The analytical method involves separate analyses
for parenand its metabolites. The parent is analyzed by GC/electron
capture detection (ECD). The metabolites are derivatized with
boron trifluoride and acetic anhydride for analysis by GC/mass
spectrometry detection (MSD) using selective ion monitoring.

Extension
of Tolerances for Emergency Exemptions. FINAL RULE.
EPA
has authorized under FIFRA section 18 the use of carfentrazone-ethyl
on fruiting vegetables group 8
for control of paraquat resistant nightshade, common groundsel
and morningglory in Florida. This
regulation extends a time-limited tolerance for
combined residues of the herbicide carfentrazone-ethyl

•
Residues were not found in the exaggerated rate samples,
and therefore, processing was not conducted for most of the
crops.
• Low level residues were
found in the control samples in 7 of the 12 trials ranging
from an estimated 0.02 ppm to 0.07 ppm.
•
Genotoxicity.
There was a positive response in the
chromosome aberration assay without activation
•
Reproductive and developmental toxicity.
In the developmental toxicity studies,
the
rat and rabbit maternal NOELs were 100 mg/kg/day and 150 mg/kg/day,
respectively. The developmental NOEL for the rabbit was greater
than 300 mg/kg/day, which was the HDT and for the rat the
NOEL was 600 mg/kg/day based on increased litter incidences
of thickened and wavy ribs at 1,250 mg/kg/day. These two findings
(thickened and wavy ribs) are not considered adverse effects
of treatment but related delays in rib development which are
generally believed to be reversible.
•
Chronic toxicity.
A 2-year Combined Chronic Toxicity/Oncogenicity study in the
rat was negative for carcinogenicity and had a chronic toxicity
NOEL of 200 ppm (9 mg/kg/day) for males
and 50 ppm (3 mg/kg/day) for females
based on red fluorescent granules consistent with porphyrin
deposits in the liver at the
500 and 200 ppm levels, respectively. |

Carfentrazone-ethyl.
Extension of tolerances
for Emergency Exemptions. FINAL RULE. EPA
has authorized under FIFRA section 18 the use of carfentrazone-ethyl
on hops for control of hops sucker growth to indirectly control
powdery mildew in Idaho, Oregon, and Washington.
This regulation extends a time-limited tolerance for combined
residues of the herbicide and its metabolite carfentrazone-chloropropionic
acid ([alpha],2-dichloro-5-[4- (difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]-4-
fluorobenzenepropanoic acid) in or on
hop, dried cone at 0.30 ppm for an additional 2-year period.
This tolerance will expire and is revoked on June 30, 2005.
A time-limited tolerance was originally published in the Federal
Registerof August 1, 2001 (66 FR 39640) (FRL-6792 -2) |

Pesticide
Tolerances for Emergency Exemptions. FINAL
RULE. This regulation establishes a 2-year time-limited
tolerance for the combined residues
of carfentrazone-ethyl and and carfentrazone-ethyl
chloropropionic acid in
or on fruiting vegetables (except cucurbits) (crop group 8)
(0.10 ppm), tomato paste (0.60 ppm) and tomato puree (0.60
ppm).
These tolerances will expire and are revoked on June 30, 2004.
Because these tolerances are being approved under emergency
conditions, EPA has not made any decisions about whether carfentrazone-
ethyl meets EPA's registration requirements for use on fruiting
vegetables (except cucurbits) (crop group 8) or whether a
permanent tolerance for this use would be appropriate.
-- Two-year chronic toxicity study in rats. LOAEL = 12 mg/kg/day
based on liver histopathology
(increases in microscopic red fluorescence
of the liver, liver pigment) and total
mean urinary porphyrin.
-- Subchronic oral toxicity study in the dog. LOAEL = 150
mg/kg/day based on decreased body weight gain and increased
porphyrin levels.
-- Chronic toxicity study in rats. LOAEL = 12 mg/kg/day based
on liver histopathology
and increased urinary porphyrin
levels.
-- Examination of fetuses for alterations
of external, visceral, and skeletal development revealed significantly
increased litter incidences of wavy and thickened ribs in
the 1,250 mg/kg/day treatment group. The
developmental LOAEL is 1,250 mg/kg/day (based upon a significant
increase in the litter incidences of wavy and thickened ribs);
the developmental NOAEL is 600 mg/kg/day.
-- In a developmental toxicity study
in rabbits, evidence of treatment-related maternal toxicity
consisted of unthriftiness and emaciation in
two does at 300 mg/kg/day. |
