethyl ester, an active 
ingredient not included in any previously registered product. 
   EPA also received an application from Ciba-Geigy to register 
the product Cimectacarb Technical (EPA File Symbol 100-TET), 
which was inadvertently omitted from the notice that published 
in the Federal Register of May 29, 1992. The product contains 
92 percent of the same active ingredient as listed above. However, 
since the notice of receipt of application for Cimectacarb Technical 
was not published in the Federal Register, as required by section 
3(c)(4) of FIFRA, as amended, interested parties may submit 
written comments within 30 days from the date of publication 
of this notice for this product only. 
   These applications were approved on February 11, 1993 as 
Primo (EPA Registration Number 100-729) for managing growth, 
--More--(41%)[Press space to continue, 'q' to quit.]improving quality, and 
edging of warm and cool season turfgrasses 
and Cimectacarb Technical (EPA Registration Number 100-727) 
for formulating into end use turf growth regulators intended 
for use in managing growth of warm and cool season turfgrasses. 
   A conditional registration may be granted under section 3(c)(7)(C) 
of FIFRA for a new active ingredient where certain data are 
lacking because a period reasonably sufficient for generation 
of the data has not elapsed since the Administrator first imposed 
the data requirements, 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 cimectacarb 4-(cyclopropyl-
alpha-hydroxy-methylene)-3,5-dioxo-cyclohexanecarboxylic acid 
ethyl ester, 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 
--More--(63%)[Press space to continue, 'q' to quit.]to make basic health and 
safety determinations which show that 
use of cimectacarb 4-(cyclopropyl-alpha-hydroxy-methylene)-3,5-
dioxo-cyclohexanecarboxylic acid ethyl ester 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. 
   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 the EPA Pesticide Fact Sheet, Number 239, for 
cimectacarb 4-(cyclopropyl-alpha-hydroxy-methylene)-3,5-dioxo-
cyclohexanecarboxylic acid ethyl ester. 
   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 
--More--(83%)[Press space to continue, 'q' to quit.]approved label and the 
list of data references used to support 
registration are available for public inspection in the office

used to support registration, except for material specifically
