New YorK AGRICULTURAL EXPERIMENT STATION. Zar 
THE OGDENSBURG EXPERIMENT. 
Conducted at Ogdensburg, N. Y., by Andrew Tuck, who 
sprayed five and one-half acres of potatoes seven times on the 
following dates: July 17, 24, 31, Aug. 10, 19, 29 and Sept. 7. 
The sprayer used was a one-horse, four-row “ Aspinwall ” 
sprayer carrying one nozzle per row. The bordeaux was of 
the 5-5-50 formula made with water pumped by hand from a 
well within a few rods of the field. Paris green (two pounds 
to 50 gallons) was used with the bordeaux in the first four 
sprayings. The three check rows also were treated with paris 
green four times on the same dates. The writers did not see 
this experiment until digging time. Mr. Tuck reports that 
by: Aug. 10 the unsprayed rows were markediy inferior to the 
sprayed ones owing to the ravages of some kind of blight. 
He thinks it was not due to dry weather. The unsprayed 
rows were not injured by bugs or flea beetles. No rotten 
tubers were found at digging time. 
The expense account contained the following items:

The test rows. were of the variety Rural New Yorker No. 2. 
They were 586 ft. long by 33 in. wide. The yields were as 
follows: 
Two sprayed rows, 486 Ilbs.=98.2 bu. per acre. 
Middle unsprayed row, 66 Ibs.==29.7 bu. per acre. 
Gain, 68.5 bu. per acre. 
Potatoes being worth 80 cents per bushel at time of digging 
the test rows (Oct. 15) the market value of the gain was 
$54.80. After subtracting the expense of spraying, $5.22 per 
acre, there remains a net profit of $48.58 per acre.
