Pesticide Use on Fall Potatoes in the North Central Region, 1979

摘要

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.
