Screening Level Usage Analysis (SLUA)

Date: August 8, 2008 

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.

Pesticide usage data obtained from various sources.  The data are then
merged, averaged, and rounded so that the presented information is not
proprietary, business confidential, or trade secret. 

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 from U.S. states that produce 80%
or more of a crop, in most cases, or less than 80%, in rare cases,
depending on the scope of the survey and available resources.

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 across all
observations, 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 2001 to
2006.

Private pesticide market research – pesticide usage data from 2001 to
2006.

NPUD 2002 (National Pesticide Use Database) pesticide usage data from
NPUD 02 of the CropLife Foundation are used only if data are not
available from the other sources.

California Department of Pesticide Regulation (DPR) Pesticide Use
Reporting (PUR) data for 2000 to 2005 when 95% or more of a crop is
grown California.

What are the limitations to the data?

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 various factors, including, but not limited to
Section 18 requests, existing stocks of the chemical, data collection
errors, and experimental use permits (EUPs).
