The avorago spraying and dusting coats per acre, "by areas, for all 

 vineyards included in the study, varied from an average of $13.72 per acre for 

 vineyards studied in Arkansas to 44 coats per acre for Vineyards studied in 

 Niagfira County, N".Y* (table 83.) The lower area costs per acre are due in 

 large part to the fact that nuch of the acrea{^o was not sprayed or dusted. 

 The averages were obtained by dividing the total cost of spraying or dusting 

 the vineyards studied by the total acreage of vineyards. The spraying and 

 dusting costs for la'kansas in 1929 amounted to 22.0 percent of the total cost 

 of growing grapes. Tlio cost of growing gi'apos did not include the cost of 

 harvesting and marketing. In Michigan the spraying and dusting costs amcunted 

 to 11.2 percent and in Girard to 9.7 percent of the total grov/ing costs. 



?n an average, for the vineyards studied in Chautauqua County, N#Y#, and 

 in the Finger Lakes area the spraying and dusting costs were less than $2,000 

 per acre and amounted to less than 3 percent of the total cost of grov/ing grapes* 



^n the average, about one third of the cost of spraying and rttisting wis 

 for labor and for horse and tractor vzork. The cost of the dust and spray ma- 

 materials applied to vineyards amounted to a little more than one third, and 

 the use of the sprayer, duster and other tools, to somewhat less than one third 

 of the total dusting and spraying costb* Another item of cost ?/as interest en 

 the spraying and dusting costs which vai*ied'from c.n average of 1 cent an acre 

 for Niagara County to 27 cents for Arkansas ♦
