SOIL AND CULTURAL CONDITIONS. 



The soil was heavy clay loam plowed in the fall and again in the 

 spring. The previous crop was a light one of peas and oats. The 

 field sloped toward the north sufficiently to afford excellent sur- 

 face drainage. Planting was done May 22 and 23, the seed being 

 of the variety Rural New Yorker No. 2. Furrows were opened 

 with a plow and the seed pieces dropped by hand 15 inches apart 

 the distance being determined by a gauge-rod marked at intervals 

 of 15 inches. Each row received 14 pounds (500 lbs. per acre) of 

 a complete chemical fertilizer which was scattered in the open 

 furrow by hand as uniformly as possible. With the exception of 

 one light hoeing the cultivation was all done with a horse 

 cultivator. 



PREPARATION AND APPLICATION OF SPRAY 



MIXTURES. 

 The bordeaux mixture used contained six pounds of copper 

 sulphate and six pounds of unslaked lime in each fifty gallons 

 (6-6-50 formula). 



The concentrated lime-sulphur solution used was taken from 

 two different lots which had been prepared for use in the Station 

 orchard. Both lots were made by the Geneva Station formula: 



Lime (90 per ct. pure) 40 lbs. 



Sulphur (high grade, finely divided) 80 lbs. 



Water 50 gals. 



One lot had a density of 23° B. the other, 24° B. 



Both were diluted at the rate of two gallons of the concentrated 

 solution to fifty gallons of water. This is approximately the dilu- 

 tion recommended for orchard spraying, namely, 1 to 40 when the 

 density of the concentrated solution is 32° B. 



The lead benzoate used was in the form of a white paste which, 

 according to the manufacturer, was 65i per ot. water. Three 

 pounds of this paste (= 1 + lbs. dry lead benzoate) were first 

 thoroughly stirred into about two gallons of hot water and after- 

 ward diluted to fifty gallons.
