Interpretive Summary:

Technical Abstract: Scientists today acknowledge the important role played by agrochemicals in maintaining agricultural production, get issues remain concerning the movement of these crop protection chemicals away from their points of application and into nontarget natural resources. A wide variety of chemicals are used to address different pest control needs. The choices made by the producer often are determined by the nature of the landscape, pest cycles, cropping systems, weather patterns, and the economics of production. Hence, they differ across the U.S. We present an overview of incidental movement studies of pesticides used in production agriculture and their potential nontarget impacts within three distinct geophysical regions of the United States. Examples from laboratory, test plot, and field investigations of agrochemical movement will illustrate the importance of scale in the study design in the Chesapeake Bay Watershed, on the Midwestern Plains, and in California's San Joaquin Valley.
