Adequate enforcement method for the combined
residues of total fluroxypyr is available to enforce the tolerance
expression in or on food. The analytical method uses capillary
GC and mass selective
detection (MSD) with LOQ of 0.01 ppm. Fluroxypyr has also
been tested through the Food and Drug Administration (FDA),
Multi-residue Methodology, Protocols C, D, and E. The results
have been published in the FDA Pesticide Analytical Manual,
volume 1. |

Pesticide
Tolerances for Emergency Exemptions. FINAL RULE.
EPA, on its own initiative, in accordance with sections 408(e)
and 408(l)(6) of the Federal Food, Drug, and Cosmetic Act
(FFDCA), 21 U.S.C. 346a, is establishing a tolerance for combined
residues of the herbicide fluroxypyr 1-methylheptyl ester
1-methylheptyl ((4-amino-3,5-dichloro-6-fluoro-2-pyridinyl)oxy)acetate
and its metabolite fluroxypyr
[((4-amino-3,5-dichloro-6-fluoro-2-pyridinyl)oxy)acetic acid],
in or on
This
tolerance will expire and is revoked on June 30, 2007.
Although this tolerance will expire and is revoked on June
30, 2007, under section 408(l)(5) of the FFDCA, residues of
the pesticide not in excess of the amounts specified in the
tolerance remaining in or on onion after that date will not
be unlawful, provided the pesticide is applied in a manner
that was lawful under FIFRA, and the residues do not exceed
a level that was authorized by this tolerance at the time
of that application. EPA will take action
to revoke this tolerance earlier if any experience with, scientific
data on, or other relevant information on this pesticide indicate
that the residues are not safe.
Because
this tolerance is being approved under emergency conditions
identified in the state of Colorado,
EPA has not made any decisions about whether fluroxypyr 1-methylheptyl
ester meets EPA's registration requirements for use on onion
or whether a permanent tolerance for this use would be appropriate.

Fluroxypyr
1- methylheptyl ester
and Fluroxypyr. Pesticide petition for several tolerances.
-- Reproductive and developmental toxicity. The first in Wistar
rats showed no effect on fertility or reproductive performance
and had a NOAEL of 500 mg/kg/day (highest dose tested). The
second study in Sprague-Dawley
rats showed a parental NOAEL for systemic effects of 100
mg/kg/day in male rats and 500
mg/kg/ day in female rats. The NOAEL for
reproductive effects was 750 mg/kg/ day for males and 1,000
mg/kg/day for females (highest dose tested). The NOAEL for
neonatal effects was 500 mg/kg/day.
-- Subchronic toxicity. Fluroxypyr MHE showed a NOAEL of 1,000
mg/ kg/day in a 90-day rat dietary study and a 21-day rabbit
dermal study. Ninety day feeding studies with fluroxypyr showed
NOAELs of 80 mg/kg/ day (Wistar rats),
700 mg/kg/day (Fischer 344 rats),
1,342 mg/kg/day (male mice),
and 1,748 mg/kg/day (female mice).
In a 4-week dietary, range finding study with fluroxypyr in
dogs the NOAEL found was > 50 mg/kg/day.
-- Metabolite toxicology.
Administration of fluroxypyr, as the acid or methylheptyl
ester in a variety of toxicological studies, has produced
similar effects. The
principal response to sufficiently high dosages, whether
administered over the short-term or, in some cases, over a
lifetime, was nephrosis.
Fluroxypyr is an organic acid that is actively excreted into
the urine by the kidney. Thus,
the target organ and dose response
relationship for fluroxypyr toxicity is entirely consistent
with the data on the toxicokinetics of fluroxypyr. Metabolism
studies have shown that fluroxypyr MHE is rapidly and completely
hydrolyzed to fluroxypyr acid and methylheptanol.
