Extension
of Tolerances for Emergency Exemptions. FINAL
RULE.
•
Lambda-cyhalothrin.
EPA has authorized under FIFRA section 18 the use of lambda-cyhalothrin
on barley for control of the Russian wheat aphid and cutworms
in Idaho, Colrado, Wyoming and Montana.
This regulation extends time-limited tolerances for combined
residues of the pyrethroid lambda-cyhalothrin in or on barley
grain at 0.05 ppm, barley bran at 0.2 ppm, and barley hay
and straw at 2.0 ppm for an additional
3-year period. These tolerances will expire
and are revoked on December 31, 2008. Time-limited tolerances
were originally published in the Federal
Register of October 29, 1997.
•
Lambda-cyhalothrin.
EPA has authorized under FIFRA section 18 the use of lambda-cyhalothrin
on alfalfa/clover/grass mixed stands for control of potato
leafhoppers in New York. This

of the pyrethroid lambda-cyhalothrin in or on Clover,
forage at 5.0 ppm; Clover, hay at 6.0 ppm; Grass, forage at
5.0 ppm; and Grass, hay at 6.0 ppm for
an additional 3-year period. These tolerances will
expire and are revoked on December 31, 2008. Time-limited
tolerances were originally published in the Federal Registers

Lambda-Cyhalothrin
and Gamma-Cyhalothrin. Tolerances for Residues. FINAL
RULE. EPA is amending 40 CFR part 180 by promulgating
a new tolerance expression for the isomer form of gamma-cyhalothrin.
Gamma-cyhalothrin is the isolated active isomer of lambda-cyhalothrin
under 40 CFR 180.438. Pytech Chemicals
GmbH, 9330 Zionsville Rd., Indianapolis, IN 46268,
requested this change in tolerance expression in support of
the registration of a pesticide formulation enriched with
the gamma isomer of lambda-cyhalothrin.
EPA's previous risk
assessment on lambda-cyhalothrin (September
27, 2002,
Federal Register) is sufficient
to cover gamma-cyhalothrin. Accordingly,
a new aggregate risk assessment for gamma-cyhalothrin is not
needed.
It is noted that in
the developmental toxicity study in the rat that the resolved
gamma
isomer is over an order of magnitude more toxic than in cyhalothrin.

Announcement:
Longitudinal Study of Young Children's Exposures in their
Homes to Selected Pesticides, Phthalates, Brominated Flame
Retardants, and Perfluorinated Chemicals
(A Children's Environmental Exposure Research Study--CHEERS).
Abstract: The U.S. EPA's Office of Research and Development's
National Exposure Research Laboratory proposes to conduct
a two-year longitudinal field measurement study of young children's
(aged 0 to 3 years) potential exposures to current-use pesticides
and selected phthalates, polybrominated diphenyl ethers, and
perfluorinated compounds that may be found in residential
environments. The study will be conducted in Duval County,
Jacksonville, Florida over a two-year period from 2004 to
2006. Sixty young children will be recruited into this study
in two cohorts: (1) infants recruited into the study soon
after birth, and, (2) children recruited into the study at
approximately 12 months of age.

barley for control of the Russian wheat aphid and cutworms
in Idaho, Colrado, Wyoming, and Montana.
This regulation extends a time-limited tolerance for combined
residues of the pyrethroid lambda-cyhalothrin, 1:1 mixture
of (S)-[alpha]-cyano-3- phenoxybenzyl-(Z)-(1R,3R)-3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2-

SYNGENTA.
Pesticide Tolerances. FINAL
RULE.
EPA's decision to grant several tolerances needs to be
read. EPA states: "The cyhalothrins
induce clinical signs of neurotoxicity in at least three species
(rats, mice and dogs), and a developmental neurotoxicity (DNT)
study has been required. A subchronic neurotoxicity study
has recently been submitted but has not yet been reviewed;
a preliminary review found that the NOAELs are higher than
endpoints selected by EPA and this study is not expected to
change conclusions of this risk assessment.
EPA
has required that a DNT be conducted for lambda-cyhalothrin
based upon structure activity relationship (SAR), mode of
action, and toxicity information that identifies cyhalothrin
and lambda-cyhalothrin as neurotoxic pesticides. Developmental
neurotoxicity testing with cyhalothrin is required, to further
characterize the potential hazard to the developing animal,
in accordance with standard OPP guidance. This determination
was based upon a weight-of-evidence evaluation of the database..."
