Excerpts from the report Summary: Information in this study is based on a survey of farmers whose sales represented 90 percent of total agricultural sales in the United States. Nearly all used some pesticides in 1964. Of the farmers surveyed, 94 percent used pesticides, either for treating crop and other land, livestock, and poultry, or for controlling rodents. These farmers spent $456 million on pesticides in 1964. In addition, supplementary information indicates that farmers who operated small farms but were not included in the survey spent about $58 million on pesticides. Thus, expenditures for pesticides by all farmers in 1964 amounted to $514 million. Of the total pesticide expenditures, 85 percent were for treating crops, about 11 percent were for treating livestock and poultry, and 4 percent were for other uses.
