A. PAN's Explanation of Terms |
| Gross
pounds
of active ingredient: This number includes the total pounds
of the pesticide active ingredient applied to the selected crop
or site in the selected geographic area. Inert ingredients are
not included in this total. For some agricultural applications,
the gross pounds may be more than the pounds applied to acreage
because pesticides are used in processing the crop after harvest
or are used only on selected sites in the field (planting holes,
etc.). |
| Application
rate: This
number includes the total pounds of the pesticide active ingredient
applied to the selected crop or site in the selected geographic
area. Inert ingredients are not included in this total. |
'Acres Planted'
Acres Planted is the planted acreage of the crop in the selected
region where the selected chemical was applied. This figure
may not be the total acreage of the selected crop. To obtain
the total planted acreage for a crop or county, see the crop
and county pages available from the Pesticide Use Search Page.
See documentation for important distinctions between acres
treated and acres planted. |
| Acres
Treated
is the acreage of the crop actually treated with the pesticide.
Gross Pounds applied divided by Acres Treated is the application
rate of the pesticide. The difference between Acres Planted
and Acres Treated is best explained through an example:If a
farmer has a 100-acre field and sprays 50 acres, then the Acres
Planted will be 100 and the Acres Treated will be 50. If a farmer
sprays 50 of their 100 acres three times, then the Acres Planted
will remain at 100 acres, but now the value of Acres Treated
will be 150. This figure may not be the total acreage of the
selected crop. See documentation for further distinctions between
acres treated and acres planted. |
| Application
count indicates
the number of times this chemical was applied. |

There are two kinds of grapes reported
in the PUR data (wine and table). Due to errors and inconsistencies
in reporting the type of grapes, PUR acreage data is not

The maps are based on state-level estimates of pesticide use rates
for individual crops, which have been compiled by the National
Center for Food and Agricultural Policy (NCFAP) for 1991-1993
and 1995, and on county-based crop acreage data obtained from
the 1992 Census of Agriculture. For more information see http://ca.water.usgs.gov/pnsp/use92/
