资源简介：
The "National Herbicide Use Database," compiled by Resources for
the Future (RFF), contains data on herbicide use in agricultural
crop production throughout the United States. Estimates of use
for 96 active ingredients on 84 crops in the 48 contiguous
states of the United States are included in the database. Data
available for each crop include 1987 estimates for the number of
acres of harvested crop, the average rate of use per acre, the
total number of acres treated, and the total pounds of active
ingredient used. This information can be aggregated on a county,
regional (group of counties), state, or national level. Data are
used by regulatory officials, researchers, environmental groups,
and planning agencies to design policies for herbicide
monitoring in the environment and to evaluate proposed
regulatory actions.
