This report is a chemical use survey issued by the National Agricultural Statistics Service on livestock and reports on insecticide use information on dairy cattle and dairy facilities in 17 selected states. Active ingredients classified by the Environmental Protection Agency as pesticides are included in the report. Pharmaceutical products for internal pests are excluded, but dual purpose products that can be applied internally or externally are included. Chemical use data is provided on a rate per head per application and rate per head per year basis. However, there is significant variation based on product formulation, method of application, and pest condition. Insecticide use information on dairy facilities (applied for the control of insects and pests only) is also included in the report.
