In 1979, grape growers in Pennsylvania and New York applied 496,000 pounds of pesticides (active ingredients) in 234,520 acre-treatments. Of the total quantity, 240,600 pounds were fungicides, 134,300 pounds were insecticides, and 121,200 pounds were herbicides. Approximately 38 percent of the acre-treatments were mixes of insecticides and fungicides. Coefficients of variation were computed for acres treated with specific pesticides and mixes of pesticides.

Note
In cooperation with New York State Agricultural Experiment Station, Geneva, N. Y. The growers interviewed in the 1979 Grape Pesticide Use Survey were randomly selected from lists of growers. The sample was stratified by acreage so that the medium and large vineyards were sampled more heavily than the smaller vineyards. The counties in each region were: western Pennsylvania - Erie; western New York - Cattaraugus, Chatauqua, Erie, and Niagara; Finger Lakes - Monroe, Ontario, Schuyler, Seneca, Steuben, Yates, and Wayne. Enumerators employed by the State Statistical Offices personally interviewed the growers. Of the 304 growers selected, only 16 (5 percent) were inaccessible. The data for each stratum were expanded by the inverse of the sampling ratio at the stratum level and summed to estimate totals for the producing region.
