NEw YorK AGRICULTURAL EXPERIMENT STATION. 169 
Experiment No. 6.—Used one nozzle per row in the first two 
sprayings and two nozzles per row in the last two. The unsprayed 
rows died three weeks earlier than the sprayed ones. 
Experiment No. 7.—The sprayed rows outlived the unsprayed 
ones from two to three weeks. There were quite a good many 
more rotten tubers on the sprayed rows. The expense of spraying 
ten acres five times was $21 for materials and $14 for labor (man 
and team four days) making a total of $35. 
Experiment No. &.—The sprayed rows lived ten days longer 
than the unsprayed ones. The expense of spraying ten acres five 
times was $13.40 for lime and blue vitrol and $17.50 for labor (man 
and team five days) making a total of $30.90. The yields given 
in the table are for unsorted potatoes. 
Experiment No. 9.—The dates of spraying were August 25 and 
September 2 but as the spraying of August 25 was a double one 
it seems proper to consider that the plants were sprayed three 
times. The items of expense for spraying one and one-half acres 
three times were as follows:

Experiment No. 1o.—The bordeaux was applied at the rate of 
30 gallons per acre at each spraying, but Mr. Prole expresses the 
opinion that a larger quantity would have given better results. 
Another season he will go over the rows in both directions at each 
spraying, using about 60 gallons per acre. 
Experiment No. r1.—The dates of spraying were July 8, 14, 
21, August 1, 8, 17 and 28. In the first and last sprayings the 
bordeaux used was of the 5-5-50 formula; in the others it was 
4-4-50. It was applied at the rate of 33 gallons per acre each time. 
Mr. Lyday thinks one additional spraying would have increased the 
yield still further. 
Experiment No. 12.—Seven sprayings were made between July 
1o and September 2. Three unsprayed rows 48 rods long yielded
