INTRODUCTION
2,4­
D
[
2,4­
dichlorophenoxyacetic
acid]
is
a
List
A
pesticide
active
ingredient
classified
as
an
herbicide,
a
plant
growth
regulator,
and
a
fungicide.
It
is,
however,
mainly
used
as
a
selective
postemergence
herbicide
for
the
control
of
broadleaf
weed
species
in
a
variety
of
food/
feed
sites
including
field,
fruit,
and
vegetable
crops.
In
addition
to
the
acid
form,
there
are
numerous
salts
and
esters
of
2,4­
D
in
Reregistration
Case
0073,
each
with
an
assigned
PC
Code
number,
that
are
presently
registered
as
active
ingredients
in
end­
use
products
(
EPs).
The
Industry
Task
Force
II
on
2,4­
D
Research
Data
(
Task
Force
II)
is
supporting
the
reregistration
of
2,4­

The
members
of
the
Task
Force
currently
include
Agro­
Gor
Corp
(
jointly
owned
by
Atanor,
S.
A.
and
PBIGordon

Dow
AgroSciences,
and
Nufarm
USA.
In
addition,
USDA's
Interregional
Project
No.
4
(
IR­

is
supporting
the
reregistration
of
a
number
of
minor
crop
uses
for
2,4­
D,
and
the
California
Citrus
Quality
Council
(
CCQC)
is
supporting
selected
uses
of
2,4­
D
isopropyl
ester
(
IPE)
on
citrus
fruits.

2,4­
D
is
currently
registered
by
members
of
Task
Force
II
for
food/
feed
uses
on
a
variety
of
field,
fruit,
and
vegetable
crops
and
aquatic
sites.
The
2,4­
D
formulation
classes
registered
for
food/
feed
uses
include
wettable
powders
(
WP),
granules
(
G),
soluble
concentrates
in
both
liquid
(
SC/
L)
and
solid
(
SC/
S)
forms,
and
emulsifiable
concentrates
(
EC).
These
formulations
are
typically
applied
as
broadcast,
banded,
or
directed
(
spray
or
wiper)
applications
during
dormancy
or
preplant,
preharvest,
preemergence,
emergence,
postemergence,
or
postharvest
using
ground
or
aerial
equipment.

REGULATORY
BACKGROUND
2,4­
D
was
the
subject
of
a
Reregistration
Standard
Guidance
Document
dated
9/
1/
88;
the
Residue
Chemistry
Science
Chapter
of
the
Guidance
Document
was
dated
2/
16/
88.
These
documents
summarized
the
regulatory
conclusions
based
on
available
residue
chemistry
data,
and
specified
the
additional
data
required
for
reregistration
purposes.
Numerous
data
submissions
have
been
received
and
evaluated
since
the
Reregistration
Standard
Guidance
Document.
The
information
2
contained
in
this
document
outlines
the
Residue
Chemistry
Science
Assessments
with
respect
to
the
reregistration
of
2,4­
D.

According
to
the
Agency
publication
entitled
Status
of
Pesticides
in
Registration,
Reregistration,
and
Special
Review
(
EPA
738­
R­
98­
002,
Spring
1998),
2,4­
D
remains
in
pre­
Special
Review
status
because
of
carcinogenicity
concerns.
A
proposed
decision
not
to
initiate
Special
Review
was
published
(
53
FR
9590)
on
3/
23/
88.
The
Task
Force
agreed
to
risk
reduction
measures
on
9/
92
that
included
an
exposure
reduction
plan
effected
through
modifications
of
technical
and
manufacturing
use
product
labels
and
implementation
of
a
user
education
program.
New
rodent
carcinogenicity
data
were
submitted
on
12/
95,
and
following
peer
review
of
these
data,
the
Agency
classified
2,4­
D
as
a
category
D
chemical
[
Not
classifiable
as
to
human
carcinogenicity]
[
TXR
#
0050017].

Tolerances
for
residues
of
2,4­
D
in/
on
plant
and
processed
food/
feed
commodities,
fish,
and
potable
water
are
expressed
in
terms
of
2,4­
D
per
se
[
40
CFR
§
180.142(
a)(
1­
6
and
9­
12)
and
(
b)].
Tolerances
for
residues
in
livestock
commodities
are
currently
established
in
terms
of
residues
2,4­
D
and/
or
its
metabolite
2,4­
dichlorophenol
[
40
CFR
§
180.142(
a)(
8)].
The
HED
Metabolism
Committee
determined
that
2,4­
D
per
se
is
the
residue
of
concern
and
that
tolerances
listed
at
40
CFR
§
180.142
are
to
be
defined
as
"
residues
of
2,4­
D,
both
free
and
conjugated,
determined
as
the
acid"
(
R.
Perfetti,
6/
16/
93;
and
W.
Smith,
12/
10/
93).
The
HED
Metabolism
Assessment
Review
Committee
(
MARC),
at
its
9/
3/
03
meeting,
upheld
this
decision
but
clarified
and
expanded
it
to
specify
that
the
residue
of
concern
for
risk
assessment
and
the
tolerance
expression
is
2,4­
D,
both
free
and
conjugated,
determined
as
the
acid
in
primary
and
rotational
crops,
ruminants,
poultry,
fish
and
shellfish.
Also,
the
residue
of
concern
in
drinking
water
for
risk
assessment
purposes
is
2,4­
D
per
se
(
MARC
Decision
Document
by
W.
Hazel
and
L.
Taylor,
12/
3/
03,
D293119,
TXR
No.
0052264).

The
Food
Quality
Protection
Act
(
FQPA)
of
1996
amended
and
strengthened
the
standard
for
establishing
tolerances
under
the
Federal
Food,
Drug,
and
Cosmetic
Act
(
FFDCA).
All
future
tolerance
petitions
as
well
as
reassessment
of
established
tolerances
must
meet
the

as
amended
by
the
FQPA.
OPP
may
require
additional
data
to
determine
if
the
terms
of
the

are
met.

As
a
result
of
changes
to
Table
1
(
OPPTS
860.1000,
8/
96),
additional
2,4­
D
residue

are
now
required
for
some
commodities
and
other
commodities
have
been
deleted;
any
changes
in
data
requirements
have
been
incorporated
into
this
document.
Any
new
data
requirements
will
be
imposed
at
the
issuance
of
the
2,4­
D
RED
but
should
not
impact
the
reregistration
eligibility
decisions
for
2,4­
D.
If
necessary,
the
dietary

and
risk
will
be
reassessed
upon
receipt
of
the
required
residue

In
addition,
Task

has
provided
the
Agency
with
a
"
Master
Label"
of
2,4­
D
uses
being
supported
by
its
member
companies.
For
each
use
site,
the
Master
Label
generally
summarizes
the
following
information:
forms
of
2,4­
D
being
supported
(
i.
e.
acid,
amine
salts,
and/
or
esters);
types
of
formulations
being
supported
(
i.
e.
EC,
WP,
etc.);
limitations
on
the
type
and
timing
of
5
application(
s);
allowed
application
equipment;
reentry
interval
(
REI);
maximum
single

seasonal
application
rates;
minimum
retreatment
interval
(
RTI);
regional
restrictions;
and
restrictions
on
the
preharvest
and
grazing
intervals
(
PHI
and
PGI).
The
Master
Label
does
not
provide
details
for
uses
on
labels
of
specific
EPs.
The
information
regarding
the
food/
feed
and
aquatic
use
sites
on
the
Master
Label
is
summarized
in
Table
A2.
Agreement
has
been
reached
between
SRRD,
HED,
and
EFED
that
the
use
patterns
summarized
in
the
Master
Label
comprise
the
universe
of
use
patterns
addressed
by
the
2,4­
D
RED
and
all
supporting
documents
[
Memorandum
from
M.
Rice
of
SRRD
to
S.
Abel
(
EFED)
and
M.
Metzger
(
HED)
dated

A
tabular
summary
of
the
residue
chemistry
science
assessments
for
reregistration
of
2,4­
D
is
presented
in
Table
B.
For
purposes
of
evaluating
the
adequacy
of
the
available
residue
chemistry
database
for
2,4­
D
and
reassessing
tolerances,
HED
has
utilized
the
information
in
Table
A2.
When
end­
use
product
DCIs
are
developed
(
e.
g.,
at
issuance
of
the
RED),
RD
should
require
that
all
end­
use
product
labels
(
e.
g.,
MAI
labels,
SLNs,
and
products
subject
to
the
generic
data
exemption)
be
amended
such
that
they
are
consistent
with
use
patterns
listed
in
Table
A2
or
supported
by
end­
use
product­
specific
residue
chemistry
data.

A
review
of
the
food/
feed
crop
uses
listed
in
Table
A2
and
the
supporting
residue
data
indicate
that
the
following
changes
should
be
made
to
all
labels
having
the
designated
uses:

(
i)
directions
for
preharvest
uses
on
citrus
in
the
U.
S.
should
be
restricted
to
AZ
and
CA
and
should
list
a
maximum
use
rate
of
0.27
lb
ae/
A/
crop
cycle;

(
ii)
a
7­
day
PHI
should
be
specified
for
corn
forage
(
all
types);

(
iii)
for
uses
on
stone
fruits,
tree
nuts,
and
pistachios,
the
maximum
single
use
rate
should
be
reduced
to
1.4
lb
ae/
A,
and
the
maximum
seasonal
use
rate
should
be
reduced
to
2.8
lb
ae/
A.

(
iv)
all
labels
bearing
aquatic
uses
should
be
amended
to
indicate
that:
(
a)
all
treated
bodies
of
water
to
be
used
or
likely
to
be
used
as
a
drinking
water
source
must
be
demonstrated
to
contain
2,4­
D
at
<
70
ppb
using
an
approved
assay
after
each
treatment
before
diversion
for
drinking
water
may
occur;
(
b)
the
aquatic
uses
of
2,4­
D
should
be
restricted
to
Federal,
State,
or
local
agencies
or
applicators
under
their
control;
and
(
c)
when
treating
moving
bodies
of
water,
applications
must
be
made
while
traveling
upstream
to
prevent
concentration
of
2,4­
D
downstream
from
the
application.
The
1500­
foot
setback
in
the
Master
Label
is
an
additional,
yet
optional,
restriction
that
may
appear
on
aquatic
use
labels
that
is
expected
to
further
reduce
dietary
exposure
to
2,4­
D
following
direct
aquatic
use.
Task
Force
II
may
choose
to
propose
(
and
support)
a
longer
setback,
if
practical,
that
would
mitigate
risk
to
an
acceptable
level.

In
addition,
HED
notes
that
according
to
the
Master
Label,
the
Task
Force
II
is
not
supporting
the
use
of
2,4­
D
esters
on
pistachios,
filberts,
and
other
tree
nut
crops.
However,
adequate
6
residue
data
are
available
supporting
the
use
of
ester
forms
of
2,4­
D
on
these
crops.
Therefore,
labels
for
the
ester
forms
of
2,4­
D
may
include
use
directions
for
pistachios,
tree
nuts,
and
filberts
(
sucker
control)
if
a
party
is
interested
in
labeling
for
such
uses.

Also,
a
40­
day
PHI
is
presently
being
specified
for
stone
fruits.
However,
the
available
residue
data
indicate
that
residues
are
<
LOQ
(<
0.05
ppm)
at
a
14­
day
posttreatment
interval.
Therefore,
strictly
from
a
residue
chemistry
perspective,
the
PHI
for
stone
fruits
could
be
reduced
to
14
days
without
affecting
the
tolerance
level.

The
supported
use
on
grapes
is
restricted
to
CA
only;
however,
adequate
field
trial
data
reflecting
use
of
2,4­
D
amine
salts
are
available
for
the
entire
U.
S.
Therefore,
labels
for
the
acid
and
amine
salt
forms
of
2,4­
D,
strictly
from
a
residue
chemistry
perspective,
do
not
need
to
restrict
the
use
on
grapes
to
only
CA.

GLN
860.1300:
Nature
of
the
Residue
­
Plants
The
reregistration
requirements
for
plant
metabolism
are
fulfilled.
Adequate
metabolism
studies
are
available
depicting
the
qualitative
nature
of
the
residues
in
three
dissimilar
crops
(
lemon,
potato,
and
wheat).
Based
on
the
available
data,
on
9/
3/
03,
the
MARC
determined
that
the
residue
of
concern
in
plants
for
the
tolerance
expression
and
for
risk
assessment
is
2,4­
D
per
se
in
both
the
free
and
conjugated
forms
(
W.
Hazel
and
L.
Taylor,
12/
3/
03,
D293119,
TXR
No.
0052264).

In
the
lemon
metabolism
study,
[
14C]
2,4­
D
IPE
was
applied
to
lemons
as
a
postharvest
dip
treatment
with
wax
at
500
ppm
for
2
minutes
(
1x
label
rate),
and
lemons
were
sampled
2
hours
to
20
weeks
after
treatment.
Total
radioactive
residues
(
TRR)
ranged
from
2.1
ppm
to
2.8
ppm
and
showed
little
decline
with
storage
at
5
C.
The
parent
compound,
2,4­
D
IPE,
was
rapidly
hydrolyzed,
declining
from
47%
of
the
TRR
at
2
hours
posttreatment
to
0.3%
of
the
TRR
at
2
weeks
posttreatment.
Residues
of
2,4­
D
(
acid)
accounted
for
24%
of
the
TRR
at
2
hours
and
68%
of
the
TRR
at
20
weeks.
Other
minor
metabolites
(
each
<
1%
TRR)
identified
in
lemons
included
2,4­
dichlorophenol
(
2,4­
DCP),
2,5­
dichloro­
4­
hydroxyphenoxyacetic
acid
(
4­
hydroxy­
2,5­
D),
and
2,3­
dichloro­
4­
hydroxyphenoxyacetic
acid
(
4­
hydroxy­
2,3­
D).
Refer
to
table
below
for
structures
of
2,4­
D
and
its
metabolites.

In
the
potato
metabolism
study,
TRR
in
mature
vines
and
tubers
were
6.3
and
0.58
ppm,
respectively,
20
days
following
the
second
of
two
foliar
broadcast
applications
of
[
14C]
2,4­
D
2­
EHE
totaling
0.62
lb
ae/
A
(
4.4x
maximum
labeled
rate).
In
potato
tubers,
solvent
extractable
14Cresidues
accounted
for
>
95%
of
the
TRR.
The
largest
single
component
of
the
extractable
14Cresidues
was
identified
as
2,4­
D
(
43­
46%
TRR);
minor
portions
were

lists
three

(
designated

indicated
that
the
enforcement
methods
currently
listed
in
PAM
Vol.
II
are
unsuitable
for
determining
residues
of
2,4­
D
in
wheat
and

submitted
an

method
for

(
designated
as

which
has
been
independently

Adequate

data
have
been
submitted
and
evaluated
for
the
proposed

method
using
samples
from
the
wheat

study.
The
proposed

method
or
modifications
of
the
enforcement
method
were
used
for
data
collection
purposes.

Livestock
Commodities:
Task

II
submitted
two
separate
(
but
essentially
comparable)
proposed
enforcement
methods
(
GC/
ECD)
for
determination
of
2,4­

in
livestock

Adequate
radiovalidation

have
been
submitted
for
the
method
using
samples
of
fat,
kidney,
and
milk
from
the
goat

study
and
samples
of
eggs
from
the
poultry

study.
The
Agency
concluded
that
the
methods
are
adequate
provided
the
registrants
satisfy
the
following
requests:
(
i)
submit
a
revised
method
which
combines
the
two
methods
into
a
single
method;
(
ii)
delete
from
the
method
all
references
to
the
use
of
diazomethane
as
a
derivatizing
agent;
and
(
iii)
provide
complete
raw
data
and
sample
calculations
(
including
chromatograms
showing
peak
areas,
external
standard
linearity
curves
and
associated
data,
standard
calculations,
etc.).
Once
an
adequate
revised
method
is
received,
HED
will
forward
the
method
to
an
EPA
laboratory
(
BEAD/
ACB)
for
a
tolerance
method
validation.
Recently,
it
has
been
determined
that
the
technology
to
generate
diazomethane
has
advanced
such
that
it
is
no
longer
considered
to
be
a
dangerous
procedure;
as
a
result,
the
use
of
diazomethane
as
a
derivatizing
agent
is
now
considered
acceptable
(

exposed
to

The
maximum

is
10.8
lb
ae/

which
is
equivalent
to
a

Therefore,
the

In

plateaued
within

application
of
the

In
another

respectively,
at
2

and
0.01

one
day
after

0.0015­
1.1

after
4

and
<
0.052

after
7­
14
days,
and
at
reservoir
outlets,
maximum

were
0.015

showed
residues
of
2,4­
D
in
drinking
water
from
the
Fort
Cobb
reservoir
ranging
from
nondetectable
to
0.062
ppm.
The
1992
review
of
the
above
data
concluded
that
rates
of
up
to
40
lb
ae/
A
could
be
extended
to
sites
outside
the
TVA
system,
provided
that
use
is
restricted
to
Federal,
State,
or
local
agencies
or
applicators
under
their
control.
Official
agency
oversight
of
this
aquatic
use
was
deemed
necessary
owing
to
the
relatively
high
2,4­
D
concentrations
in
water
observed
initially
after
treatment
and
the
need
to
control
treatment
and
subsequent
water
uses.
These
data
reflect
the
registered
aquatic

patterns
and
are
adequate
from
a

2,4­
D
treated
water,
the
Agency
tentatively
concluded
that
tolerances
for
irrigated
crops
should
be
established
at
1
ppm
for
all
crop
groups
and
individual
miscellaneous
crops.

However,
the
aquatic
use
patterns
currently
being
supported
by
Task
Force
II
prohibit
the
use
of
2,4­
D
treated
water
for
irrigation
unless
an
approved
assay
indicates
that
2,4­
D
concentrations
are

0.1
ppm.

To
reassess
tolerances
for
irrigated
crops,
a
summary
of
residues
in
various
crops
irrigated
with
2,4­
D
treated
water
is
presented
in
a
table
below.
In
these
studies,
assorted
field
crops
were
irrigated
once
or
twice
with
water
containing
2,4­
D
at
0.02­
5.5
ppm.
Although
a
large
number
of
studies
have
been
conducted,
the
number
of
tests
and
samples
for
a
given
crop
or
commodity
are
limited,
and
no
data
are
available
for
irrigated
perennial
crops.
In
addition,
the
majority
of
the
residue
data
reflect
treatment
with
water
containing
2,4­
D
at
levels
well
above
the
allowed
0.1
ppm
concentration
in
irrigation
water.
Nevertheless,
many
of
the
current
tolerances
in
irrigated
crops
have
been
reassessed.
12
No
residue
data
on
irrigated
crops
are
available
to
support
inadvertent
tolerances
on
avocados,
cottonseed,
citrus
fruits,
pome
fruits,
stone
fruits,
hops,
tree
nuts,
berries
crop
group,
grapes,
and
strawberry.
The
reassessed
tolerance
for
preharvest
plus
postharvest
uses
on
citrus
fruits
(
3.0
ppm),
the
0.2­
ppm
tolerance
in
hops,
and
the
0.2­
ppm
tolerance
in
members
of
the
Tree
Nut
Group
would
readily
cover
any
inadvertent
residues
in
these
crops.
However,
tolerances
based
on
the
primary
uses
of
2,4­
D
on
pome
fruits,
stone
fruits,
blueberry,
grapes,
and
strawberry
are
all
being
reassessed
to
0.05
ppm,
which
is
the
enforcement
method
LOQ.
Although
it
is
unlikely
that
irrigation
with
water
containing
2,4­
D
at

0.1
ppm
would
result
in
residues
>
0.05
ppm
in
these
perennial
crops,
irrigated
crop
field
trials
conducted
on
strawberry
to
represent
perennial
crops
have
been
required
as
confirmatory
data.

Regarding
field
crops,
the
available
irrigated
crop
residue
data
support
tolerances
for
inadvertent
residues
at
0.05
ppm
in/
on
the
following
crop
groups:
bulb
vegetables
(
group
3),
legume
vegetables
(
group
6),
foliage
of
legume
vegetables
(
group
7),
cucurbit
vegetables
(
group
9),
and
fruiting
vegetables
(
group
8).
Treatment
of
cucumbers,
bell
peppers,
beans,
onions,
and
soybeans
with
irrigation
water
containing
2,4­
D
at
up
to
5.5
ppm
resulted
in
residues

0.05
ppm
in/
on
RACs
of
these
crops.
The
irrigated
crop
data
support
inadvertent
tolerances
of
0.2
ppm
in
alfalfa
and
sorghum
RACs
and
0.4
ppm
in
lettuce
and
potato.

In
addition,
tolerances
resulting
from
the
primary
use
of
2,4­
D
on
corn
(
field,
pop­,
and
sweet)
and
grasses
are
high
enough
to
cover
any
inadvertent
residues
in
these
crops
resulting
from
irrigation
with
water
containing
2,4­
D.

However,
irrigated
crop
residue
data
(
see
table
below)
are
equivocal
from
trials
on
sugar
beets.
As
a
result,
the
appropriate
tolerance
for
the
root
and
tuber
vegetables
group
represented
by
this
crop
(
as
well
as
potato
at
0.2
ppm)
cannot
be
determined
based
on
the
available
residue
data.

To
support
tolerances
for
inadvertent
residues
of
2,4­
D
in/
on
irrigated
crops,
additional
residue
data
are
required
on
sugar
beet
roots
and
tops
to
represent
field
crops
from
the
root
and
tuber
vegetable
crop
group
and
the
foliage
of
root
and
tuber
vegetable
crop
group.
To
support
tolerances
in
irrigated
perennial
crops,
residue
data
are
also
required
on
strawberry.
The
crops
should
be
irrigated
with
water
containing
2,4­
D
at
0.1
ppm.

Prior
to
conducting
field
trials
on
irrigated
crops,
the
registrants
are
encouraged
to
submit
the
protocols
for
these
studies
to
the
Agency
for
review.

range
from
0.02

The
submitted
cattle
feeding
study
is
adequate.
Four
groups
of
three
cows
each
were
dosed
orally
with
2,4­
D
at
nominal
rates
of
1500,
3000,
6000,
and
9000
ppm
for
28­
30
days,
equivalent
to
1.7,
3.4,
6.9,
and
10.2x
the
MTDB
for
cattle,
and
were
sacrificed
within
20
hours
of
the
final
dose.
Two
additional
groups
of
cows
were
dosed
at
the
highest
level
(
10.2x)
and
sacrificed
3
or
7
days
after
the
cessation
of
dosing.
Milk,
liver,
kidneys,
composite
muscle
(
round
and
tenderloin),
and
composite
fat
(
perirenal
and
omental)
were
collected.

Residues
in
milk
plateaued
after
7­
11
days
of
dosing.
Maximum
residues
were
0.07
ppm
at
the
low
dose
level
(
1.7x)
and
increased
linearly
(
r2=
0.994)
with
increasing
dose.
At
the
3.4x,
6.9x,
and
10.3x
dose
levels,
maximum
milk
residues
were
0.18,
0.58,
and
0.87
ppm,
respectively.
After
the
3­
and
7­
day
depuration
periods,
residues
in
milk
from
the
10.2x
dose
group
declined
to
<
0.01­
0.02
ppm.

Immediately
following
dosing
(
0­
day
PSI),
maximum
residues
at
the
lowest
dose
level
(
1.7x)
were
0.20
ppm
in
liver,
6.48
ppm
in
kidney,
0.24
ppm
in
muscle,
and
0.51
ppm
in
fat.
Maximum
residues
at
the
highest
dose
level
(
10.2x)
were
3.80
ppm
in
liver,
24.4
ppm
in
kidney,
1.02
ppm
in
muscle,
and
2.30
ppm
in
fat.
After
a
3­
day
depuration
from
dosing
at
10.2x,
residues
declined
to
0.67
ppm
in
liver,
0.1
ppm
in
kidney,
0.06
ppm
in
muscle,
and
0.12
ppm
in
fat.
After
a
7­
day
depuration
period,
residues
were
0.51
ppm
in
liver
and
<
0.05
ppm
in
kidney,
muscle,
and
fat.
HED
notes
that
2,4­
D
is
excreted
rapidly,
as
evidenced
by
the
residue
decline
in
tissues
from
the
high­
dose
animals
following
a
withdrawal
period.
Based
on
residues
on
the
last
day
of
dosing
in
feeding
studies,
the
2,4­
D
tolerance
in
milk
may
be
reduced
from
0.1
ppm
to
0.05
ppm
whereas
the
2.0­
ppm
tolerance
in
kidney
should
be
reassessed
at
4.0
ppm
and
the
0.2­
ppm
tolerances
in
meat,
fat,
and
meat
byproducts
except
kidney
(
of
cattle,
goats,
horses,
and
sheep)
should
be
reassessed
at
0.3
ppm.
A
3­
day
grass
grazing
restriction
was
assumed
to
estimate
the
reassessed
tolerance
for
2,4­
D
residues
in
milk;
this
is
considered
to
be
practical
and
enforceable
because
dairy
cattle
are
typically
grazed
in
fenced
pastures
for
which
there
is
a
high
level
of
farmer
control.
A
grazing
restriction
is
not
practical
or
enforceable
for
beef
catte;
therefore,
a
0­
day
grazing
restriction
was
assumed
to
reassess
2,4­
D
tolerances
in
meat,
fat,
and
meat
byproducts.
16
The
reregistration
requirements
for
studies
pertaining
to
magnitude
of
the
residue
in
poultry
tissues
and
eggs
are
waived.
Based
on
the
results
of
2,4­
D
poultry
metabolism
study,
there
is
no
reasonable
expectation
of
finite
residues
in
poultry
tissues
and
eggs
[
Category
3
of
40
CFR
§
180.6(
a)(
3)]
when
2,4­
D
is
applied
according
to
registered
use
directions.
Therefore,
tolerances
for
residues
of
2,4­
D
in
poultry
commodities
are
not
needed
and
should
be
revoked.
In
addition,
as
the
lowest
feeding
level
for
cattle
was

940x
the
MTDB
for
swine,
the
maximum
expected
residues
in
hog
tissues
would
be
0.007
ppm
(
kidney).
Accordingly,
tolerances
for
residues
in
hog
commodities
are
not
needed
and
should
be
revoked.

GLN
860.1500:
Crop
Field
Trials
For
purposes
of
establishing
new
tolerances,
HED
has
determined
that
the
three
classes
of
2,4­
D
derivatives
represented
in
end­
use
products
(
acid,
amine
salts,
and
esters)
are
not
equivalent
(
DP
Barcode
D258633,
8/
11/
99,
D.
Miller).
Residue
data
are
required
on
each
derivative
class
registered
for
use
on
a
crop,
and
translation
of
residue
data
is
allowed
only
within
a
given
class
(
e.
g.
amine
salt
to
amine
salt
or
ester
to
ester).
However,
the
available
residue
data
for
the
amine
salt
and
ester
forms
will
be
used
to
support
the
existing
registrations
for
the
acid,
amine
salt
(
including
DMA,
TIPA,
IPA,
and
DEA)
and
ester
(
2­
EHE
and
BEE)
forms
of
2,4­
D
on
crops
with
existing
tolerances.

For
any
future
uses
or
registrations
on
new
crops
where
both
amine
salt
and
ester
forms
are
to
be
registered,
residue
data
should
be
generated
with
both
an
amine
salt
and
ester
form
of
2,4­
D
in
sideby
side
field
trials.
If
the
acid
form
is
to
be
registered
in
addition
to
any
amine
salt
and/
or
ester
forms,
the
amine
salt
and/
or
ester
field
trial
results
can
be
translated
to
the
acid.
Otherwise
(
if
only
the
acid
form
is
to
be
registered),
residue
field
trials
should
be
performed
with
the
acid.

Quality
Council
(
CCQC)
are
listed
in
Table
A2
as
provided
in
Task
Force
II's
Master
Label.
For
purposes
of
reregistration
and
tolerance
reassessment,
the
adequacy
of
the
existing
crop
field
trials
will
be
assessed
by
comparison
against
the
use
patterns
in
the
Master
Label;
this
has
been
agreed
to
by
SRRD
(
M.
Rice,
3/
18/
03).

Adequate
crop
field
trials
are
available
for
the
following
raw
agricultural
commodities
(
RACs):
almonds
and
almond
hulls;
apples;
asparagus;
aspirated
grain
fractions
(
corn
and
wheat
grain);
blueberries;
cherries;
corn
(
field)
grain,
forage,
and
stover;
corn
(
sweet)
K+
CWHR;
cranberries;
filberts;
grapes;
grapefruit
(
pre­
harvest);
grass
forage
and
hay;
hops,
lemons
(
pre­
and
post­
harvest);
oranges
(
pre
and
post­
harvest);
peaches;
pears;
pecans;
pistachios,
plums/
fresh
prunes;
potatoes;
rice
grain
and
straw;
wild
rice
grain;
sorghum
grain,
forage,
and
stover;
soybean
forage,
hay,
and
seeds;
strawberries;
sugarcane;
and
wheat
grain,
forage,
and
straw.

Residue
data
on
aspirated
grain
fractions
from
field
corn
and
wheat
will
be
sufficient
to
support
the
tolerance
for
aspirated
grain
fractions
as
the
uses
on
soybean
and
sorghum
are
pre­
plant
or
early
17
season
uses
that
are
unlikely
to
result
in
residues
on
the
outer
surfaces
of
the
harvested
soybeans
or
sorghum
grain.

Separate
residue
data
on
sweet
corn
forage
and
stover
are
not
required
as
the
use
on
sweet
corn
is
similar
to
field
corn
except
that
the
PHI
for
sweet
corn
is
much
longer
(
45
days)
than
for
field
corn
(
7
days).
Therefore,
the
residue
data
on
field
corn
forage
and
stover
will
also
be
used
to
conservatively
support
tolerances
in
sweet
corn
forage
and
stover.

Although
no
data
are
available
supporting
the
postharvest
use
of
2,4­
D
in/
on
grapefruit
imported
into
the
U.
S.,
none
are
required
as
postharvest
residue
data
are
available
for
lemons
and
oranges
depicting
this
use.
Given
the
surface
to
volume
ratios
of
these
fruits,
2,4­
D
residues
in/
on
grapefruit
are
unlikely
to
exceed
the
residues
observed
in
lemons
and
oranges
resulting
from
a
postharvest
use.

The
Task
Force
II
has
indicated
that
it
will
not
be
supporting
the
use
of
the
2,4­
D
esters
on
filberts
(
sucker
control),
pistachios,
and
other
tree
nut
crops.
However,
adequate
residue
data
are
available
supporting
the
use
of
2,4­
D
esters
on
these
crops.
Accordingly,
use
directions
for
ester
forms
could
include
these
uses.

The
supported
use
directions
for
stone
fruit,
tree
nut
and
pistachio
orchards
specify
maximum
single
and
seasonal
rates
of
2
and
4
lb
ae/
A,
respectively.
However,
the
available
almond,
pecan,
pistachio,
cherry,
peach,
and
plum
data
only
support
a
maximum
single
application
rate
of
1.4
lb
ae/
A
and
a
maximum
seasonal
rate
of
2.8
lb
ae/
A.

Residue
data
from
the
available
wheat
field
trials
on
grain,
forage,
and
straw
will
be
translated
to
support
tolerances
for
residues
in
the
same
commodities
of
barley,
millet,
oats,
and
rye.

Residue
data
remain
outstanding
on
wheat
hay.
Data
depicting
residues
in/
on
wheat
hay
following
a
single
application
at
1.25
lb
ae/
A
are
required
from
a
total
of
20
trials,
each
including
side­
by­
side
tests
of
an
amine
salt
and
ester
form
of
2,4­
D.
In
addition,
a
PHI
should
be
proposed
for
wheat
hay.
Wheat
hay
data
will
be
translated
to
the
hay
of
barley,
millet,
and
oats.

The
available
residue
data
on
grapefruit,
lemon
and
citrus
are
adequate
to
support
the
preharvest
use
of
2,4­
D
IPE
only
on
citrus
fruits
grown
in
Region
10,
which
includes
production
areas
in
AZ
and
CA.
Therefore,
the
labels
should
be
amended
to
restrict
this
use
to
these
states.
However,
a
regional
restriction
on
the
postharvest
use
on
lemons
is
not
necessary
from
a
residue
chemistry
perspective.

The
supported
use
on
grapes
restricts
the
use
to
only
CA.
However,
sufficient
grape
field
trial
data
are
available
to
support
the
use
on
grapes
throughout
the
U.
S.

The
reregistration
requirements
for
magnitude
of
the
residue
in
the
processed
commodities
of
the
following
crops
have
been
fulfilled:
apples,
barley,
citrus
fruits,
corn,
oats,
potatoes,
plum/
prunes,
rice,
rye,
sorghum,
soybeans,
sugarcane,
and
wheat.
Residues
of
2,4­
D
did
not
concentrate
in
any
regulated
processed
commodities
derived
from
apple,
corn
grain,
plum/
prunes,
and
sorghum
grain.
However,
concentration
of
residues
was
observed
in
regulated
commodities
processed
from
citrus
fruits,
sugarcane,
and
wheat
grain.

The
available
lemon
processing
study
indicates
that
2,4­
D
residues
do
not
concentrate
in
citrus
oil
or
juice,
but
can
concentrate
by
4.6x
in
dried
pulp
derived
from
treated
fruit.
Based
on
HAFT
residues
of
0.487
ppm
from
the
recent
postharvest
treatment
trials
using
lemons
and
oranges,
the
maximum
expected
residues
in
citrus
dried
pulp
would
be
2.24
ppm.
As
this
is
below
the
reassessed
3.0
ppm
tolerance
for
citrus
fruits,
a
separate
tolerance
for
dried
citrus
pulp
is
not
required.
Additionally,
it
is
expected
that
citrus
intended
for
the
fresh
market
is
much
more
likely
to
be
treated
postharvest
than
fruit
for
processing.

The
available
rice
processing
study
indicates
that
2,4­
D
residues
do
not
concentrate
in
rice
bran
and
polished
rice,
but
can
concentrate
by
3.3x
in
hulls
derived
from
treated
rice
grain.
Based
on
HAFT
residues
of
0.425
ppm
in/
on
rice
grain,
the
maximum
expected
residues
in
hulls
would
be
1.4
ppm,
which
supports
a
2.0
ppm
tolerance
for
rice,
hulls.

For
sugarcane,
the
available
processing
studies
indicate
that
2,4­
D
residues
do
not
concentrate
in
refined
sugar,
but
can
concentrate
by
7x
in
molasses
derived
from
treated
sugarcane.
Based
on
HAFT
residues
of
0.015
ppm
in
cane,
the
maximum
expected
residues
in
molasses
would
be
0.105
ppm,
which
supports
a
0.20
ppm
tolerance
in
sugarcane
molasses.

The
available
wheat
processing
study
indicates
that
2,4­
D
residues
do
not
concentrate
in
wheat
flour,
middlings,
or
shorts,
but
can
concentrate
by
3.6x
in
bran
derived
from
treated
grain.
Based
on
HAFT
residues
of
1.08
ppm
in
wheat
grain,
the
maximum
expected
residues
in
bran
would
be
3.88
ppm,
which
supports
a
4.0
ppm
tolerance
in
wheat,
bran.
Data
from
the
wheat
processing
study
will
be
translated
to
oats,
barley,
rye,
and
millet
and
will
support
4.0
ppm
tolerances
for
residues
in
barley
and
rye
bran.

Although
a
potato
processing
study
for
2,4­
D
is
not
available,
the
use
of
2,4­
D
on
potatoes
is
for
enhancing
the
red
color
and
storage
retention
of
red
potatoes
and
is
restricted
to
potatoes
grown
for
"
Fresh
market
only."
As
most
processing
potatoes
are
grown
under
contract
with
the
processor,
who
specifies
the
varieties
and
pesticides
that
can
be
used,
the
label
language
restricting
use
to
fresh
market
potatoes
is
acceptable
for
this
use
of
2,4­
D
(
B.
Schneider,
personal
communication,
6/
5/
03).
Therefore,
the
Agency
will
waive
the
requirement
for
a
potato
processing
study.

A
processing
study
on
soybeans
is
also
not
currently
required
as
2,4­
D
residues
were
<
0.01
ppm
in/
on
all
soybean
seed
samples
harvested
at
maturity
from
seven
tests
in
which
2,4­
D
(
acid,
amine
salt,
and
ester)
was
applied
as
a
preplant
treatment
at
2.8x
the
maximum
label
rate.

Confined/
Field
Accumulation
in
Rotational
Crops
The
reregistration
requirements
for
confined/
field
rotational
crop
studies
are
fulfilled.
The
available
confined
rotational
crop
data
(
summarized
below)
indicate
that
additional
field
trials
are
not
required.
In
addition,
no
rotational
crop
tolerances
are
necessary,
and
no
plantback
intervals
following
2,4­
D
application
are
needed.

Radioactive
residues
in
lettuce,
radishes,
and
wheat
were
<
0.001­
0.06
ppm
and
0.01­
0.084
ppm
from
plantings
made
30
and
139
days,
respectively,
following
an
application
of
[
14C]
2,4­
D
to
a
sandy
loam
soil
at
2.17
lb
ae/
A
(
1.1x
the
maximum
label
rate).
Radioactive
residues
were
adequately
characterized
in
all
crop
matrices.
The
majority
of
the
14C­
residues
were
characterized
as
either
aqueous
soluble
or
unextractable
and
reflected
the
incorporation
of
radioactivity
into
natural
components.
In
wheat
grain,
radioactivity
incorporated
into
starch
accounted
for
69­
81%
of
the
TRR,
and
6­
34.6%
of
the
TRR
was
associated
with
isolated
cellulose
and
lignin
fractions
from
lettuce,
radish
tops,
and
wheat
straw
from
the
30­
day
PBI
and
wheat
forage
and
straw
from
the
139­
day
PBI.
Acidic
organic
fractions,
which
would
have
contained
2,4­
D
residues,
were

0.004
ppm
in
all
matrices
from
both
PBIs
following
either
direct
solvent
extraction
or
acid
hydrolysis
and
solvent
extraction.
Aqueous
EtOH
soluble
residues
were
0.003­
0.017
ppm,
and
were
only
>
0.01
ppm
in
radish
tops
(
30­
day
PBI)
and
wheat
straw
(
30­
and
139­
day
PBIs).
Organosoluble
residues
released
by
hydrolysis
of
solvent
extracted
solids
also
accounted
for
minor
amounts
of
radioactivity
(<
10%
TRR
and
<
0.01
ppm).
The
only
metabolites
detected
in
any
matrix
were
2,4­
D
and
2,4­
dichloroanisole,
which
were
each
detected
at
0.0005
ppm
following
acid
hydrolysis
of
EtOH/
H
2
O­
soluble
residues
from
radish

Separate
residue
data
on
sweet
corn
forage
and
stover
are
not
required
as
the
use
on
sweet
corn
is
similar
to
field
corn
except
that
the
PHI
for
sweet
corn
is
much
longer
(
45
days)
than
for
field
corn
(
7
days).
Therefore,
the
residue
data
on
field

will
also
be
used
to
conservatively
support
tolerances
in
sweet
corn

TOLERANCE
REASSESSMENT
SUMMARY
Tolerances
for
residues
of
2,4­
D
in/
on
plant
RACs
and
processed
commodities,
fish,
and
potable
water
are
currently
expressed
in
terms
of
2,4­
D
per
se
[
40
CFR
§
180.142(
a)(
1­
6
and
9­
12)
and
(
b)].
Tolerances
for
residues
in
livestock
commodities
are
currently
expressed
in
terms
of
2,4­
D
and/
or
its
metabolite
2,4­
dichlorophenol
(
2,4­
DCP)
[
40
CFR
§
180.142(
a)(
8)].

The
MARC
has
concluded
that
2,4­
D
is
the
residue
of
concern
and
that
tolerances
listed
in
40
CFR
§
180.142
are
to
be
defined
as
residues
of
2,4­
D,
both
free
and
conjugated,
determined
as
the
acid
(
W.
Hazel
and
L.
Taylor,

TXR
No.

HED
notes
that
there
are
a
number
of
separate
active
ingredients
in
2,4­
D
Reregistration
Case
No.
0073.
These
are
2,4­
D
in
the
acid
form
as
well
as
the
sodium
salt,
four
amine
salts,
and
three
esters
(
see
Table
A1).
Upon
contact
with
water
and/
or
hydrolytic
enzymes,
all
of
these
forms
are
converted
to
a
single
common
moiety
(
2,4­
D
anion
or
acid
depending
on
pH)
that
is
the
pesticidally­
active
component
serving
as
the
basis
for
tolerance
regulation
(
i.
e.,
2,4­
D
acid).
As
the
available
tolerance
enforcement
methodology
cannot
distinguish
between
which
form
of
the
pesticidally
active
component
was
applied,
HED
recommends
that
the
tolerance
definition
at
CFR
§
180.142
be
revised
to
remove
all
references
to
the
specific
form
of
the
active
ingredient
applied.
We
note
that
most
of
the
salts
and
esters
listed
at
180.142
no
longer
serve
as
active
ingredients
in
a
registered
pesticide
product.
Also,
new
salt
and
ester
forms
of
2,4­
D
may
be
registered
as
active
ingredients
in
the
future.
Language
similar
to
the
following
is
recommended
for
the
2,4­
D
tolerance
expression
at
180.142(
a)
to
cover
applications
of
the
various
forms
of
the
pesticidally
active
component:

"
Tolerances
are
established
for
residues
of
the
herbicide,
plant
growth
regulator,
and
fungicide
2,4­
D
(
2,4­
dichlorophenoxyacetic
acid),
both
free
and
conjugated,
determined
as
the
acid,
in
or
on
the
raw
agricultural
commodities
and
processed
products
listed
below
resulting
from
the
preharvest
and/
or
postharvest
application
of
2,4­
D
or
its
various
salts
and
esters.
A
(
generally
small)
portion
of
the
2,4­
D
residues
comprising
these
tolerances
may
also
be
contributed
inadvertently
by
the
use
of
treated
irrigation
water
during
the
crop
growing
season."

The
listing
for
2,4­
D
tolerances
in
40
CFR
§
180.142
should
be
recodified
into
parts
(
a),
(
b),
(
c),
and
(
d).
Part
(
a)
should
be
reserved
for
commodities
with
permanent
tolerances
reflecting
at
least
a
preharvest
(
field)
or
postharvest
use,
part
(
b)
for
Section
18
emergency
exemptions,
part
(
c)
for
tolerances
with
regional
registrations,
and
part
(
d)
for
commodities
bearing
2,4­
D
residues
solely
inadvertently,
including
irrigated
crops.
A
summary
of
2,4­
D
tolerance
reassessments
and
recommended
recodifications
is
presented
in
Table
C
along
with
any
recommended
changes
in
commodity
definitions.

Note
that
some
commodities
currently
are
the
subject
of
two
or
more
separate
tolerances
depending
on
the
use
pattern,
the
2,4­
D
form
applied,
timing
of
treatment
(
preharvest
or
postharvest),
or
37
degree
of
intent
to
deposit
residues
(
direct
treatment
or
inadvertent).
Direct
treatment
involves
intentional
field
treatment
of
crop
sites
or
postharvest
treatment
of
harvested
commodities
on
registered
labels.
Inadvertent
deposition
involves
the
incidental
exposure
of
crops
when
water
passing
through
2,4­
D­
treated
irrigation
ditchbanks
or
diverted
from
2,4­
D­
treated
bodies
of
water
is
used
to
irrigate
crops.
HED
is
proposing
to
remove
most
such
use­
pattern
or
FIFRA­
related
language
at
180.142.
Due
to
the
complicated
nature
of
the
routes
of
residue
deposition,
we
are
proposing
to
subsume
the
lower
tolerances
in
the
highest
existing
or
reassessed
tolerance
established
in
the
same
commodity
­
even
if
that
results
in
180.142(
a)
containing
some
tolerances
that
reflect
2,4­
D
residues
that
could
potentially
result
from
two
or
more
exposure
routes.
An
example
is
citrus
which
has
tolerances
for
2,4­
D
in
the
RAC
resulting
from
preharvest
use
+
postharvest
use,
irrigation
ditchbank
treatment
(
inadvertent),
and
direct
water
body
treatment
(
also
inadvertent).
If
there
are
no
registered
uses
on
a
given
commodity
and
residues
are
likely
to
occur
on
that
commodity
solely
inadvertently,
i.
e.,
via
irrigation,
then
the
tolerance
in
that
commodity
will
be
located
under
180.142(
d).
In
most
cases,
residues,
and
hence
the
tolerance,
resulting
from
a
direct,
registered
use
are
higher
than
the
residues
(
and
the
tolerance)
resulting
inadvertently.
HED
proposes
these
revisions
because
we
know
that
an
enforcement
agency,
having
detected
2,4­
D
residues
in
a
commodity,
would:
(
i)
not
be
able
to
distinguish
which
form
of
2,4­
D
had
been
applied;
(
ii)
rarely
be
able
to
determine
who
applied
the
pesticide,
when,
or
for
what
purpose;
and
(
iii)
not
know
whether
a
sample
is
violative
if
the
2,4­
D
concentration
falls
between
two
tolerance
levels.

Tolerances
Listed
Under
40
CFR
§
180.142(
a)(
1):

Adequate
data
are
available
to
reassess
the
established
tolerances
for
the
following
commodities:
apple,
apricot,
citrus
fruit,
pear,
potato
and
quince.

The
available
apple
and
pear
residue
data
will
support
a
crop
group
tolerance
at
0.05
ppm
for
pome
fruits
under
the
redesignated
section
180.142(
a).
The
separate
tolerances
on
apple,
pear,
and
quince
should
be
revoked
concomitant
with
establishing
a
new
pome
fruit
crop
group
tolerance.

The
5
ppm
tolerance
on
citrus
fruits
should
be
reassessed
to
3.0
ppm
to
reflect
any
combination
of
the
preharvest
use
on
citrus,
the
postharvest
use
of
2,4­
D
on
lemons
in
the
U.
S.,
a
similar
postharvest
use
on
oranges
imported
into
the
U.
S.,
and
any
inadvertent
(
irrigation)
residues
that
may
be
incurred
as
a
result
of
2,4­
D
use
in
aquatic
sites.
The
tolerances
in
citrus
fruit
of
0.1
ppm
at
180.142(
a)(
3)
and
1.0
ppm
at
180.142(
a)(
6),
both
reflecting
inadvertent
residues,
should
be
revoked
as
they
will
be
subsumed
by
the
reassessed
tolerance
of
3.0
ppm
at
180.142(
a).
Perhaps
a
subsection,
eg.,
180.142(
a)(
i)
could
note
that
the
citrus
fruit
group
tolerance
may
include
residues
resulting
from
preharvest
use
of
2,4­
D
in
citrus
orchards
restricted
to
AZ
and
CA.

The
tolerance
for
residues
in/
on
apricots
should
be
revoked
as
residues
in/
on
apricots
will
be
covered
by
the
tolerance
in
stone
fruits.
38
Tolerances
Listed
Under
40
CFR
§
180.142(
a)(
2):

Adequate
data
are
available
to
reassess
all
the
tolerances
listed
under
180.142(
a)(
2).
All
reassessed
tolerances
should
be
recodified
under
the
revised
section
180.142(
a).

Based
on
the
available
residue
data,
the
current
tolerances
on
grass
hay
and
tree
nuts
are
adequate.
However,
tolerances
can
be
lowered
on
the
following
commodities:
blueberry,
sweet
corn
(
kernel
plus
cob
with
husks
removed),
corn
forage
and
grain,
cranberry,
stone
fruits,
grape,
grass
forage,
pistachio,
rice
straw,
sorghum
forage,
grain
and
stover,
and
sugarcane.
Tolerances
should
be
increased
on
the
following
commodities:
corn
stover,
rice
grain,
and
wheat
grain
and
forage.

The
available
residue
data
for
wheat
commodities
will
be
used
to
reassess
tolerances
on
similar
commodities
from
barley,
millet,
oats,
and
rye.
Tolerances
should
be
increased
accordingly
on:
barley
grain;
millet
grain,
forage
and
straw;
oat
forage
and
grain;
and
rye
forage
and
grain.

The
tolerance
for
residues
in
sugarcane
forage
should
be
revoked
because
it
is
no
longer
considered
a
significant
livestock
feed
item
and
has
been
deleted
from
Table
1
(
OPPTS
GLN
860.1000).

Tolerances
Listed
Under
40
CFR
§
180.142(
a)(
3):

Tolerances
listed
in
40
CFR
§
180.142(
a)(
3)
are
established
for
negligible
residues
of
2,4­
D
in
irrigated
crops
from
application
of
its
dimethylamine
salt
to
irrigation
ditch
banks
in
the
Western
United
States
in
programs
of
the
Bureau
of
Reclamation,
U.

Agricultural
Research
Service,
U.
S.
Department
of
Agriculture;
and
the
Corps
of
Engineers,
U.
S.
Department
of
Defense.
Where
tolerances
are
established
at
higher
levels
resulting
from
other
uses
of
2,4­
D,
the
higher
tolerance
applies
also
to
residues
in
crops
from
the
irrigation
ditch
bank
use
cited
in
this
paragraph.

The
tolerances
in
crops
or
crop
groups
listed
under
40
CFR
§
180.142(
a)(
3)
that
do
not
have
a
direct
treatment
tolerance
under
180.142(
a)
should
be
recodified
as
180.142(
d),
i.
e.,
inadvertent
residue
tolerances.

The
available
irrigated
crop
data
support
tolerances
for
inadvertent
residues
at
0.2
ppm
in
foliage
of
legume
vegetables
(
group
7)
and
nongrass
animal
feed
(
group
18)
and
at
0.05
ppm
in/
on
the
following
crops
groups:
bulb
vegetables
(
group
3),
legume
vegetables
(
group
6),
cucurbit
vegetables
(
group
9),
and
fruiting
vegetables
(
group
8).

In
addition,
tolerances
resulting
from
the
primary
use
of
2,4­
D
on
grasses,
citrus
fruits,
and
tree
nuts
are
high
enough
to
cover
any
inadvertent
residues
in
these
crops
that
may
result
from
the
use
of
2,4­
D
treated
irrigation
water.
Therefore,
separate
tolerances
for
inadvertent
residues
in/
on
these
crops
are
not
required
and
would
be
superfluous.
39
Separate
tolerances
for
inadvertent
residues
are
unnecessary
in
pome
fruits,
stone
fruits,
pistachios,
grapes,
blueberry,
and
strawberry
as
these
crops
all
have
tolerances
resulting
from
the
direct
use
of
2,4­
D.
However,
the
tolerances
in
all
of
these
commodities
have
been
reassessed
at
0.05
ppm,
the
LOQ
of
the
enforcement
method,
to
reflect
only
direct
treatment
at
this
time.
It
is
reasonably
possible
that
inadvertent
residues
resulting
from
irrigation
with
treated
water
could
contribute
concentrations
of
2,4­
D
in
the
commodities
necessitating
tolerances
higher
than
0.05
ppm.
Therefore,
confirmatory
irrigated
crop
residue
data
are
required
for
representative
perennial
crops
(
grape,
an
orchard
fruit,
and
strawberry).
The
field
trial
data
on
irrigated
grapes
will
be
used
to
determine
an
appropriate
contributing
inadvertent
residue
level
in
berries,
and
field
trial
data
on
an
irrigated
tree
fruit
(
e.
g.
apples)
will
be
used
to
determine
an
appropriate
contributing
inadvertent
residue
level
in
all
orchard
crops
having
reassessed
direct­
treatment
tolerances
at
0.05
ppm
under
the
revised
180.142(
a)
as
well
as
the
appropriate
inadvertent
tolerance
in
avocados
under
180.142(
d).
Also,
additional
residue
data
on
sugar
beets
and
tops
irrigated
with
water
containing
2,4­
D
at
0.1
ppm
are
required
to
permit
reassessment
of
the
tolerances
in
the
Root
and
Tuber
Vegetables
Group
and
the
Leaves
of
Root
and
Tuber
Vegetables
Group
resulting
inadvertently
due
to
irrigation
with
2,4­
D­
treated
water.
These
data
may
also
be
used
to
reassess
inadvertent
tolerances
established
at
180.142(
d)
as
a
result
of
the
2,4­
D
RED.

CODEX
HARMONIZATION
The
Codex
Alimentarius
Commission
has
established
several
maximum
residue
limits
(
MRLs)
for
residues
of
2,4­
D
in/
on
various
plant
and
animal
commodities.
The
Codex
MRLs
are
expressed
in
terms
of
2,4­
D
per
se.
The
expression
of
residues
for
Codex
MRLs
and
U.
S.
tolerances
is
harmonized.
A
numerical
comparison
of
the
Codex
MRLs
and
the
corresponding
reassessed
U.
S.
tolerances
is
presented
in
Table
D.
