Increase in yield due to spraying three times, 107 bu. per acre. 
Increase in yield due to spraying five times, 119% bu. per acre. 
From the combined attack of flea beetles, tip-burn and late 
blight the unsprayed rows died fully two weeks earlier than the 
sprayed ones. Spraying reduced the loss from rot at the rate of 
41 bushels per acre. There was no subsequent rot in storage.

Increase in yield due to spraying five times, 82 bu. per acre. 
Late blight caused no injury in this experiment and there was. 
not even a trace of rot. Flea beetles and early blight were the 
enemies fought. 
DETAILS OF THE TEN-YEAR EXPERIMENTS IN 1906. 
SOIL, PLANTING, CULTIVATION, ETC. 
At Geneva.— The plat of land used was the same as that used 
for this experiment in 1904. The soil was a heavy clay loam 
containing some gravel. The surface drainage was good. During 
the season of 1905 it was seeded with red clover. It was plowed .- 
“in the fall of 1905 and again in the spring of 1906.
