BRIEF
SUMMARY
OF
THE
NEED
FOR
METHYL
BROMIDE
AS
A
CRITICAL
USE
Currently
registered
alternatives
to
methyl
bromide
do
not
consistently
provide
effective
control
of
nutsedge
weed
species
and
more
time
is
needed
to
evaluate
relationship
between
fumigant
alternatives,
various
mulches,
and
herbicide
systems
under
different
growing
conditions.

The
US
nomination
is
only
for
those
areas
where
the
alternatives
are
not
suitable.
In
US
tomato
production
there
are
several
factors
that
make
the
potential
alternatives
to
methyl
bromide
unsuitable.
These
include:
­
pest
control
efficacy
of
alternatives:
the
efficacy
of
alternatives
may
not
be
comparable
to
methyl
bromide
in
some
areas,
making
these
alternatives
technically
and/
or
economically
infeasible
for
use
in
tomato
production.
­
geographic
distribution
of
key
target
pests:
i.
e.,
some
alternatives
may
be
comparable
to
methyl
bromide
as
long
as
key
pests
occur
at
low
pressure,
and
in
such
cases
the
US
is
only
nominating
a
CUE
for
tomato
where
the
key
pest
pressure
is
moderate
to
high
such
as
nutsedge
in
the
Southeastern
US.
­
regulatory
constraints:
e.
g.,
telone
use
is
limited
in
California
due
to
townships
caps
and
in
Florida
due
to
the
presence
of
karst
geology.
­
delay
in
planting
and
harvesting:
e.
g.,
the
plant­
back
interval
for
telone+
chloropicrin
is
two
weeks
longer
than
methyl
bromide+
chloropicrin,
and
in
Michigan
an
additional
delay
would
occur
because
soil
temperature
must
be
higher
to
fumigate
with
alternatives.
Delays
in
planting
and
harvesting
result
in
users
missing
key
market
windows,
and
adversely
affect
revenues
through
lower
prices.
­
unsuitable
topography:
e.
g.,
alternatives
that
must
be
applied
with
drip
irrigation
may
not
be
suitable
in
areas
with
rolling
or
sloped
topography
due
to
uneven
distribution
of
the
fumigant.

SUMMARIZE
WHY
KEY
ALTERNATIVES
ARE
NOT
FEASIBLE:

Research
results
confirm
that
methyl
bromide
alternatives
options
provide
inconsistent
control
of
nutsedge
weed
species.
Nutsedge
is
an
extremely
competitive
weed
in
tomato
and
can
cause
significant
yield
losses
in
the
Southeast.
Methyl
bromide
alternatives
also
provide
incomplete
control
of
soil
pathogens
in
Michigan.

In
addition,
there
is
a
regulatory
prohibition
on
the
use
of
1,3­
D
on
karst
topography
in
the
South­
Eastern
United
States.
In
Michigan,
1,3­
D
can
only
be
used
when
soil
temperature
are
higher
than
required
for
using
methyl
bromide,
and
this
results
in
a
planting/
harvesting/
marketing
delay.
In
California,
alternatives
that
must
be
applied
with
drip
irrigation
may
not
be
suitable
in
areas
with
rolling
or
sloped
topography
due
to
uneven
distribution
of
the
fumigant.

(

IF
ONLY
PART
OF
THE
CROP
AREA
IS
TREATED
WITH
METHYL
BROMIDE,
INDICATE
THE
REASON
WHY
METHYL
BROMIDE
IS
NOT
USED
IN
THE
OTHER
AREA,
AND
IDENTIFY
WHAT
ALTERNATIVE
STRATEGIES
ARE
USED
TO
CONTROL
THE
TARGET
PATHOGENS
AND
WEEDS
WITHOUT
METHYL
BROMIDE
THERE.

The
primary
reason
that
some
tomatoes
may
be
grown
without
methyl
bromide
in
all
three
regions
is
the
absence
of
key
target
pests
(
i.
e.,
nutsedge
in
the
Southeast,
soil
pathogens
in
Michigan,
and
pathogens
and
nematodes
in
California).

In
Florida,
areas
without
karst
geology
and
having
low
nutsedge
pressure
can
successfully
employ
a
fumigation
system
relying
on
1,3­
D
and
chloropicrin.

In
Michigan,
the
majority
of
tomato
producing
acres
do
not
have
Phytopthora
spp.,
and
do
not
use
methyl
bromide.

In
California,
areas
with
flat
terrain
successfully
employ
1,3­
D
with
chloropicrin
as
a
fumigant.

7.
(

WOULD
IT
BE
FEASIBLE
TO
EXPAND
THE
USE
OF
THESE
METHODS
TO
COVER
AT
LEAST
PART
OF
THE
CROP
THAT
HAS
REQUESTED
USE
OF
METHYL
BROMIDE?
WHAT
CHANGES
WOULD
BE
NECESSARY
TO
ENABLE
THIS?

No,
areas
that
use
methyl
bromide
do
so
because
hilly
terrain,
cold
soil
temperatures,
and
heavy
pest
pressure
preclude
the
use
of
fumigants
that
are
employed
when
these
conditions
are
not
present.

QUANTITY
NOMINATED
FOR
EACH
REGION:

The
amount
of
methyl
bromide
nominated
by
the
US
was
calculated
as
follows:

 
The
percent
of
regional
hectares
in
the
applicant's
request
was
divided
by
the
total
area
planted
in
that
crop
in
the
region
covered
by
the
request.
Values
greater
than
100
percent
are
due
to
the
inclusion
of
additional
varieties
in
the
applicant's
request
that
were
not
included
in
the
USDA
National
Agricultural
Statistics
Service
surveys
of
the
crop.
 
Hectares

of
an
application
to
a
crop
that
also
uses
methyl
bromide
were
subtracted.
There
was
no
double

INDICATE
IF
ANY
OF
THE
ABOVE
CHARACTERISTICS
IN

(
i)
PREVENT
THE
UPTAKE
OF
ANY
RELEVANT
ALTERNATIVES?

Telone
fumigation
controls
nematodes.
Chloropicrin
controls
fungal
pathogens.
A
combination
of
telone
and
chloropicrin
may
be
a
technically
feasible
alternative
for
methyl
bromide
on
flat
terrain.
However,
this
CUE
is
only
for
hilly,
rolling
terrain
where
these
alternatives
would
not
be
uniformly
distributed
by
the
irrigation
systems.

Metam
sodium
alone
or
metam
sodium
plus
chloropicrin
will
not
control
root
knot
nematodes.
In
addition,
rolling
field
topography
having
varied
soil
textures
does
not
allow
uniform
application
of
metam
sodium.
This
may
result
in
pockets
of
high
and
low
concentrations
of
metam
sodium.
High
concentrations
of
metam
sodium
can
be
phytotoxic
to
the
tomatoes,
limiting
its
usefulness
as
an
alternative
in
areas
of
hilly
or
rolling
terrain.
The
surviving
fungal
pathogen
populations
can
build
up
quickly
to
kill
tomato
plants

Soil
solarization
The

is
for
tomatoes
grown
in
the
coastal
areas
of
California,
which
have
mild
weather
conditions
(
15
­
25
C
temperatures).
The
weather
conditions
restrict
soil
solarization
as
alternative
to
methyl
bromide.
No
Steam
While
steam
has
been
used
effectively
against
fungal
pests
in
protected
production
systems,
such
as
greenhouses,
there
is
no
evidence
that
it
would
be
effective
in
open
tomato
fields.
Any
such
system
would
also
require
large
amounts
of
energy
and
water
to
provide
sufficient
steam
necessary
to
pasteurize
soil
down
to
the
rooting
depth
of
field
crops
(
at
least
20­
50
cm).
No
Biological
Control
Biological
control
agents
are
not
technically
feasible
alternatives
to

because
they
alone
cannot
control
the
soil

and/
or
nematodes.
While
biological

may
have
utility
as

strategy,
it

Crop
rotation
and

The
land

and
there
are
not

The
fungal

and
therefore
it
is
not
a

endophytes
that
will
control
fungal

pathogens.
No
Flooding/
Water

Flooding
is
not
technically
feasible
as
an
alternative
because
it
does
not
have
any
suppressive
effect
on
fungal
plant
pathogens
and
nematodes.
In
addition,
it
is
prohibitively
expensive
and
there
are

of

Grafting

are
thus
also

SUMMARY
OF
TECHNICAL
FEASIBILITY
The
US
EPA
has
determined
that
in
flat
terrain,
only
1,3­
D
+
chloropicrin
and
metam
sodium
+
chloropicrin
can
be
technically
feasible
against
the
key
pests
of
tomatoes
grown
in
California.
Metam­
sodium
alone
will
not
control
nematodes
and
may
be
phytotoxic
to
plants
because
of
undulating
land
topography
of
tomato
fields.
A
mixture
of
metam
sodium
and
chloropicrin
will
not
control
nematodes.
In
addition,
this
mixture
may
also
be
phytotoxic
due
to
undulating
land
topography.
A
mixture
of
1,3­
D
and
chloropicrin
is
unreliable
in
undulating
topography
because
of
uneven
distribution
of
the
fumigant
through
drip
irrigation
systems.
Currently
unregistered
alternatives,
such
as
methyl
iodide,
sodium
azide
or
propargyl
bromide
have
shown
good
efficacy
against
the
key
pests.
However,
even
if
registration
is
pursued
soon
the
commercial
tomato
growers
will
need
transition
period
for
adoption
in
California.

There
are
also
no
non­
chemical
alternatives
that
are
currently
viable
for
MB
replacement
for
commercial
tomato
growers.

The
applicant
submitted
the
results
of
one
small
scale
field
trial
on
the
efficacy
of
methyl
bromide
alternatives
in
controlling
the
pest
and
their
effect
on
tomato
yield
(
Hausbeck
and
Cortwright,
2003).
This
study
focused
on
tomato
and
a
number
of
vegetable
crops
(
cucurbits,
winter
squash,
and
melons).
As
of
July
2003,
results
showed
that
methyl

resulted
in

Untreated

suffered
7.1%

The
fields
were
treated
on
May
15
and

2003,
and
the
weather
was
unusually
cooler
than
normal
during
May

2003.
The
results
are
inconclusive.
This
study
may
be
repeated
during

The

claims
that
the

using

The

claims
that
these

are
expected
if
the
grower
fumigate
their
fields
in
early
May
instead
of
April
(
using

In

states
that

The

SUMMARY
OF
TECHNICAL
FEASIBILITY
Although
the
U.
S.
E.
P.
A.
determined
that
metam
sodium
and
a
combination
of
telone
+
chloropicrin
can
control
the
key
pest,
Phytophthora,
the
planting
and
harvesting
delay
due
to
cold
soil
temperatures
and
longer
plant­
back
interval
lead
to
a
shorter
growing
season
and
missing
key
market
windows
when
commodity
prices
are
most
favorable.
These
alternatives
have
plant
back
restriction
of
14­
28
days.
The
plant
back
restriction
delays
tomato
harvest
by
14­
28
days.
The
delayed
harvest
results
in
lower
net
revenues
per
acre
because
tomato
prices
decline
as
season
progresses.

Currently
unregistered
alternatives,
such
as
methyl
iodide,
sodium
azide,
propargyl
bromide
and
furfural
have
good
efficacy
against
the
key
pests
involved.
However,
even
if
registration
is
pursued,
the
growers
will
need
transition
time
to
adopt
them.

CHEMICAL
ALTERNATIVES
Telone
Effective
against
nematodes,
but
not
against
fungal
plant
pathogens
and
nutsedge
weeds.
Approximately
40%
of
tomato
land
has
Karst
geology.
Growers
with
Karst
topography
can
not
use
telone
because
of
underground
water
contamination.
No
Metam
sodium
It
will
control
many
weeds
but
control
of
nutsedge
is
very
inconsistent.
It
is
not
very
effective
against
nematode
population.
No
Chloropicrin
Chloropicrin
controls
soil
fungi
only.
It
also
stimulates
nutsedge
weed
growth
and
therefore
it
is
not
a
viable
option.
It
occasionally
stimulates
nutsedge
emergence
but
also
occasionally
controls
nutsedge
as
noted
in
the
literature.
Again
the
issue
is
its
inability
to
get
consistent
control
(
Culpepper,
2004).
No
NON
CHEMICAL
ALTERNATIVES
Soil
solarization
For
nutsedge
control
in
the
southeastern
U.
S.
states,
solarization
is
unlikely
to
be
technically
feasible
as
a
methyl
bromide
alternative.
Research
indicates
that
the
lethal
temperature
for
nutsedge
tubers
is
50oC
or
higher
(
Chase
et
al.
1999).
While
this
may
be
achieved
for
some
portion
of
the
autumn
cropping
in
southern
cucurbit
growing
regions,
it
is
very
unlikely
for
any
portion
of
the
spring
crops.
Trials
conducted
in
mid­
summer
in
Georgia
resulted
in
maximal
soil
temperatures
of
43oC
at
5
cm
depth,
not
high
enough
to
destroy
nutsedge
tubers,
and
tubers
lodged
deeper
in
the
soil
would
be
completely
unaffected.
No
Steam
Steam
is
not
a
technically
feasible
alternative
for
open
field
tomato
production
because
it
requires
sustained
heat
over
a
required
period
of
time
(
UNEP
1998).
While
steam
has
been
used
effectively
against
fungal
pests
in
protected
production
systems,
such
as
greenhouses,
there
is
no
evidence
that
it
would
be
effective
in
tomato
fields.
Any
such
system
would
also
require
large
amounts
of
energy
and
water
to
provide
sufficient
steam
necessary
to
pasteurize
soil
down
to
the
rooting
depth

Cover

appear
to

not

(
Burgos
and
Talbert
1996).
Mulching
has
also
been
shown
to
be
ineffective
in
controlling
nutsedges,
since
these

feasible
alternative
to

because
it

The

As

than
the

Furthermore,
nutsedge

can
produce

This
enhances
their

Flooding/
Water

Flooding
has
never
been
shown
to
control
nutsedge

Nutsedges
are
much
more
tolerant
of
watery
conditions
than
many
other
weed
pests.
For
example,
Horowitz
(
1972)
showed
that
submerging
nutsedge
in
flowing
or
stagnant
water
(
for
8
days
and
4
weeks,
respectively)
did
not
affect
the

There
are
also
serious
practical
obstacles
to
implementing
flood
management
approaches
in
cucurbit
production
in
the
southern

southeastern
U.
S.
states.
Droughts
are
common
in
many

Additional
notes
on
specific
herbicides
listed:
Halosulfuron­
methyl
In
December
2002,
halosulfuron­
methyl
(
Sandea
®
)
was
registered
for
weed
control
(
including
nutsedge)
in
tomatoes,
peppers,
eggplant,
and
cucurbits.
This
recent
registration
was
not
on
the
list
of
alternatives
from
Page
35
MBTOC
and
several
years
are
needed
to
see
if
it
will
be
adopted.
Historically,
in
the
United
States
it
has
taken
three
to
five
years
for
an
herbicide
to
be
adopted
by
a
significant
number
of
vegetable
crop
growers.

Halosulfuron­
methyl
has
a
number
of
limitations
which
may
affect
its
widespread
adoption,
that
include:
(
1)
phyto­
toxicity
with
moderate
rainfall
immediately
after
application;
(
2)
cool
temperatures,
(
3)
susceptible
varieties,
and
(
4)
plant
back
restrictions.
Specifically:
 
Rainfall
or
sprinkler
irrigation
greater
than
2.5
cm,
soon
after
a
pre­
emergent
application
of
halosulfuronmethyl
may
cause
crop
injury.
Sudden
storms
with
greater
than
2.5
cm
of
rainfall
are
common
in
Florida
and
other
areas
of
the
southeastern
United
States.
In
addition,
rainfall
within
four
hours
after
a
postemergence
application
of
halosulfuron­
methyl
may
reduce
effectiveness
and
cause
crop
injury.
 
Under
cool
temperatures
that
can
delay
early
seedling
emergence
or
growth,
halosulfuron
methyl
can
cause
injury
or
crop
failure.
This
is
especially
likely
to
occur
during
the
first
planting
of
the
season.
In
addition,
not
all
hybrids/
varieties
of
tomatoes
have
been
tested
for
sensitivity
to
halosulfuron­
methyl.
Halosulfuron
may
also
delay
maturity
of
treated
crops.
 
Halosulfuron
methyl
plant
back
restrictions
are
up
to
36
months.
Many
of
the
vegetable
crops
fall
within
the
4
to
12
month
range,
although
some
are
longer.
There
are
label
limitations
for
halosulfuron
methyl.
As
per
product
label,
halosulfuron
methyl
should
not
be
applied
if
the
crop
or
target
weeds
are
under
stress
due
to
drought,
water
saturated
soils,
low
fertility,
or
other
poor
growing
conditions.
This
herbicide
can
not
be
applied
to
soil
that
has
been
treated
with
organophosphate
insecticides.
Foliar
applications
of
organophosphate
insecticides
may
not
be
made
within
21
days
before
or
7
days
after
halosulfuron
methyl
application.
Note:
All
the
limitations
above
are
listed
in
the
US
registration
label
for
halosulfuron,
which
in
turn
is
based
on
proprietary
data
submitted
to
EPA
by
the
registrant
company.

S­
metolachlor
It
was
registered
for
use
in
tomatoes
in
April
2003.
However,
it
is
not
registered
in
states
of
concern,
and
does
not
control
purple
nutsedge
or
nightshade
species.
Further,
it
does
not
provide
commercially
acceptable
weed
control
in
plasticulture
systems.
Rimsulfuron
There
is
evidence
that
rimsulfuron
only
provides
suppressive
control
of
yellow
nutsedge
(
40
to
70
percent
control)
(
Nelson
et
al,
2002).
In
addition,
the
label
warns
against
tank
mixing
with
organophosphate
insecticides
because
injury
to
the
crop
may
occur.
Also,
for
most
of
the
vegetable
crops
besides
tomatoes
there
is
a
12­
month
plant
back
restriction.
This
plant
back
restriction
can
seriously
compromise
the
needed
rotational
interval
needed
for
IPM
programs.

SUMMARY
OF
TECHNICAL
FEASIBILITY
The
submitted
data
showed
that
using
the
above
best
alternative
the
growers
are
expected
to
suffer
6.2%
yield
losses
(
Chellemi,
Botts
and
Noling.
2001).
A
combination
of
1,3­
D
+
chloropicrin
+
pebulate
appeared
to
be
the
best
alternative
in
controlling
key
pests
in
tomato
fields.
Since
pebulate
is
no
longer
available
then
the
growers
will
need
to
substitute
another
herbicides
such
as
halosulfuron,
rimsulfuron
or
trifloxysulfuron
to
control
nutsedge
weeds.
But,
these
herbicides
have
significant
limitations,
as
described
in
the
notes
to
Table
15.1.
In
addition,
losses
will
be
higher
in
areas
of
Karst

TECHNIQUES

OR
ARE

PLANNED
FOR
THE
CIRCUMSTANCES
OF
THE
NOMINATION,
STATE
REASONS:

In
accordance
with
the
criteria
of
the
critical
use
exemption,
each
party
is
required
to
describe
ways
in
which
it
strives
to
minimize
use
and
emissions
of
methyl
bromide.
The
use
of
methyl
bromide
in
the
growing
of
cucurbit
nurseries
in
the
United
States
is
minimized
in
several
ways.
First,
because
of
its
toxicity,
methyl
bromide
has,
for
the
last
40
years,
been
regulated
as
a
restricted
use
pesticide
in
the
United
States.
As
a
consequence,
methyl
bromide
can
only
be
used
by
certified
applicators
who
are
trained
at
handling
these
hazardous
pesticides.
In
practice,
this
means
that
methyl
bromide
is
applied
by
a
limited
number
of
very
experienced
applicators
with
the
knowledge
and
expertise
to
minimize
dosage
to
the
lowest
level
possible
to
achieve
the
needed
results.
In
keeping
with
both
local
requirements
to
avoid
"
drift"
of
methyl
bromide
into
inhabited
areas,
as
well
as
to
preserve
methyl
bromide
and
keep
related
emissions
to
the
lowest
level
possible,
methyl
bromide
application
for
cucurbits
is
most
often
machine
injected
into
soil
to
specific
depths.

As
methyl
bromide
has
become
more
scarce,
users
in
the
United
States
have,
where
possible,
experimented
with
different
mixes
of
methyl
bromide
and
chloropicrin.
Specifically,
in
the
early
1990s,
methyl
bromide
was
typically
sold
and
used
in
methyl
bromide
mixtures
made
up
of
95%
Page
40
methyl
bromide
and
5%
chloropicrin,
with
the
chloropicrin
being
included
solely
to
give
the
chemical
a
smell
enabling
those
in
the
area
to
be
alerted
if
there
was
a
risk.
However,
with
the
outset
of
very
significant
controls
on
methyl
bromide,
users
have
been
experimenting
with
significant
increases
in
the
level
of
chloropicrin
and
reductions
in
the
level
of
methyl
bromide.
While
these
new
mixtures
have
generally
been
effective
at
controlling
target
pests,
at
low
to
moderate
levels
of
infestation,
it
must
be
stressed
that
the
long
term
efficacy
of
these
mixtures
is
unknown.

Tarpaulin
(
high
density
polyethylene)
is
also
used
to
minimize
use
and
emissions
of
methyl
bromide.
In
addition,
cultural
practices
are
utilized
by
cucurbit
growers.

Reduced
methyl
bromide
concentrations
in
mixtures,
cultural
practices,
and
the
extensive
use
of
tarpaulins
to
cover
land
treated
with
methyl
bromide
has
resulted
in
reduced
emissions
and
an
application
rate
that
we
believe
is
among
the
lowest
in
the
world
for
the
uses
described
in
this
nomination.

PART
E:
ECONOMIC
ASSESSMENT
The
following
economic
analysis
is
organized
by
MeBr
critical
use
application.
Cost
of
MeBr
and
alternatives
are
given
first
in
table
21.1.
This
is
followed
in
table
22.1
by
a
listing
of
net
and
gross
revenues
by
applicant.
Expected
losses
when
using
MeBr
alternatives
are
then
decomposed
in
tables
E1
through
E3.

Reader
please
note
that
in
this
study
net
revenue
is
calculated
as
gross
revenue
minus
operating
costs.
This
is
a
good
measure
as
to
the
direct
losses
of
income
that
may
be
suffered
by
the
users.
It
should
be
noted
that
net
revenue
does
not
represent
net
income
to
the
users.
Net
income,
which
indicates
profitability
of
an
operation
of
an
enterprise,
is
gross
revenue
minus
the
sum
of
operating
and
fixed
costs.
Net
income
should
be
smaller
than
the
net
revenue
measured
in
this
study.
We
did
not
include
fixed
costs
because
it
is
often
difficult
to
measure
and
verify.

SUMMARY
OF
ECONOMIC
FEASIBILITY
The
economic
analysis
of
the
tomato
application
compared
data
on
yields,
crop
prices,
revenues
and
costs
using
methyl
bromide
and
using
alternative
pest
control
regimens
in
order
to
estimate
the
loss
of
methyl
bromide
availability.
The
alternatives
identified
as
technically
feasible
­
in
cases
of
low
pest
infestation
­
by
the
U.
S.
are:
(
a)
1,3­
Dichloropropene
+
Chloropicrin;
(
b)
Metam
sodium;
and
(
c)
Chloropicrin.
Changes
in
pest
control
costs
for
tomatoes
are
less
than
4
percent
of
total
variable
costs
therefore
they
would
have
little
impact
on
any
of
the
economic
measures
used
in
the
analysis.

The
economic
factors
that
really
drives
the
feasibility
analysis
for
fresh
market
tomato
uses
of
methyl
bromide
are:
(
1)
yield
losses,
referring
to
reductions
in
the
quantity
produced,
(
2)
increased
production
costs,
which
may
be
due
to
the
higher­
cost
of
using
an
alternative,
additional
pest
control
requirements,
and/
or
resulting
shifts
in
other
production
or
harvesting
practices
(
3)
quality
losses,
which
generally
affect
the
quantity
and
price
received
for
the
goods,
and
(
4)
missed
market
windows
due
to
plant
back
time
restrictions,
which
also
affect
the
quantity
and
price
received
for
the
goods.

The
economic
reviewers
then
analyzed
crop
budgets
for
pre­
plant
sectors
to
determine
the
likely
economic
impact
if
methyl
bromide
were
unavailable.
Various
measures
were
used
to
quantify
the
impacts,
including
the
following:

(
1)
Loss
per
Hectare.
For
crops,
this
measure
is
closely
tied
to
income.
It
is
relatively
easy
to
measure,
but
may
be
difficult
to
interpret
in
isolation.
Page
44
(
2)
Loss
per
Kilogram
of
Methyl
Bromide.
This
measure
indicates
the
value
of
methyl
bromide
to
crop
production.

(
3)
Loss
as
a
Percentage
of
Gross
Revenue.
This
measure
has
the
advantage
that
gross
revenues
are
usually
easy
to
measure,
at
least
over
some
unit,
e.
g.,
a
hectare
of
land
or
a
storage
operation.
However,
high
value
commodities
or
crops
may
provide
high
revenues
but
may
also
entail
high
costs.
Losses
of
even
a
small
percentage
of
gross
revenues
could
have
important
impacts
on
the
profitability
of
the
activity.

(
4)
Loss
as
a
Percentage
of
Net
Operating
Revenue.
We
define
net
cash
revenues
as
gross
revenues
minus
operating
costs.
This
is
a
very
good
indicator
as
to
the
direct
losses
of
income
that
may
be
suffered
by
the
owners
or
operators
of
an
enterprise.
However,
operating
costs
can
often
be
difficult
to
measure
and
verify.

(
5)
Operating
Profit
Margin.
We
define
operating
profit
margin
to
be
net
operating
revenue
divided
by
gross
revenue
per
hectare.
This
measure
would
provide
the
best
indication
of
the
total
impact
of
the
loss
of
methyl
bromide
to
an
enterprise.
Again,
operating
costs
may
be
difficult
to
measure
and
fixed
costs
even
more
difficult,
therefore
fixed
costs
were
not
included
in
the
analysis.

These
measures
represent
different
ways
to
assess
the
economic
feasibility
of
methyl
bromide
alternatives
for
methyl
bromide
users,
who
are
tomato
producers
in
this
case.
Because
producers
(
suppliers)
represent
an
integral
part
of
any
definition
of
a
market,
we
interpret
the
threshold
of
significant
market
disruption
to
be
met
if
there
is
a
significant
impact
on
commodity
suppliers
using
methyl
bromide.
The
economic
measures
provide
the
basis
for
making
that
determination.

California
We
conclude
that,
at
present,
no
economically
feasible
alternatives
to
MeBr
exist
for
use
in
California
tomato
production.
Yield
loss
in
California
tomato
production
is
expected
to
be
15~
20%
when
using
MeBr
alternatives.
Growers
will
experience
loss
on
a
per
hectare
basis
of
approximately
US$
8,618
to
US$
11,059
and
approximately
10%
and
35%
losses
in
gross
and
net
operating
revenues,
respectively.
These
measures
clearly
indicate
that
Metam­
Sodium
is
not
an
economically
feasible
alternative
to
MeBr.

We
have
quantified
the
economic
conditions
of
tomato
growers
as
best
as
possible
but,
primarily
due
to
limited
data
availability,
are
unable
to
capture
every
aspect
of
the
economic
picture
in
our
numeric
analysis.
Factors
not
accounted
for
in
this
analysis
are
distribution
of
yield
loss
across
individual
growers
and
the
yield
risk
associated
with
using
MeBr
alternatives.

Michigan
We
conclude
that,
at
present,
no
economically
feasible
alternatives
to
MeBr
exist
for
use
in
Michigan
tomato
production.
Three
factors
have
proven
most
important
in
our
conclusion.
These
are
yield
loss,
quality
loss,
and
missed
market
windows,
which
are
discussed
individually
below.

Expected

Missed
Market
Windows
­
We
agree
with
Michigan's
assertion
that
growers
will
likely
receive
significantly
lower
prices
for
their
produce
if
they
switch
to
1,3­
D
+
chloropicrin
or
Metam­
Sodium
or
Chloropicrin.
This
is
due
to
changes
in
the
harvest
schedule
caused
by
the
above
described
soil
temperature
complications
and
extended
plant
back
intervals
when
using
these
alternatives.

Our
analysis
of
this
effect
is
based
on
the
fact
that
prices
farmers
receive
for
their
tomatoes
vary
widely
over
the
course
of
the
growing
season.
Driving
these
fluctuations
are
the
forces
of
supply
and
demand.
Early
in
the
growing
season,
when
relatively
few
tomatoes
are
harvested,
the
supply
is
at
is
lowest
and
the
market
price
is
at
its
highest.
As
harvested
quantities
increase,
the
price
declines.
In
order
to
maximize
their
revenues,
tomato
growers
manage
their
production
systems
with
the
goal
of
harvesting
the
largest
possible
quantity
of
tomatoes
when
the
prices
are
at
their
highs.
The
ability
to
sell
produce
at
these
higher
prices
makes
a
significant
contribution
toward
the
profitability
of
tomato
operations.

To
describe
these
conditions
in
Michigan
tomato
production,
we
used
daily
tomato
sales
data
from
the
U.
S.
Department
of
Agriculture
for
the
previous
year
to
gauge
the
impact
of
early
season
price
fluctuations
on
gross
revenues.
Though
data
availability
is
limiting,
we
assume
that
if
tomato
growers
adjust
the
timing
of
their
production
system,
as
required
when
using
1,3­
D
+
Chloropicrin
or
Metam­
Sodium
or
Chloropicrin,
that
they
will,
over
the
course
of
the
growing
season,
accumulate
gross
revenues
reduced
by
approximately
4~
11%.
We
reduced
the
season
average
price
by
4~
11%
in
our
analysis
of
the
alternatives
to
reflect
this.
Based
on
currently
available
information,
we
believe
this
reduction
in
gross
revenues
serves
as
a
reasonable
indicator
of
the
typical
effect
of
planting
delays
resulting
when
MeBr
alternatives
are
used
in
Michigan.

Southeastern

We
conclude
that,
at
present,
no
economically
feasible
alternatives
to
MeBr
exist
for
use
in
Southeastern

tomato
production.
Two
factors
have

WHAT
ACTIONS
WILL
BE
TAKEN
TO
RAPIDLY
DEVELOP
AND
DEPLOY
ALTERNATIVES
FOR
THIS
CROP?
(
Based
on
responses
to
Question
13,
the
answer
should
include
activities
that
would
be
undertaken
to
overcome
the
difficulties
that
resulted
in
the
alternatives
being
considered
unsuitable.
Include
a
timetable
for
completion
of
key
activities.):

Since
1997,
the
United
States
EPA
has
made
the
registration
of
alternatives
to
methyl
bromide
a
high
registration
priority.
Because
the
EPA
currently
has
more
applications
pending
in
its
registration
review
queue
than
the
resources
to
evaluate
them,
EPA
prioritizes
the
applications.
By
virtue
of
being
a
top
registration
priority,
methyl
bromide
alternatives
enter
the
science
review
process
as
soon
as
U.
S.
EPA
receives
the
application
and
supporting
data
rather
than
waiting
in
turn
for
the
EPA
to
initiate
its
review.

As
one
incentive
for
the
pesticide
industry
to
develop
alternatives
to
methyl
bromide,
the
Agency
has
worked
to
reduce
the
burdens
on
data
generation,
to
the
extent
feasible
while
still
ensuring
that
the
Agency's
registration
decisions
meet
the
Federal
statutory
safety
standards.
Where
appropriate
from
a
scientific
standpoint,
the
Agency
has
refined
the
data
requirements
for
a
given
pesticide
application,
allowing
a
shortening
of
the
research
and
development
process
for
the
methyl
bromide
alternative.
Furthermore,
Agency
scientists
routinely
meet
with
prospective
methyl
bromide
alternative
applicants,
counseling
them
through
the
preregistration
process
to
increase
the
probability
that
the
data
is
done
right
the
first
time
and
rework
delays
are
minimized
The
U.
S.
EPA
has
also
co­
chaired
the
U.
S.
DA/
EPA
Methyl
Bromide
Alternatives
Work
Group
since
1993
to
help
coordinate
research,
development
and
the
registration
of
viable
alternatives.
This
coordination
has
resulted
in
key
registration
issues
(
such
as
worker
and
bystander
exposure
through
volatilization,
township
caps
and
drinking
water
concerns)
being
directly
addressed
through
USDA's
Agricultural
Research
Service's
U.
S.$
15
million
per
year
research
program
conducted
at
more
than
20
field
evaluation
facilities
across
the
country.
Also
EPA's
participation
in
the
evaluation
of
research
grant
proposals
each
year
for
USDA's
U.
S.$
2.5
million
per
year
methyl
bromide
alternatives
research
has
further
ensured
close
coordination
between
the
U.
S.
government
and
the
research
community.

As
per
Culpepper
(
2004),
over
50
vegetable
trials,
focusing
on
weed
management,
were
conducted
by
the
University
of
Georgia.
Four
of
these
trials
compared
methyl
bromide
alternatives
and
another
30
trials
searched
for
the
development
and
labeling
of
new
herbicides
for
vegetables.
During
2004,
these
experiments
will
be
continued
to
find
methyl
bromide
alternatives.

The
amount
of
methyl
bromide
requested
for
research
purposes
is
considered
critical
for
the
development
of
effective
alternatives.
Without
methyl
bromide
for
use
as
a
standard
treatment,
the
research
studies
can
never
address
the
comparative
performance
of
alternatives.
This
would
be
a
serious
impediment
to
the
development
of
alternative
strategies.
The
U.
S.
government
estimates
that
tomatoes
research
will
require
5501
kg
per
year
of
methyl
bromide
for
2005
and
2006.
This
research
request
also
includes
the
amounts
for
asparagus,
cabbage,
ginseng,
and
Page
48
nutsedge
for
74
kg
per
year.
This
amount
of
methyl
bromide
is
necessary
to
conduct
research
on
alternatives
and
is
in
addition
to
the
amounts
requested
in
the
submitted
CUE
applications.
One
example
of
the
research
is
a
field
study
testing
the
comparative
performance
of
methyl
bromide,
host
resistance,
cultural
practices,
pest
management
approaches
for
control
of
root­
knot
nematodes.
Another
example
is
a
five
year
field
study
comparing
methyl
bromide
to
1,3­
D
combined
with
biologically
based
materials
including
transplant
treatments
for
control
of
weeds,
root­
knot
nematodes
and
soil
borne
fungal
pathogens.

HOW
DO
YOU
PLAN
TO
MINIMIZE
THE
USE
OF
METHYL
BROMIDE
FOR
THE
CRITICAL
USE
IN
THE
FUTURE?
(
Include
a
plan
of
the
stepwise
reduction
schedule
for
methyl
bromide
as
alternatives
are
phased
in
and/
or
additional
emission
controls
are
implemented):

The
U.
S.
wants
to
note
that
our
usage
rate
is
among
the
lowest
in
the
world
in
requested
sectors
and
represents
efforts
of
both
the
government
and
the
user
community
over
many
years
to
reduce
use
rates
and
emissions.
We
will
continue
to
work
with
the
user
community
in
each
sector
to
identify
further
opportunities
to
reduce
methyl
bromide
use
and
emissions.
Georgia
experts
(
Culpepper,
2004)
note
that
the
ability
to
reduce
the
use
of
methyl
bromide
will
rely
on
the
interaction
of
fumigant
alternatives,
plastic
mulches
and
herbicide
systems
under
specific
growing
conditions.
More
time
is
needed
to
develop
these
systems.

ADDITIONAL
COMMENTS
ON
THE
NOMINATION?)

Research
efforts
began
in
the
early
1990'
s
to
find
out
methyl
bromide
alternatives
in
various
crops
including
tomato.
With
each
year
of
experimentation
the
researchers
became
more
familiar
and
efficient
with
methyl
bromide
fumigant
alternatives
for
nutsedge
management.
The
researchers
learned
strengths
and
weakness
of
each
fumigant
system,
plastic
film
types,
herbicide
system,
and
various
production
environments.
The
researchers
need
more
time
to
evaluate
and
refine
these
systems
in
large
scale
trials
prior
to
large
scale
implementation
at
growers
field
level.

requested
by
factoring
in
the
specific
situations

We
have
tried
to
make
the

in
the
most
appropriate
category
when
the

Percent
karst
topography
is
the
proportion
of
the

that
is
characterized
by
karst
formations.
In
these
areas,
the
groundwater
can
easily
become
contaminated
by
pesticides
or
their
residues.
Regulations
are
often
in
place
to
control
the
use
of
pesticide
of
concern.
Dade
County,
Florida,
has
a

For
example,
the
key
pest
in
Michigan
peppers,
Phytophthora

pursuant
to
state
and
local
limits
on
their

(%)
 
Unsuitable
terrain
(%)
is
the
percent

where
alternatives
cannot
be
used
due
to
soil
type
(
e.
g.,
heavy
clay
soils
may
not
show
adequate
performance)
or
terrain
configuration,
such
as
hilly
terrain.
Where
the
use
of

problems.
21.
Cold

Temperatures
 
Cold
soil
temperatures
is
the
proportion
of
the
requested
acreage
where
soil
temperatures
remain
too
low
to
enable
the
use
of
methyl
bromide
alternatives
and
still
have
sufficient
time
to
produce
the
normal
(
one
or
two)
number
of

or
to
allow

sufficiently
early
to

at
the
beginning
of
the

22.
Combined

(%)
­
Total
combined
impacts
are
the
percent
(%)
of
the
requested
area
where
alternatives
cannot
be
used
due
to
key
pest,
regulatory,
soil
impacts,
temperature,
etc.
In
each
case
the
total
area
impacted
is
the
conjoined
area
that
is
impacted
by
any
individual
impact.
The
effects
were
assumed
to
be
independently
distributed
unless
contrary
evidence
was
available
(
e.
g.,
affects
are
known
to
be
mutually
exclusive).
For
example,
if
50%
of
the
requested
area
had
moderate
to
severe
key
pest
pressure
and
50%
of
the
requested
area
had
karst
topography,
then
75%
of
the
area
was
assumed
to
require
methyl
bromide
rather
than
the
alternative.
This
was
calculated
as
follows:
50%
affected
by
key
pests
and
an
additional
25%
(
50%
of
50%)
affected
by
karst

SUMMARY
OF
NEW
APPLICANTS
A
number
of
new
groups
applied
for
methyl
bromide
for
2005
during
this
application
cycle,
as
shown
in
the
table
below.
Although
in
most
cases
they
represent
additional
amounts
for
sectors
that
were
already
well­
characterized
sectors,
in
a
few
cases
they
comprised
new
sectors.
Examples
of
the
former
include
significant
additional
country
(
cured,
uncooked)
ham
production;
some
additional
request
for
tobacco
transplant
trays,
and
very
minor
amounts
for
pepper
and
eggplant
production
in
lieu
of
tomato
production
in
Michigan.

For
the
latter,
there
are
two
large
requests:
cut
flower
and
foliage
production
in
Florida
and
California
(`
Ornamentals')
and
a
group
of
structures
and
process
foods
that
we
have
termed
`
Post­
Harvest
NPMA'
which
includes
processed
(
generally
wheat­
based
foods),
spices
and
herbs,
cocoa,
dried
milk,
cheeses
and
small
amounts
of
other
commodities.
There
was
also
a
small
amount
requested
for
field­
grown
tobacco.

The
details
of
the
case
that
there
are
no
alternatives
which
are
both
technically
and
economically
feasible
are
presented
in
the
appropriate
sector
chapters,
as
are
the
requested
amounts,
suitably
adjusted
to
ensure
that
no
double­
counting,
growth,
etc.
were
included
and
that
the
amount
was
only
sufficient
to
cover
situations
(
key
pests,
regulatory
requirements,
etc.)
where
alternatives
could
not
be
used.

The
amount
requested
by
new
applicants
is
approximately
2.5%
of
the
1991
U.
S.
baseline,
or
about
1,400,000
pounds
of
methyl
bromide,
divided
40%
for
pre­
plant
uses
and
60%
for
postharvest
needs.

The
methodology
for
deriving
the
nominated
amount
used
estimates
that
would
result
in
the
lowest
amount
of
methyl
bromide
requested
from
the
range
produced
by
the
analysis
to
ensure
that
adequate
amounts
of
methyl
bromide
were
available
for
critical
needs.
We
are
requesting
additional
methyl
bromide
in
the
amount
of
about
500,000
Kg,
or
2%
or
the
1991
U.
S.
baseline,
to
provide
for
the
additional
critical
needs
in
the
pre­
plant
and
post­
harvest
sector.
