Pesticide Use on Fall Potatoes in the Northeast Region, 1979

摘要

A survey of pesticides used in fall potato production was conducted by the U.S. Department of Agriculture in 1979. Information is reported for Maine, New York, and Pennsylvania. An estimated 3.5 million pounds (active ingredient) of pesticides were used. Of the 188,500 acres planted to potatoes in the Northeast region, at least 96 percent were treated with a herbicide, fungicide, and/or insecticide. Almost 2.5 million acre-treatments of pesticides were made in 1979, averaging 1.4 pounds (a.i.) per acre-treatment. Coefficients of variation were calculated for acres treated with specific pesticides.
