Screening Level Usage Analysis (SLUA)

Date: June 0 2 , 201 4

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 presen ted 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 u sage 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 cro p.

 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

ro unded 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, & roundin g to the nearest multiple of 5. Note: If the

estimated value is less than 2.5, then the value is labeled <2.5. 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 200 4 to 20 1 2

.

 Private pesticide market research

– pesticide usage data from 200 4 to 20 1 2

.

 California Department of Pesticide Regulation (DPR) Pe sticide Use Reporting (PUR) data for

200 4 to 20 1 1

. 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 fo r 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, mo squito 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 Sec tion 18 requests, existing stocks of the chemical,

data collection errors, and experimental use permits (EUPs).Date: June 0 2 , 2014

(Includes PC Codes: 56001, 56002, 56003, 56004, 56007, 56008 )

Sorted Alphabetically

Reporting Years: 200 4

- 201 2

Average Percent Crop T reated

Crop Lbs. A.I. Av era g e Max imum

1 Apples 5000 35 50

2 Avocados < 500 < 2.5 < 2.5

3 Olives < 500 5 5

4 Pears 2000 50 70

All numbers are rounded.

<500: less than 500 pounds of active ingredient.

<2.5: less than 2.5 percent of crop is treated.

SLUA data sources include:
