Extract

In 1964, 89 percent of the citrus acreage in the U.S. was treated with pesticides. The percentage increased to 97 percent in 1966. Total expenditures for pesticides during the two years were 13.8 and 21.3 million dollars, respectively. Expenditures on a per acre basis were $12.74 and $18.82, respectively, in these years. The trend in pesticide use on citrus pest control has been upward.

The increased usage indicates that pesticides are recognized by growers as important inputs to increase output and/or improve fruit quality. The negative side effects of pesticides on the environment are also being increasingly recognized.
