A survey of pesticide use in fall potato production was conducted by the U.S. Department of Agriculture in 1979. Information is reported for Michigan, Minnesota, North Dakota, and Wisconsin. An estimated 2.9 million pounds (active ingredient) of pesticides were used. Growers treated more land with insecticides than with any other pesticide category, 96 percent of the potato acreage. About 2.2 million acre-treatments were made with pesticides using 1.3 pounds (a.i.) per acre-treatment. Fungicides were used in 1.0 million, or 47 percent of all acre-treatments. Herbicides, vine killers, and growth regulators were less important. Coefficients of variation were calculated for acres treated with specific pesticides.

Note
The sample design was a two-stage multiple frame sample. Sample fields were selected from a list of known growers (list frame) maintained by the SSO's. In addition, area tracts (area frame) were selected to insure that all growers had an opportunity to be included in the sample. Sample fields were randomly selected, and the probability of being selected was proportional to field size. The expansion factor for the State was derived by dividing the planted acres by the number of completed questionnaires. Out of 760 sample questionnaires, 528 were completed.
