What
is
a
Screening
Level
Usage
Analysis
(
SLUA)?

 
Available
estimates
of
pesticide
usage
data
for
a
particular
active
ingredient
that
is
used
on
agricultural
crops
in
the
United
States.
What
does
it
contain?

 
Pesticide
usage
data
for
a
single
active
ingredient
only.
 
Agricultural
use
sites
(
crops)
that
the
pesticide
is
reported
to
be
used
on.
 
Available
pesticide
usage
information
(
i.
e.,
does
not
include
all
of
the
United
States).
 
Annual
percent
of
crop
treated
(
average
&
maximum)
for
each
agricultural
crop.
 
Average
annual
pounds
of
the
pesticide
applied
for
each
agricultural
crop
(
i.
e.,
for
the
states
surveyed,
not
for
the
entire
United
States).
What
assumptions
can
I
make
about
the
reported
data?

 
Average
pounds
of
active
ingredient
applied
­
Values
are
calculated
by
merging
pesticide
usage
data
sources
together;
averaging
by
year,
averaging
across
all
years,
&
then
rounding.
Note:
If
the
estimated
value
is
less
than
500,
then
that
value
is
labeled
<
500.
Estimated
values
between
500
&
<
1,000,000
are
rounded
to
1
significant
digit.
Estimated
values
of
1,000,000
or
greater
are
rounded
to
2
significant
digits.)

 
Average
percent
of
crop
treated
­
Values
are
calculated
by
merging
data
sources
together;
averaging
by
year,
averaging
across
all
years,
&
rounding
to
the
nearest
multiple
of
5.
Note:
If
the
estimated
value
is
less
than
1,
then
the
value
is
labeled
<
1.

 
Maximum
percent
of
crop
treated
­
Value
is
the
single
maximum
value
reported
across
all
data
sources,
across
all
years,
&
rounded
up
to
the
nearest
multiple
of
5.
Note:
If
the
estimated
value
is
less
than
2.5,
then
the
value
is
labeled
<
2.5.
What
are
the
data
sources
used?

 
USDA­
NASS
(
United
States
Department
of
Agriculture's
National
Agricultural
Statistics
Service)
 
pesticide
usage
data
from
1998
to
2004.
 
NCFAP
(
National
Center
for
Food
and
Agricultural
Policy)
 
pesticide
usage
data
from
1997
and
used
only
if
data
are
not
available
from
the
other
sources.
 
Private
Pesticide
Market
Research
 
pesticide
usage
data
from
1998
to
2004.
 
California
DPR
data
can
be
requested
separately.

What
are
the
data
limitations?

 
Additional
registered
uses
may
exist
but
are
not
included
because
the
available
surveys
do
not
report
usage
(
e.
g.,
small
acreage
crops).
 
Lack
of
reported
usage
data
for
the
pesticide
on
a
crop
does
not
imply
zero
usage.
 
Usage
data
on
a
particular
site
may
be
noted
in
data
sources,
but
not
quantified.
In
these
instances,
the
site
would
not
be
reported
in
the
SLUA.
 
Non­
agricultural
use
sites
(
e.
g.,
turf,
post­
harvest,
mosquito
control,
etc.)
are
not
reported
in
the
SLUA.
A
separate
request
must
be
made
to
receive
these
estimates.
 
Some
sites
show
some
use,
even
though
they
are
not
on
the
label.
This
usage
could
be
due
to
Section
18
requests,
existing
stocks
of
the
chemical,
data
collection
errors,
experimental
use
permit
(
EUP),
and/
or
because
of
an
illegal
use.
Who
do
I
contact
for
further
information
and/
or
questions
on
this
SLUA?
