Summary
Trifluralin
(
 ,
 ,
 ­
trifluoro­
2,6­
dinitro­
N,
N­
dipropyl­
p­
toluidine)
is
a
dinitroaniline
herbicide
registered
for
weed
control
on
a
wide
variety
of
field,
orchard,
and
vegetable
crops,
although
it
is
used
primarily
on
soybeans
and
cotton.
Reregistration
data
for
trifluralin
are
supported
by
the
Trifluralin
Data
Development
Consortium
(
TDDC).
Trifluralin
end­
use
products
for
food
and
feed
crops
include
emulsifiable
concentrates
(
EC,
36.4,
50.8%
ai)
and
a
granular
formulation
(
G,
10%
ai).
These
formulations
may
be
applied
using
ground
or
aerial
equipment,
with
the
EC
formulations
being
typically
applied
as
aqueous
dilutions.
The
time
of
application
of
trifluralin
may
be
dormant,
preplant,
or
pre­
emergence;
and
application
is
typically
followed
by
incorporation
into
the
soil
by
mechanical
means
or
with
water.

Trifluralin
was
the
subject
of
a
Reregistration
Standard
Science
Chapter
dated
7/
12/
85
and
a
10/
29/
91
Reregistration
Standard
Update.
The
Residue
Chemistry
Chapter
for
the
trifluralin
Reregistration
Eligibility
Decision
(
RED)
was
issued
10/
20/
94
and
the
complete
RED
was
completed
in
April,
1996.

Current
tolerances
(
ranging
from
0.05
ppm
to
2.0
ppm)
are
established
for
residues
of
trifluralin
in/
on
numerous
raw
agricultural
plant
commodities
[
40
CFR
§
180.207].
Adequate
GC/
ECD
methods
are
available
for
enforcing
tolerances
and
collecting
data
on
trifluralin
residues
in/
on
plant
commodities.
Tolerances
for
residues
of
trifluralin
in
livestock
commodities
have
not
been
established.

The
qualitative
nature
of
the
residue
in
plants
is
adequately
understood
based
on
field
corn
and
mustard
green
metabolism
studies,
with
supplemental
metabolism
data
from
carrot,
cotton,
peanut,
soybean,
and
sweet
potato
studies.
The
residue
of
concern
in
plants
is
trifluralin
per
se.

The
Agency
previously
determined
that,
based
on
estimates
of
very
low
dietary
exposure
to
livestock,
there
was
no
expectation
of
finite
residues
occurring
in
livestock
commodities
(
meats,
eggs,
and
milk)
and
tolerances
for
livestock
commodities
were
not
required.
However,
based
on
the
reassessed
tolerances
for
alfalfa
forage
(
3
ppm)
and
hay
(
2
ppm),
the
estimate
of
possible
dietary
exposure
of
trifluralin
to
ruminants
has
increased
significantly.
Therefore,
in
order
to
assess
residue
levels
for
tolerances,
new
metabolism
and
feeding
studies
in
ruminants
are
now
being
required.
The
Agency
continues
to
expect
that
finite
residues
of
trifluralin
will
not
occur
in
hog
and
poultry
commodities
since
alfalfa
is
not
a
feed
item
for
these
non­
ruminants.

With
a
few
exceptions,
adequate
residue
data
are
available
from
crop
field
trials
and
processing
studies
to
support
the
registered
food/
feed
uses
of
trifluralin.
Although
a
substantial
portion
of
the
database
for
the
magnitude,
or
level,
of
trifluralin
residues
in
crops
is
considered
questionable
due
to
storage
stability
concerns,
the
Agency
has
determined
that
sufficient
residue
data
are
available
for
the
reassessment
of
trifluralin
tolerances
for
most
crops
based
on
one
(
or
more)
of
the
following
reasons:
(
1)
the
early­
season
use
pattern
of
trifluralin
in
most
crops
results
in
residues
below
the
4
enforcement
method
quntitation
level
(
0.05
ppm);
(
2)
bridging
studies
from
more
recent
(
adequate)
field
trials
have
residue
levels
that
are
similar
to
residue
levels
in
the
earlier
field
trials;
(
3)
adequate
residue
data
for
some
crops
can
be
translated
to
a
similar
use
on
related
crops;
and
(
4)
numerous
processing
studies,
conducted
at
exaggerated
rates,
indicate
that
trifluralin
residues
in
raw
agricultural
commodities
(
RACs)
are
likely
to
be
nondetectable
(<
0.01
ppm)
following
treatment
at
1x
the
maximum
labeled
rate.

Currently,
rotational
crop
tolerances
and
plant­
back
intervals
are
not
required
for
trifluralin.
However,
the
HED
Metabolism
Assessment
Review
Committee
concluded
(
meeting
date
2/
4/
04)
that,
based
on
a
reassessment
of
the
trifluralin
confined
rotational
study,
a
plant­
back
interval
of
100
days
will
now
be
required
unless
a
new
confined
rotational
study
is
conducted
at
a
1x
rate
with
a
more
comprehensive
characterization/
identification
of
metabolites.

Residue
Chemistry
Deficiencies
"
A
ruminant
metabolism
study
and
a
ruminant
feeding
study
are
required
to
determine
the
appropriate
tolerance
expression
and
tolerance
levels
for
ruminant
commodities.
An
analytical
method
for
determining
trifluralin
residues
in
ruminant
fat,
meat,
meat
byproducts,
and
milk
is
also
required
in
conjunction
with
the
required
cattle
feeding
study.

"
Due
to
concerns
pertaining
to
storage
stability
of
residues,
new
field
trial
data
are
required
depicting
trifluralin
residues
in/
on
wheat
forage,
hay,
and
straw
following
an
application
of
the
EC
and
G
formulations
at
the
maximum
labeled
rate.

"
New
grape,
mint,
and
plum
processing
studies
are
required
due
to
concerns
pertaining
to
storage
stability
of
residues.

"
Residue
data
on
rapeseed
forage
are
required.

a
comprehensive
summary
of
the

The
conclusions
listed
in

regarding
the
reregistration
eligibility
of

are
based
on
the

A
review
of
the
above
EP
labels
and
the
supporting
residue
data
indicate
that
the
following
label
changes
should
be
made:
8
°
Use
directions
for
alfalfa
should
be
clarified
to
list
a
maximum
seasonal
use
rate
of
2
lb
ai/
A
for
the
EC
formulation
and
4
lb
ai/
A
for
the
G
formulation.

°
Use
directions
for
cotton
should
be
clarified
to
specify
a
maximum
seasonal
use
rate
of
2
lb
ai/
A
for
all
use
patterns,
including
use
for
control
of
Johnson
grass.

°
The
feeding/
grazing
restriction
for
rapeseed
forage
should
be
deleted
as
this
type
of
prohibition
is
not
considered
feasible
by
the
Agency.

°
The
feeding/
grazing
restriction
for
barley
should
be
deleted
as
this
type
of
prohibition
is
not
considered
feasible
by
the
Agency.

°
The
feeding/
grazing
restriction
for
flax
straw
should
be
deleted
as
this
type
of

However,
the

Nature
of
the
Residue
­
Plants
The
qualitative
nature
of
trifluralin
residues
in
plants
is
adequately
understood
based
on
field
corn
and
mustard
green
metabolism
studies.
These
studies
are
supplemented
with
carrot,
cotton,
peanut,
soybean,
and
sweet
potato
metabolism
data.
The
residue
of
concern
in
plants
is
trifluralin
per
se
and
the
current
tolerance
expression
for
plants
is
considered
adequate.

Trifluralin
was
the
predominant
residue
in
field
corn
and
mustard
greens.

were
converted
from

Livestock
Trifluralin
metabolism
studies
in
ruminants
and
in
poultry
have
been
submitted
to
the
Agency
and
are
summarized
below.
A
preliminary
dietary
risk
assessment
is
based,
in
part,
on
the
results
of
the
ruminant
metabolism
study,
even
though
the
study
is
considered
to
be
of
low
quality
by
current
standards.
To
address
this
uncertainty
in
the
dietary
risk
assessment
and
to
establish
the
appropriate
tolerance
expression
and
tolerance
levels
in
ruminant
commodities,
the
HED
Metabolism
Assessment
Review
Committee
(
2/

04)
concluded
that
a
new
metabolism
study
in
ruminants
must
be
submitted
as
well
as
a
ruminant
feeding
study
at
1x,
3x,
and
10x
[
based
on
the
reassessed
tolerance
of
3.0
ppm
for
alfalfa
forage
the
(
revised)
maximum
dietary
exposure
for
cattle
is
~
6.0
ppm].
In
addition,
an
analytical
method
for
determining
trifluralin
residues
in
ruminant
fat,
meat,
meat
byproducts,
and
milk
is
required.

Ruminant
Metabolism
In
the
available
ruminant
metabolism
study,
two
steers
were
dosed
with
uniformly
ring­
labeled
[
14C]
trifluralin
at
0.88
ppm
(
0.15x
the
revised
maximum
exposure)
and
8.8
ppm
(
1.5x)
in
the
diet
for
5
and
3
days,
respectively.
In
addition,
two
dairy
cows
were
dosed
with
uniformly
ring­
labeled
[
14C]
trifluralin
at
1.7
ppm
(
0.3x)
and
17
ppm
(
2.8x)
in
the
diet
for
5
and
3
consecutive
days,
respectively.

For
the
steer
dosed
with
[
14C]
trifluralin
at
levels
equivalent
to
0.15x
the
(
revised)
maximum
exposure
for
5
days,
total
radioactive
residues
(
TRR)
were
<
0.001
ppm
in
muscle,
0.004
ppm
in
fat
and
kidney,
and
0.014
ppm
in
liver.
For
the
steer
dosed
with
[
14C]
trifluralin
at
levels
equivalent
to
1.5x
the
(
revised)
maximum
exposure
for
3
days,
TRR
were
0.003
ppm
in
muscle,
0.015
ppm
in
fat,
0.048
ppm
in
kidney,
and
0.145
ppm
in
liver.
Average
TRR
values
in
milk
were
0.0016
ppm
from
the
cow
dosed
at
0.3x
and
0.011
ppm
in
milk
from
the
cow
dosed
at
2.8x.
20
Tissues
from
the
high­
dose
steer
(
8.75
ppm)
and
milk
from
the
high­
dose
cow
(
17
ppm)
were
used
for
characterization
of
the
TRR
in
tissues
and
milk.
Solvent
extraction
and
acid
hydrolysis
extracted
82%
of
the
TRR
from
liver,
and
solvent
extractions
released
69%
of
the
TRR
from
kidney,
88%
of
the
TRR
from
fat,
and
62%
of
the
TRR
in
milk.
Extracted
14C­
residues
were
fractionated
and
characterized
by
column
chromatography,
but
residues
in
milk
and
tissues
were
not
conclusively
identified.
Based
on
thin

data
and
comparison
to

the
following
compounds
were
identified
in

It
should
be
noted
that
the
HED
Metabolism
committee
concluded
(
2/
4/
04)
that
all
trifluralin
metabolites,
including
the
above,
must
be
considered
toxicologically
similar
to
trifluralin
per
se.

Poultry
Metabolism
The
maximum
dietary
exposure
of
trifluralin
to
poultry
is
0.05
ppm
based
on
a
diet
consisting
of
80%
field
corn
grain
and
20%
soybean.
In
the
poultry
metabolism
study,
laying
hens
were
dosed
with
uniformly
ring
labeled
[
14C]
trifluralin
at
0.05
ppm
(
1x)
and
0.5
ppm
(
10x)
in
the
diet
for
five
consecutive
days,
or
at
50
ppm
(
1,000x)
for
ten
consecutive
days.
For
the
1x
dose
group,
TRR
were
nondetectable
in
muscle
(<
0.003
ppm),
skin/
fat
(<
0.003
ppm),
and
eggs
(<
0.001
ppm)
and
0.004
ppm
in
liver.
For
the
10x
dose
group,
TRR
were
nondetectable
(<
0.003
ppm)
in
muscle,
0.002
ppm
in
skin/
fat,
0.014
ppm
in
liver,
and

0.002
ppm
in
eggs.
For
the
1,000x
dose
group,
TRR
were
0.15
ppm
in
muscle,
0.47
ppm
in
skin/
fat,
2.49
ppm
in
liver,
and
0.032­
0.53
ppm
in
eggs.
14C­
Residues
in
eggs
from
the
1,000x
dose
group
plateaued
by
8
days.
TRR
in
eggs
and
tissues
from
the
1,000x
dose
group
were
extracted
and
fractionated,
but
attempts
at
identifying
metabolites
were
unsuccessful.
However,
given
the
low
dietary
exposure
of
trifluralin
residues
to
poultry,
the
Agency
has
concluded
that
further
characterization
and
identification
of
14C­
residues
in
eggs
and
tissues
is
not
required.

an

In
the
Residue
Chemistry
Chapter
of
the
Trifluralin
RED
(
10/

the
data
requirements
for
magnitude
of
trifluralin
residues
in
livestock
were
waived
(
R.
Perfetti,
2/
4/
93)
based
on
the
low
levels
of
radioactive
residues
shown
in
the
animal
metabolism
studies
and
the
low
dietary
trifluralin
exposure
estimated
for
cattle.
The
Agency
concluded
that
tolerances
for
trifluralin
in
fat,
meat,
meat
byproducts,
and
milk
were
not
necessary
as
there
was
no
expectation
for
finite
residues
occurring
in
animal
commodities
[
40
CFR
180.6(
a)(
3)].

However,
residue
data
from
alfalfa
field
trials
indicate
that
the
estimated
maximum
dietary
intake
of
trifluralin
by
cattle
may
be
significant
due
to
residues
in/
on
alfalfa
forage
and
hay,
which
are
major
livestock
feed
items.
In
the
recent
alfalfa
field
trials,
maximum
trifluralin
residues
at
the
labeled
21­
day
PHI
were
2.2
ppm
in/
on
alfalfa
forage
and
1.6
ppm
in/
on
alfalfa
hay,
and
the
highest
average
field
trial
(
HAFT)
residues
were
2.0
ppm
in/
on
alfalfa
forage
and
1.3
ppm
in/
on
alfalfa
hay.

The
maximum
dietary
exposure
for
beef
and
dairy
cattle
is
calculated
below
in
Table

using
the

tolerance
for

Based

at

these

was
limited;
however,

of
the
dosing
period
(
3
days)
the
Agency
requires
new
metabolism
and
feeding
studies
in
ruminants.

Hogs:
The
maximum
dietary
trifluralin
exposure
for
hogs
is
estimated
to
be
0.15
ppm
based
on
a
diet
including
10%
carrot
culls,
25%
soybean
seed
or
meal,
and
65%
corn
grain.
As
the
Agency
continues
to
expect
that
finite
residues
of
trifluralin
will
not
occur
in
hog
commodities,
tolerances
for
hog
commodities
are
not
required.

Eggs
and
fat,
meat,
and
meat
byproducts
of
poultry
Based
on
a
dietary
exposure
of
0.05
ppm
for
poultry,
and
data
from
the
poultry
metabolism
study,
the
Agency
has
concluded
that
residues
of
trifluralin
are
unlikely
to
be
detectable
in
eggs
and
poultry
commodities
[
40
CFR
§
180.6(
a)(
3)].
Therefore
a
poultry
feeding
study
and
tolerances
for
poultry
commodities
are
not
required.

HED
noted
that

of
particular
concern
because

Based
on

HED
considers
field

for
the
following
crops/

to
be
inadequate,
or
questionable:
almonds;
apricots;
barley
(

Although
a
substantial

of
the

for
trifluralin
is
considered
questionable,
the
Agency
has
determined
that
sufficient
residue

are
available
for
reassessment
of
trifluralin
tolerances
for
most
crops
based
on
the
following:
(

and
(

discussed
below.

For
root
and
tuber
vegetables,
adequate
residue
data
are
available
to
support
the
separate
tolerance
for
carrots.
Adequate
residue
data
are
also
available
from
recent
radish
field
trials,
which
will
be
used
as
a
bridging
study.
In
addition,
supporting
residue
data
are
available
from
a
sugar
beet
processing
study
conducted
at
5x,
in
which
residues
in/
on
the
RAC
were
nondetectable
(<
0.01
ppm).
Adequate
field
trial
data
are
also
available
on
sugar
beet
tops
and
turnip
tops
to
support
a
tolerance
on
leaves
of
root
and
tuber
vegetables.
Therefore,
no
additional
root
and
tuber
vegetable
field

25
data
are
required.

Although
the
existing
garlic
and
dry
bulb
onion
residue
data
are
considered
questionable,
the
recent
green
onion
residue
data
are
adequate
and
will
be
used
as
bridging
data.
Therefore,
no
additional
bulb
vegetable
field
trial
data
are
required.

For
leafy
vegetables
(
except
Brassica),
adequate
residue
data
are
available
to
support
the
use
on
celery
and
these
data
will
be
translated
to
support
the
use
on
endive.
There
are
no
other
registered
uses
for
trifluralin
on
crops
in
group
4.

For
Brassica
leafy
vegetables,
adequate
residue
data
are
available
on
the
representative
commodities
broccoli,
cabbage,
and
cauliflower.
Therefore,
no
additional
Brassica
vegetable
field
trial
data
are
required.

Although
the
existing
field
trial
data
on
beans
(
lima
and
dry),
peas
(
field,
dry
and
succulent),
and
soybean
seeds
are
questionable,
the
available
soybean
processing
study
will
be
used
as
bridging
data
to
support
the
legume
vegetables
crop
group.
Residues
in/
on
soybeans
were
nondetectable
(<
0.01
ppm)
following
an
application
at
3.8x
the
maximum
use
rate
on
beans
(
and
peas)
and
1.9x
the
maximum
use
rate
on
soybeans.

For
foliage
of
legume
vegetables,
the
available
bean
and
pea
vine,
hay,
and
straw
residue
data
are
questionable.
However,
the
available
soybean
forage
and
hay
data
are
adequate
and
will
be
used
as
bridging
data
to
support
the
crop
group
tolerance.

For
the
fruiting
vegetables,
adequate
residue
data
are
available
on
tomatoes
and
peppers
to
support
the
crop
group.

For
cucurbit
vegetables,
the
existing
cantaloupe,
cucumber
and
watermelon
residue
data
are
considered
questionable.
However,
the
recent
summer
squash
residue
data
are
adequate
and
will
be
used
as
bridging
data.
Therefore,
no
additional
cucurbit
field
trial
data
are
required.

Although
the
existing
citrus
fruit
field
trial
data
are
questionable,
the
available
citrus
processing
study
(
5x)
is
adequate
and
will
be
used
as
bridging
data.
Following
a
directed
broadcast
application
of
trifluralin
at
5x
to
the
ground
around
orange
trees,
trifluralin
residues
in/
on
oranges
were
nondetectable
(<
0.01
ppm).
No
additional
citrus
fruit
field
trial
data
are
required.

For
stone
fruits,
the
existing
apricot,
peach
and
plum
residue
data
are
considered
questionable.
However,
the
recent
cherry
residue
data
are
adequate
and
will
be
used
as
bridging
data.
Therefore,
no
additional
stone
fruit
field
trial
data
are
required.

For
the
tree
nuts,
all
of
the
available
residue
data
on
almonds,
pecans,
and
walnuts
are
now
considered
to
be
questionable.
However,
based
on
tree
nut
field
trial
data
and
the
weight
of
evidence
for
trifluralin
residues
in
tree
crops,
HED
continues
to
26
expect
that
trifluralin
residues
will
be
nondetectable
(<
0.01
ppm)
in
tree
nuts
and
almond
hulls.
Therefore,
no
additional
tree
nut
field
trial
data
are
required.

For
cereal
grains,
adequate
residue
data
are
available
for
field
corn
grain,
but
the
field
trial
data
for
grain
from
barley,
sorghum,
and
wheat
are
now
considered
questionable.
However,
adequate
sorghum
grain
(
at
3.8x)
and
wheat
grain
(
at
2.5x)
processing
studies
are
available
and
will
be
used
as
bridging
data.
Trifluralin
residues
were
nondetectable
(<
0.01
pm)
in/
on
sorghum
and
wheat
grain
from
these
exaggerated
rate
studies.
Data
from
the
wheat
grain
processing
study
will
also
be
translated
to
support
a
tolerance
on
barley
grain.

For
the
forage,
fodder
and
straw
of
cereal
grains,
adequate
residue
data
are
available
for
field
corn
forage
and
stover,
but
the
field
trial
data
for
barley,
sorghum,
and
wheat
are
now
considered
questionable.
The
residue
data
from
field
corn
forage
and
stover
will
be
translated
to
support
tolerances
on
sorghum
forage
and
stover.
However,
new
field
trials
must
be
conducted
on
wheat
(
forage,
hay
and
straw)
using
trifluralin
(
EC
and
G)
at
the
maximum
labeled
rates.
The
results
from
the
requested
wheat
field
trails
will
be
translated
to
support
tolerances
on
barley
hay
and
straw.

Although
the
earlier
field
trial
data
on
asparagus
are
not
supported
with
sample
storage
information,
the
recent
asparagus
field
trial
data
will
be
used
as
bridging
data.
Therefore,
no
additional
field
trials
on
asparagus
are
required.

Although
the
existing
field
trial
data
on
peanut
nutmeats
are
questionable,
the
available
peanut
processing
study
will
be
used
as
bridging
data,
as
residues
in/
on
peanuts
were
0.016
ppm
following
an
application
at
5x
maximum
use
rate
for
peanuts.

Similarly,
the
available
sugarcane
and
sunflower
field
trial
data
are
either
questionable
or
limited.
Therefore,
the
sugarcane
and
sunflower
processing
studies
will
be
used
as
bridging
data.
Residues
in/
on
sugarcane
were
nondetectable
(<
0.01
ppm)
following
an
application
at
5x
the
maximum
label
rate,
and
residues
in/
on
sunflower
seed
were
also
nondetectable
(<
0.01
ppm)
following
an
application
at
3x
the
maximum
label
rate.

The
existing
residue
data
on
flax
seed,
safflower
seed,
and
hops
are
also
now
considered
questionable.
However,
the
available
residue
data
for
rapeseed
and
sunflower
will
be
translated
to
support
the
uses
and
tolerances
on
flax
seed
and
safflower;
and
the
available
residue
data
peppermint
and
spearmint
tops
will
be
translated
to
support
the
use
on
hop
vines.

No
residue
data
are
available
depicting
residues
in/
on
rapeseed
forage,
and
the
Agency
does
not
allow
label
restrictions
prohibiting
the
feeding
of
rapeseed
forage.
Therefore,
new
field
trials
are
required
depicting
trifluralin
residues
in/
on
rapeseed
forage
following
application
of
trifluralin
(
EC
and
G)
at
the
maximum
labeled
rates.

Adequate
residue
data
are
also
available
for
aspirated
grain
fractions
derived
from
27
corn
grain,
soybean
seeds,
and
wheat
grain.
These
data
indicate
that
trifluralin
residues
do
not
concentrate
in
aspirated
grain
fractions.
In
addition,
the
Agency
has
also
determined
that
trifluralin
residues
are
not
likely
to
concentrate
on
the
surface
of
sorghum
grain
as
trifluralin
is
applied
early
in
the
growing
season
(
DP
Barcode
D179068,

Therefore,
no
additional
residue
data
on
aspirated
grain
fractions
are
required.

860.1520
Processed
Food
and
Feed
Adequate
processing
studies
have
been
conducted
to
determine
the
concentration,
or
reduction,
of
trifluralin
residues
in
the
processed
commodities
of
the
following
RACs:
field
corn
grain,
cottonseed,
oranges,
peanuts,
potatoes,
sorghum,
soybeans,
sugar
beets,
sugarcane,
sunflower
seed,
and
wheat.
With
the
exception
of
potatoes,
the
data
from
these
studies
indicate
that
trifluralin
residues
do
not
concentrate
in
the
regulated
processed
commodities
derived
from
these
crops.

Potato
processing
studies
indicate
that
residues
of
trifluralin
do
not
concentrate
in
flakes
and
chips,
but
can
concentrate
(
on
average)
by
3x
in
wet
peel
(

0.05
ppm).
The
available
root
and
tuber
vegetable
residue
data
indicate
that
residues
in/
on
potatoes
treated
at
1x
will
be
nondetectable
(<
0.01
ppm);
therefore,
a
separate
tolerance
for
potato
waste
is
not
required
as
any
residues
in/
on
waste
are
likely
to
be
below
the
current
0.05
ppm
tolerance
covering
potatoes.

Processing
studies
are
not
available
on
barley
grain,
flax
seed,
safflower
seed,
and
rapeseed.
However,
data
from
the
wheat
grain
processing
study
will
be
translated
to
barley;
data
from
the
cottonseed
processing
study
will
be
translated
for
flax
seed;
and
data
from
the
sunflower
seed
processing
study
will
be
translated
to
rape
seed
and
safflower
seed.
Based
on
the
translated
data,
tolerances
are
not
required
for
commodities
derived
from
barley
grain,
flax
seed,
rapeseed,
and
safflower.

A
processing
study
is
not
available
for
tomatoes.
However,
adequate
tomato
field
trial
data
are
available
and
demonstrate
nondetectable
residues
of
trifluralin
in/
on
tomatoes
following
treatment
at
exaggerated
application
rates
up
to
4x.
Therefore,
a
tomato
processing
study
is
not
required.

A
processing
study
on
peppermint
and
spearmint
has
been
submitted;
however,
the
residue
data
on
mint
oil
are
not
supported
by
adequate
storage
stability
data.
Therefore,
a
new
mint
processing
study
must
be
conducted.

In
addition,
processing
studies
are
now
required
on
grapes
and
plums.
Previously,
the
Agency
waived
the
requirement
for
these
studies
as
residue
data
for
grapes
and
plums
were
available
from
field
trials
conducted
at
exaggerated
rates,
which
indicated
that
detectable
trifluralin
residues
were
unlikely
to
occur
in
grape
and
plum
processed
fractions.
However,
these
earlier
field
trials
are
no
longer
considered
adequate
due
to
storage

Confined
and
Field
Accumulation
in
Rotational
Crops
A
Confined
Rotational
Crop
Study
for
trifluralin
has
been
reviewed
by
the
Agency,
and,
at
the
time
of
review
was
considered
an
adequate
study.
In
this
study,
total
radioactive
residues
(
TRR)
accumulated
at
a
level
equal
to
or
greater
than
0.01
ppm
in
chard,
turnip
roots
and
tops,
and
corn
forage,
silage,
and
fodder
planted
in
sandy
loam
soil
30
days
after
treatment
(
DAT)
with
[
14C]
trifluralin
applied
at
the
rate
of
0.76­
0.83
lb/
A.
However,
the
residue
of
concern
was
trifluralin
per
se,
and
this
study
indicated
that
residues
of
trifluralin
per
se
in/
on
any
30
DAT
rotational
crop
commodity
would
unlikely
exceed
0.01
ppm,
even
though
the
study
was
conducted
at
less
than
the
maximum
permissible
treatment
rate.
Accumulation
of
14C­
residues
peaked
in
crops
at
30­
day
rotation
and
declined
in
subsequent
rotations.
Based
on
the
results
of
this
study,
the
Agency
did
not
require
a
plant­
back
interval
and
rotational
crop
tolerances
for
trifluralin
residues
were
not
required.

However,
the
HED
Metabolism
Assessment
Review
Committee
concluded
(
meeting
date
2/
4/
04)
that
the
confined
rotational
crop
study
is
not
adequate
by
current
standards
and
a
plant­
back
interval
of
100
days
will
be
required.
If
the
100
day
interval
presents
an
issue
to
users,
a
new
confined
rotational
study
can
be
conducted
at
a
1x
rate
with
a
more
comprehensive
characterization/
identification
of
metabolites.

TOLERANCE
REASSESSMENT
SUMMARY
Tolerances
for
residues
of
trifluralin
in
or
on
raw
agricultural
commodities
are
expressed
as
parent
compound.
Permanent
tolerances
for
trifluralin
residues
have
been
established
on
numerous
plant
commodities
ranging
from
0.05
ppm
in/
on
various
commodities
to
2.0
ppm
in/
on
mung
bean
sprouts
[
40
CFR
§
180.207(
a)].
A
summary
of
the
tolerance
reassessment
and
the
recommended
modifications
in
commodity
definitions
for
trifluralin
is
presented
in
Table
6.

The
available
residue
data
support
the
existing
tolerances
on
the
following
crops/
commodities:
asparagus;
carrot,
roots;
field
corn,
grain,

Tolerance
Modifications:

Available
data
for
alfalfa
hay
reflecting
treatment
at
the
maximum
registered
application
rate
indicate
that
the
established
tolerance
for
residues
of
trifluralin
in/
on
29
alfalfa
hay
should
be
increased
to
2.0
ppm.

Several
of
the
trifluralin
tolerances
established
for
general
crop
groups
are
obsolete
and
should
be
revoked
concomitant
with
establishing
tolerances
on
the
appropriate
crops
and/
or
crop
groups.
The
tolerance
for
"
vegetable,
root
(
exc.
carrots)"
should
be
revoked
concomitant
with
establishing
separate
tolerances
at
0.05
ppm
on
root
and
tuber
vegetables
(
exc,
carrots;
crop
group
1)
and
bulb
vegetables
(
crop
group
3).
The
tolerance
for
"
vegetable,
leafy"
should
be
revoked
concomitant
with
establishing
separate
tolerances
at
0.05
ppm
on
celery,
endive,
leaves
of
root
and
tuber
vegetables
(
crop
group
2),
and
Brassica
leafy
vegetables
(
crop
group
4).
The
tolerance
for
"
vegetables,
seed
and
pod"
should
be
revoked
concomitant
with
establishing
separate
tolerances
at
0.05
ppm
for
okra
and
the
legume
vegetables
(
crop
group
6).
The
tolerance
for
"
legumes,
forage"
should
be
revoked
concomitant
with
establishing
a
tolerance
at
0.05
ppm
for
foliage
of
legume
vegetables
(
crop
group
7),
and
a
separate
tolerance
for
alfalfa
forage
at
3
ppm.

In
addition,
the
established
tolerance
for
"
grain,
crops,
except
corn,
sweet
and
rice
grain"
is
inappropriate.
This
tolerance
should
be
revoked
concomitant
with
establishing
individual
tolerances
at
0.05
ppm
for
barley
grain
and
sorghum
grain.
Separate
(
adequate)
tolerances
of
0.05
ppm
already
exist
for
corn
and
wheat
grain,
and
sorghum
grain
residue
data
are
available
to
support
a
0.05
ppm
tolerance.
Residue
data
on
wheat
grain
will
be
translated
to
support
a
0.05
ppm
tolerance
on
barley
grain.
The
established
tolerance
for
mung
bean
sprouts
should
be
revoked
as
no
registered
uses
exist
for
mung
bean
sprouts
per
se,
and
the
established
tolerance
for
upland
cress
should
be
revoked
as
there
are
no
registered
uses
on
this
crop.

New
Tolerances
Sufficient
data
are
available
to
recommend
establishing
new
tolerances
for
residues
of
trifluralin
at
0.05
ppm
in/
on
almond
hulls,
cotton
gin
byproducts,
and
mustard
seeds.
New
tolerances
will
also
need
to
be
established
for
ruminant
commodities
at
a
level
to
be
determined
by
the
required
feeding
study.

Data
Requirements
Additional
field
trial
data
or
processing
studies
are
required
to
support
existing
tolerances
in/
on
the
following
commodities:
barley,
hay
and
straw;
peppermint,
oil;
rapeseed,
forage;
spearmint,
oil,
and
wheat
forage,
hay,
and
straw.

Based
on
the
available
poultry
metabolism
data,
the
Agency
has
concluded
that
there
is
no
expectation
of
finite
residues
of
trifluralin
in
poultry
commodities.
Therefore,
tolerances
are
not
required
for
eggs
and
fat,
meat,
and
meat
byproducts
of
poultry
at
this
time.
However,
based
on
the
reassessed
tolerance
for
alfalfa
forage
(
3
ppm)
and
hay
(
2
ppm),
the
estimate
of
possible
dietary
exposure
of
trifluralin
to
ruminants
has
30
(
continued;
footnotes
follow)
increased
significantly.
Therefore,
in
order
to
assess
residue
levels
for
tolerances,
new
metabolism
and
feeding
studies
in
ruminants
are
now
being
required.
Once
these
data
are
available,
the
need
for
tolerances
for
trifluralin
in
milk
and
in
fat,
meat,
and
meat
byproducts
of
cattle,
goats,
horses,
and
sheep
will
be
reassessed.
The
Agency
continues
to
expect
that
finite
residues
of
trifluralin
will
not
occur
in
hog
and
poultry
commodities
since
alfalfa
is
not
a
feed
item
for
these
non­
ruminants.
