Additionally,
an
import

been
established.
Triadimenol

are
marketed
in
the
U.
S.
under
the

.
The
reregistration
of
triadimenol
is
being
supported
by
Bayer
CropScience
(
Bayer),
the
basic
producer.
The
triadimenol
formulations
registered
for
food/

uses
include
wettable

in/
on
various
plant
commodities
[
40
CFR
§
180.450(
a)].
The
established
tolerances
for
plant
commodities
range
from
0.01
ppm
(
sorghum
grain
and
fodder)
to
2.5
ppm
(
green
forage
of
oats,
rye,
and
wheat).
Tolerances
are
established
for
residues
of
triadimenol
and
its
metabolites
containing
the
chlorophenoxy
moiety
(
calculated
as
triadimenol)
in/
on
livestock
commodities
at
0.01
ppm
(
milk,

poultry
commodities)
and
0.1
ppm
(
fat,
meat,
and
meat

of
cattle,
goats,
hogs,
horses,
and
sheep).

Triadimenol
and
its
butanediol
metabolite
(
KWG
1342)
are
also
regulated
as
metabolites
of
the
fungicide
triadimefon
(
40
CFR
§
180.410).
In
addition,
40
CFR
§
180.3(

specifies
that

are
established
for
residues
of

commodity
and
its
products
thereof,
the
total
amount
of
such
residues
shall
not
yield
more
residue
than
that
permitted
by
the
higher
of
the
two
tolerances.
Currently,
triadimefon
and
triadimenol
do
not
share
any
uses,
so
40
CFR
§
180.3(
d)(
13)
should
be
deleted.

The
reregistration
requirements
for
plant
metabolism
have
not
been
fulfilled.
No
metabolism
studies
with
triadimenol
have
been
submitted;
however,
metabolism
studies
with
triadimefon
have
been
received
and
reviewed.
The
Health
Effects
Division
(
HED)
has
examined
the
results
of
these
studies
and
determined
that
the
triadimefon
residues
of
concern
in/
on
apples,
grapes,
pears,
pineapples,
and
raspberries
for
tolerance
expression
are
triadimefon
and
triadimenol
and
for
risk
assessment
are
triadimefon,
triadimenol,

and
KWG

(
S.
Ary,

2005).
Of
these
compounds,
triadimenol
and
KWG
1342
are
currently
regulated
for
plant
commodities.

HED
has
determined
that
translation
of
metabolism
data
from
triadimefon
to
triadimenol
is
not
appropriate
for
the
existing
uses
on
cereal
grains
and
cotton.
The
metabolism
studies
with
triadimefon
were
conducted
using
a
foliar
application
and
triadimenol
is
used
only
as
a
seed
treatment.
Additionally,
in
the
submitted
triadimenol
seed
treatment
wheat
study,
residues
in
grain
were
not
identifiable
due
to
the
low
activity
found
in
wheat
grain.
Therefore,
HED
concludes
that
the
nature
of
the
residue
in
cereal
grains
and
cotton
is
not
adequately
understood;
however,
based
on
chemical
structure
and
the
probable
metabolic
pathway
of
triadimenol,
the
residues
of
concern
for
tolerance
expression
and
risk
assessment
are
likely
to
be
triadimenol,

Separate
metabolism
studies
with
triazole­
14C
and
phenyl­
14C
labeled
triadimenol
applied
as
a
seed
treatment
to
corn
or
wheat
and
cotton
should
be
conducted
to
confirm
the
residues
of
concern.
The
residues
of
concern
for
tolerance
expression
and
risk
assessment
for
bananas
are
triadimenol
and
KWG
1342.

Additionally,
the
Agency
does
have
concern
about
the
potential
toxicity
of
1,2,4­
triazole
and
two
conjugates,
triazole
alanine
and
triazole
acetic
acid,
which
are
metabolites
common
to
most
of
the
triazole
fungicides.
To
support
the
extension
of
existing
and
granting
of
new
parent
triazolederivative
fungicide
tolerances,
the
Agency
will
be
conducting
a
human­
health
assessment
for
aggregate
exposure
to
1,2,4­
triazole.

The
reregistration
requirements
for
livestock
metabolism
are
fulfilled
based
on
acceptable
goat
and
poultry
metabolism
studies
submitted
to
support
reregistration
of
triadimefon.
HED
has
determined
that
the
residues
of
concern
for
tolerance
expression
and
risk
assessment
in
livestock
are
triadimenol
and
KWG
1342.

The
Pesticide
Analytical
Manual
(
PAM)
Vol.
II
does
not
contain
a
listing
for
triadimenol
(
February
1997
Index).
However,
the
methods
listed
for
triadimefon
can
be
used
for
the
determination
of
triadimenol,
KWG
1323,
KWG
1342,
and
KWG
1732.
PAM
lists
two
gas
chromatography
with
mass
spectrometry
detection
(
GC/
MS)
methods
(
Methods
I
and
II)
for
the
determination
of
triadimenol
and
its
free
and
conjugated
metabolites
in
plant
and
livestock
commodities.
Both
methods
are
common
moiety
methods.
The
reported
limit
of
quantitation
(
LOQ)
is
0.05
and
limit
of
detection
(
LOD)
is
0.01
ppm
for
both
methods.

In
conjunction
with
triadimefon
reregistration,
Bayer
has
proposed
a
GC/
MS
method
(
Report
No.
106549)
for
enforcement
of
tolerances
for
residues
of
triadimefon,
triadimenol,
KWG
1342,
KWG
1323,
and
KWG
1732
in/
on
barley,
corn,
cotton,
oat,
rye,
and
wheat
commodities.
The
method
has
been
successfully
radiovalidated
and
has
undergone
independent
laboratory
validation.
The
reported
method
LOQ
is
0.05
ppm
for
each
analyte
in
cereal
grains
and
0.02
ppm
in
each
analyte
in
cotton.
Additionally,
a
GC
method
using
a
nitrogen
phosphorus
detector
(
NPD;
Report
No.
80488)
is
available
for
determination
of
residues
of
triadimenol,
KWG
1342,
and
KWG
1323
and
is
adequate
for
the
enforcement
of
the
banana
tolerance.
The
method
has
undergone
a
successful
Agency
method
validation
on
tomatoes
and
was
submitted
to
the
FDA
for
publication
in
PAM
Vol.
II.
The
reported
method
LOQ
is
0.01
ppm
for
each
analyte.

The
reregistration
requirements
for
multiresidue
method
testing
for
residues
of
triadimenol,
KWG
1342,
and
KWG
1732
are
satisfied.

The
reregistration
requirements
for
storage
stability
data
are
not
satisfied
for
field
corn,
sweet
corn,
cotton,
and
wheat
forage,
hay,
straw,
and
processed
commodities
pending
the
results
from
the
requested
metabolism
studies.

The
reregistration
requirements
for
data
depicting
the
magnitude
of
triadimenol
residues
of
concern
in
meat,
milk,
poultry,
and
eggs
have
been
fulfilled.
Acceptable

have
been
submitted
and
evaluated.
Triadimenol
is

current
uses.
HED
concludes
that
the
supported
uses
on
barley,
corn,
cotton,
oats,
rye,
and
wheat
result
in
a
40
CFR
§
180.6(

3)
situation
for
ruminant
commodities;
i.
e.,
there
is
no
reasonable
expectation
of
finite
residues
in
ruminant
commodities.
Therefore,
additional
data
on
the
transfer
of
residues
to
meat,
milk,
poultry,
and
eggs
are
not
required
and
all
tolerances
for
livestock
commodities
should
be
revoked
pending
results
from
the
requested
corn
and
wheat
metabolism
studies.
If
registration
on
additional
commodities
and
livestock
feed
items
are
requested,
then
triazole
and
phenyl­
labeled
livestock
metabolism
studies
would
be
required.
Such
data
may,
in
turn,
trigger
the
need
for
magnitude
of
the
residue
(
feeding)
studies
in
livestock.

The
reregistration
requirements
for
magnitude
of
the
residue
in/
on
bananas
are
fulfilled.
Additional
field
trials
conducted
with
field
corn
(

cotton
(

and
wheat
(
forage,

are
required
pending
the
results
from
the
requested

studies.

The
reregistration
requirements
for
magnitude
of
the
residue
in
the
processed
commodities
of
field
corn
and
cotton
have
been
fulfilled.
A
wheat

study
conducted
with
triadimenol
applied
to
wheat
as
a
seed
treatment
should
be
submitted
once
the
requested
wheat

have
been
submitted
and
reviewed.

No
data
pertaining
to
confined/
field
accumulation
of
triadimenol
residues
in
rotational
crops
have
been
submitted;
however,
confined
rotational
crop
data
for
triadimefon
have
been
submitted
and
translated.
The

Table
A
comprehensive
summary
of
triadimenol
food/
feed
use
patterns
based
on
the
product
labels
registered
to
Bayer,
was
prepared
by
the
Biological
and
Economic
Analysis
Division
(
BEAD;
dated
3/
2/
2005)
and
is
presented
in
Appendix
1.
A
tabular
summary
of
the
residue
chemistry
science
assessments
for
reregistration
of
triadimenol
is
presented
in
Table
5.
The
conclusions
listed
in
Table
5
regarding
the
tolerance
reassessment
eligibility
decision
of
triadimenol
food/
feed
uses
are
based
on
the
use
patterns
being
supported
by
the
basic
producer,
Bayer.
When
end­
use
product
data
call
in's
(
DCIs)
are
developed
(
e.
g.,
at
issuance
of
the
TRED),
the
Registration
Division
(
RD)
should
require
that
all
end­
use
product
labels
(
e.
g.,
MAI
labels,
special
local
needs
(
SLNs),
and
products
subject
to
the
generic
data
exemption)
be
amended
such
that
they
are
consistent
with
the
labels
registered
to
the
basic
producer.

As
indicated
in
the
triadimenol
use
closure
memorandum
(
J.
Pates,
7/
26/
2004),
Bayer
is
no
longer
supporting
the
use
of
triadimenol
on
sorghum
and
has
intentions
on
deleting
the
use
from
all
labels.

Nature
of

Plants
The
reregistration
requirements
for

metabolism
have
not
been
fulfilled.
Two
metabolism
studies
with
triadimenol
have
been
submitted
and
are
currently
under
review
by
the
Agency
and
are
summarized
below.

In
the
wheat
study
(

wheat
seeds
were
treated

at
the
currently
registered
rate
of
0.5
oz

wheat
straw,
triadimenol
accounted
for

It
is
noted
that

accounted
for
17.7%
of
the

and
a

triadimenol
was
found
at
73.1%
TRR,
two
glucosides
of
triadimenol
were
found
at
a
total
of
15.9%
TRR,
and
KWG

In
the
cucumber

studies,
seedlings
were
treated
with
[
phenyl­

triadimefon
at
approximately
1x

released
triadimefon
and
triadimenol,
as
well
as
low

and
KWG

These
additional

Degradation
of
triadimefon
in
mature
cucumber
and
tomato
plants
appeared
to
be
similar
to
that
in
the
seedlings,
with
minor
differences.
The
fruit
and
foliage
differed
in
their
ability
to
metabolize
the
parent.
In
both
tomato
and
cucumber
fruit,
the
terminal
degradation

was
primarily
triadimenol,
while
the
foliage
of
both
tomato
and
cucumber
exhibited
a
more
complex
series
of

in
either
tomatoes
or

Grape
(
MRID

In
a
grape
metabolism
study,
mature
fruit
were
harvested
56
days
following
treatment
of
an
established
vine
with
[
phenyl­

triadimefon;
immature
fruit
were
harvested
at
various
earlier
intervals.
A
rapid
decline
in
total
radioactivity
was
observed,
due
to
the
volatility
of
triadimefon.
The
decline
in
the
quantity
of
parent
observed
was
accompanied
by
a
buildup
of
the
metabolite
triadimenol.
Triadimenol
accounted
for
55.6%
of
TRR
in
mature
grapes
while
triadimefon
was
only
detected
at
1.1%
TRR.
The
remainder
of
the
identified

was
comprised
of
KWG
1342
and
its

(
15.5%
TRR),
triadimenol

triadimefon
at
a
rate
of
236
g
ai/
A,
approximately
2x
the

was
the
major

a
glucoside
of
KWG
1342
was
the
other
major
residue
identified
(
21%

Additionally,
triadimefon
accounted
for

was
found
at
6%

pchlorophenol
was
also
identified
at
5%

triadimefon
was
found
at
31­
74%
TRR
and
triadimenol
was
found
at
12­

together
they
accounted
for
the
majority
of
residues
(
66­
86%

p­
chlorophenol
and
its
glucoside
were
also
identified,
at
9­
16%
TRR.
In
wheat
straw,
triadimenol
and
its
conjugates
accounted
for
the
majority
of
the
radioactivity
at
53%
TRR
and
triadimefon
accounted
for
only
1%
TRR;
p­
chlorophenol
and
its
conjugates
and
KWG
1342
and
its
conjugates
were
also
identified,
at
21%
and
19%
TRR,
respectively.

The
Health
Effects
Division
(
HED)
has
examined
the
results
of
these
studies
and
determined
that
the
triadimefon
residues
of
concern
in/
on
apples,
grapes,
pears,
pineapples,
and
raspberries
for
tolerance
expression
are
triadimefon
and
triadimenol
and
for
risk
assessment
are
triadimefon,
triadimenol,
KWG
1323,
and
KWG
1342
(
S.
Ary,
D314742,
11/
23/
2005).
Of
these
compounds,
triadimenol
and
KWG
1342
are
the
compounds
that
are
currently
regulated
for
plant
commodities.
The
chemical
names
and
structures
of
these
compounds
are
presented
in
Table
3.

HED
has
determined
that
translation
of
metabolism
data
from
triadimefon
to
triadimenol
is
not
appropriate
for
the
existing
uses
on
cereal
grains.

and
triadimenol
is
used
only
as
a

In
the
submitted
triadimenol
wheat
study,
residues
in
grain
were
not
identifiable
due
to
the
low
activity
found
in
wheat
grain.
Therefore,
HED
concludes
that
the
nature
of
the
residue
in
cereal
grains
is
not
adequately
understood;
however,
based
on
chemical
structure
and
the
probable
metabolic
pathway
of
triadimenol,
the
residues
of
concern
for
tolerance
expression
and
risk
assessment
are
likely
to
be
triadimenol,
KWG
1342,
and
KWG
1732
in/
on
cereal
grains
(
barley,
corn,
oats,
rye,
and
wheat)
and
cotton.
The
wheat
metabolism
study
conducted
with
triadimefon
indicate
that
KWG
1732
is
the
major
metabolite
found
in
grain
at
35%
TRR
and
KWG
1342
at
21%
TRR
in
grain.
Triadimenol
accounted
for
12%
TRR.
It
is
also
noted
that
the
submitted
wheat
processing
study
conducted
with
triadimenol
applied
as
a
seed
treatment
identified
quantifiable
residues
of
KWG
1732.
There
have
been
no
previous
triazole
labeled
studies
conducted
with
triadimenol
applied
as
a
seed
treatment
to
commodities
and
data
from
the
available
soil
metabolism
studies
conducted
with
triadimefon
indicate
that
soil
microbes
metabolize
the
triazole
fungicide
to
free
triazole,
which
may
be
taken
up
into
the
plant.
Separate
metabolism
studies
with
triazole­
14C
and
phenyl­
14C
labeled
triadimenol
applied
as
a
seed
treatment
to
corn
or
wheat
and
cotton
should
be
conducted
to
confirm
the
residues
of
concern.

The
residues
of
concern
for
tolerance
expression
and
risk
assessment
for
bananas
are
triadimenol
and
KWG
1342,
which
are
based
on
the
available
metabolism
data
conducted
with
triadimefon
applied
to
an
established
grape
vine
and
the
field

data
conducted
with
triadimenol
applied
to
the
soil
of
banana
groves.
The
metabolism
study
conducted
with
triadimefon
applied
to
grapes
indicate
that
triadimenol
is
the
major
metabolite
identified
at
56%
along
with
KWG
1342
at
16%.
The
available
field
trial
data
indicate
that
residues
of
triadimenol
and
KWG
1342
are
both
likely
to
be
found
in/

as
indicated
in

poultry
metabolism
studies
submitted
to
support
reregistration
of
triadimefon.

For
the
ruminant
study,
a
lactating
goat
received
[
phenyl­
14C]
triadimefon
at
86.4
ppm
for
three
consecutive

in
milk
and
fat
(<
5%
TRR)
but
was
not
detected
in
kidney,
liver,
or

The
major
residue
identified
was
KWG
1342
glucuronide
(
6­
47%
TRR).
Triadimenol
and
its
conjugates
comprised
a
major
portion
of
the
residue
in
tissues
and
milk
(
totals
of
9­
42%
TRR).
The
remainder
of
the
radioactivity
was
identified
as
KWG

and
its

16
laying
hens
received
[

triadimefon
at
28.7

Triadimefon
was
identified
in

Triadimenol
and
its

were
the
major

for
the
determination
of
triadimenol
and
its
free

conjugated
metabolites
in
all
crops.
Both
methods
are
common

methods.
In
Method
I,
residues
are
extracted
using
methanol
or
methanol:
acetone
(
2:

Following
cleanup
on
an

p­
Chlorophenol
is

and
then
derivatized
with
dinitrofluorobenzene
for

and
the
other
containing
KWG

the
maximum

situation
for

commodities;
i.
e.,
there
is
no

commodities.
Therefore,
additional
data
on
the
transfer
of
residues
to
meat,
milk,
poultry,
and
eggs
are
not
required
and
all
tolerances
for

pending
results
from
the
requested
corn

studies.
If
registration
on
additional
commodities
and
livestock
feed
items
are
requested,
then
triazole
and
phenyl­
labeled
livestock

studies
would
be
required.
Such

The

instead,
cited
a
wheat

submitted
to
fulfill
reregistration

for

(
MRID

In
that

A/

At
the

aspirated
grain
fractions
were
collected
(

and
wheat
grain
samples
were
processed
into

wheat

flour,
middlings,
and
shorts,
using
a
small­
scale
processing
procedure
which
simulated
normal
commercial

These
data
indicate
that
the

residues
of
triadimenol,
KWG

concentrate
by
2.1x
in

However,
the

Instead,
the

proposed
translating
data
from
a
triadimefon
wheat
grain
processing
study;
however,
these
data
cannot
be
translated
to

due
to
differences
in
the
use
patterns
(
seed
treatment
vs.
late

that
are
likely
to
impact
the
potential
concentration
of

A

The
uptake
of
residues
was
lowest
in
radish
bulbs
(
0.30
ppm)
and
highest
in
wheat
straw/
chaff
(
38.46
ppm).
The
pattern
of
accumulation
in
relation
to
rotation
intervals
could
not
readily
be
established
in
radish
commodities;
accumulation
was
highest
at
the
29­
day
rotation
and
declined
in
subsequent
intervals,
but
in
lettuce
and
wheat
commodities,
accumulation
was
lowest
at
the
29­
day
rotation
and
increased
thereafter.
Triadimefon
was
identified
and
quantified
as
a
minor
residue
(#
4%
of
TRR)
in/
on
the
organosoluble
fractions
of
all
commodities,
except
in
wheat
grain
where
the
parent
was
below
the
limit
of
detection
(
0.0072
ppm).
The
principal
metabolites
identified
in
leafy
commodities
and
radish
bulbs
were
triadimenol
and
its
acetylated
or
glucoside
derivatives;
collectively,
these
metabolites
accounted
for
93%
of
TRR
in
29­
DAT
lettuce,
67%
of
TRR
in
161­
DAT
wheat
straw
and
270­
DAT
immature
wheat
or
wheat
forage,
and
87%
of
TRR
in
radish
bulbs.
In
wheat
grain,
the
predominant
compound
identified
was
KWG
1732
which
comprised
63­
91%
of
TRR.

Based
on
this
study,
the
Agency
required
limited
field
rotational
crop
studies
for
triadimefon.
Subsequently,
Bayer
requested
deletion
of
all
rotatable
crop
uses
from
its
triadimefon
product
labels.

The
available
confined
rotational
crop
data
for
triadimefon
indicate
a
potential
for
accumulation
of
triadimenol
residues
of
concern
in/
on
rotatable
crops.
However,
the
application
rate
used
in
the
study
is
much
greater
than
the
expected
"
application"
rate
resulting
from
application
of
triadimenol
to
seed.
In
recently
submitted
triadimenol
processing
studies
(
MRID
44519801­
44519803),
treated
seed
was
planted
at
the
rate
of
13
lb
of
seed/
acre
(
field
corn),
16
lb/
acre
(
cotton),
and
91
lb/
acre
(
wheat).
Based
on
maximum
application
rates
of
0.062
lb
ai
per
100
lb
of
seed
for
corn
and
cotton
and
0.031
lb
per
100
lb
of
seed
for
wheat,
the
equivalent
"
soil
application"
rates
would
be
approximately
0.01
lb
ai/
A
for
corn
and
cotton,
and
0.03
lb
ai/
A
for
wheat.
Therefore,
the
application
rate
of
the
triadimefon
rotational
crop
study
is
approximately
190x
the
maximum
triadimenol
rate
for
annual
crops.
If
the
highest
residue
found
in
rotational
crops,
19.0
ppm
triadimenol
in
wheat
straw,
is
"
corrected"
down
to
a
1x
application,
expected
residues
would
be
0.1
ppm,
which
is
greater
than
0.01
ppm.
Therefore,
the
Agency
concludes
that
limited
field
rotational
crop
studies
for
triadimenol
must
be
submitted
pending
the
results
from
the
requested
metabolism
studies.

and
processed
commodities
and
feedstuffs
derived
from
crops
(
Table

As
a
result
of
changes
to
Table

tolerances
are
now
required
for
RACs
which
have
been
added
to
Table

Also,
some
commodity
definitions
must
be
corrected.
A
summary
of
triadimenol
tolerance
reassessments
is
presented
in
Table

The

Because
of
changes

tolerances
for
barley
hay,
cotton

must
be
proposed.
There
are
no
data
available
for

The
required

Acceptable
feeding
studies
for
ruminants
and
poultry
are
available
to
reassess
the
tolerances
for
the
livestock
commodities.

Triadimenol
is
not
registered
for
use
as
a
direct
livestock
treatment.
The
nature
of
the
residue
in
livestock
is
adequately
defined
for
the
current
uses.
HED
concludes
that
the
supported
uses
on
barley,
corn,
cotton,
oats,
rye,
and
wheat
result
in
a
40
CFR
§
180.6(

situation
for
ruminant
commodities;
i.
e.,
there
is
no
reasonable
expectation
of
finite
residues
in
ruminant
commodities.
Therefore,
additional
data
on
the
transfer
of
residues
to
meat,
milk,
poultry,
and
eggs
are
not
required
and
all
tolerances
for

Codex
Harmonization
The
Codex
Alimentarius
Commission
(
Codex)
has
established
several
maximum
residue
limits
(
MRLs)
for
triadimenol
in/
on
various
raw
agricultural
commodities.
The
Codex
MRLs
are
expressed
in
terms
of
triadimenol

The
MRLs
have
been
established
to
accommodate
triadimenol
residues
resulting
from
the
use
of
triadimefon
and/
or
triadimenol.
Compatibility
cannot
be
achieved
with
the
Codex
MRLs
because
these
levels
are
expressed
in
terms
of
triadimenol
only;
the
U.

are
expressed
in
