The total expense of spraying was $8.47 per acre or 94 cents 
per acre for each application. : 
The test rows were dug October 10. They were 670 feet long® 
by 3.5 feet wide, 18.45 rows being required to make an acre. 
The yields were as follows: 
Second sprayed row on the south, 687 lbs. marketable tubers. 
Second sprayed row on the north, 702 Ibs. marketable tubers. 
Average of middle two unsprayed rows, 599.5 lbs. marketable tubers. 
Vield, sprayed, 213 bu. 34 lbs. marketable tubers per acre. 
Yield, unsprayed, 153 bu. 36 Ibs. marketable tubers per acre. 
_ Gain, 59 bu. 58 lbs. marketable tubers per acre. 
There was no loss from rot except a few rotten tubers on the 
unsprayed rows. The yield of small potatoes was at the rate of 
20.6 bushels per acre for the sprayed rows and 21.2 bushels per 
acre for the unsprayed. 
At the time of digging the test rows potato buyers at Litch- 
field Station, one mile distant, were offering 45 cents per bushel 
for potatoes.? At this price the gain in this experiment would 
have a value of $26.98. After deducting the expense of spray- 
ing, which was $8.47 per acre, there remains a net profit of $18.51 
per acre. 
THE CORTLAND EXPERIMENT. 
This experiment was conducted by G. H. Hyde, Cortland, N. Y., 
who made a similar experiment for the Station in 1905. The 
* Mr. Dean thinks that a mistake was made in the length’ of the rows. 
He states that in the deed the width of this field is given as 40 rods. When 
the test rows were dug, about one rod at one end was rejected. This would 
make the length 39 rods or 643.5 ft. instead of 670 ft. and the gain from 
spraying somewhat larger. There being no opportunity to remeasure the 
length of the rows it has been thought best to use the original figures. 
* Most of Mr. Dean’s neighbors sold their potatoes in Sayre, Pa., five miles 
distant, at 50 cents per measured bushel, which is equal to about 52 cents 
by weight. Mr. Dean also sold gco bushels there in winter but was unable to 
do so at digging time for lack of time to handle his crop of 3,500 bushels.
