Screening-level Usage Analysis (SLUA)

Date: December 5, 2006

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 1999 to
2005.

Private Pesticide Market Research – pesticide usage data from 1999 to
2005.

NCFAP 97 (National Center for Food and Agricultural Policy), and NPUD
2002 (National Pesticide Use Database) – insecticide usage data from
NCFAP 97, and fungicide and herbicide usage data from NPUD 02, of the
CropLife Foundation,  are used only if data are not available from the
other sources.

California DPR data can be requested separately.

What are the data limitations?

Additional registered uses may exist but are not included because either
the available surveys do not report usage (e.g., small acreage crops) or
these uses are not covered in the available surveys.

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?

All numbers rounded.		

'<500' indicates less than 500 pounds of active ingredient.		

'<2.5' indicates less than 2.5 percent of crop is treated.		

'<1'	indicates less than 1	percent of crop is treated.
