- Schedule for Reregistration & Tolerance Reassessment (RED)
is expected to be July 2005. Contact at EPA: Lance Wormell (703)
603-0523; email@example.com . According to EPA:
Through the pesticide reregistration and tolerance reassessment
programs, EPA is assessing risks and making risk management
decisions for older pesticides. These decisions are summarized
in documents known as REDs, IREDs, and TREDs. By making decisions
according to the schedule below, EPA will meet its statutory
deadlines for completing reregistration and tolerance reassessment.
Some of the decision dates presented in the schedule may change
due to the dynamic nature of the review process. Any pesticide
decisions that are not completed during the current fiscal year
will be rescheduled for the following year. EPA is committed
to meeting its reregistration and tolerance reassessment deadlines.

Fluazifop- P - butyl: Material
Data Safety Sheet for Fusilade DX. Syngenta.
One of 8 fluorinated pesticides used to cultivate grapes in
Kern County, California. The community
asked ATSDR, EPA, state, and local agencies to provide assistance
in evaluating current health conditions in the area. Health
concerns include a perceived increase in the number of childhood
cancer cases, incidence of adult cancers, low birth weight,
miscarriages, and developmental anomalies. The community is
surrounded by agricultural fields where ground and aerial
application of pesticides and fertilizers are reported to
occur frequently. According to residents, during periods of
heavy rain, surface water run-off appears to flow through
the neighborhood into sump areas. Potential contaminated soil
from surface water run-off is also of concern. The drinking
water issue is of primary concern, specifically the status
of municipal wells used for drinking water in the neighborhood...
Fusilade (fluazifop-p-butyl) was one
of 6 substances found in an analysis of the community's drinking
water at low concentrations in three samples at levels of:
0.16 µg/L, 0.06 µg/L, and 0.17 µg/L. Fusilade is not
a common contaminant of groundwater because it is rapidly
broken down in water and has low mobility in soils. It is
listed as an EPA class IV contaminant
and is considered relatively nontoxic.

Data for Fluazifop-butyl
Data for Fluazifop
submitted metabolism data on fluazifop-butyl
and fluazifop-P-butyl (the subject of reregistration)
support the finding that they are
similar, if not identical in toxicity. Rat metabolism
data showed that [RS] fluazifop-butyl is converted to [R]
fluazifop acid within a short time period. Fluazifop-butyl
is rapidly hydrolyzed to fluazifop acid by blood esterases
and the [S] enantiomer is rapidly converted to the [R] enantiomer;
apparently the [R] enantiomer is the preferred configuration.
Whether rats are administered [RS] fluazifop-butyl (50:50
mixture) or [R] fluazifop-P-butyl (purified, 90%:10%= [R]:[S]),
a ratio of [R]:[S]= 97%:3% for fluazifop acid was identified
within a hour in the blood of rats (Page 9) ... Based on
their structures, the Metabolism Assessment Review Committee
(MARC) was unable to conclude that the major
metabolites of fluazifop-P-butyl will be significantly
less toxic than the parent and therefore, recommended that
for risk assessment purposes, the
residues of concern are parent, fluazifop acid (free and
conjugated), 5-trifluoromethyl-2-pyridone, and 2-(4hydroxyphenoxy)
propionic acid (free and conjugated).
