Abstract
Pesticides (herbicides and insecticides) are used extensively in the White River Basin. Application of herbicides to corn and soybeans accounts for most of the use. The pesticides most frequently detected near the mouth of the White River during 1991-95 were the herbicides alachlor, atrazine, cyanazine, and metolachlor. The highest concentrations of herbicides in the river were typically found during late spring runoff following application. Generally, concentrations of alachlor have been decreasing while concentrations of acetochlor have been increasing in response to changes in the use of these herbicides in the basin. The total amount of the commonly used herbicides transported by the river is about 1 percent or less of the amount applied to cropland. Insecticides commonly used in urban and agricultural areas also were found but in much lower concentrations than commonly used herbicides.
