New York AGRICULTURAL EXPERIMENT STATION. 129 
_ Experiment No. 47.— In this experiment there was a quite severe 
attack of late blight. We made two examinations during the 
season. On July 24 we found late blight just beginning to 
appear on the unsprayed rows. On September 7 there was a 
marked contrast between the sprayed and unsprayed rows — the 
former still retained most of their foliage while in some places 
the latter were almost bare. 
_ Two nozzles per row were used in the last three sprayings, 
when the quantity of bordeaux applied was about 60 gallons | 
per acre. 
Experiment No. 48.—A\though the field was sprayed three times 
the results obtained in this experiment should be credited to 
two sprayings, because no check rows were left until after the 
first spraying. Mr. Cook reports that there was only a trace 
of blight on the unsprayed rows and not much contrast in ap- 
pearance between the sprayed and unsprayed rows. Neither 
was there any rot among the tubers and absolutely no damage 
from “bugs” anywhere in the field. 
The expense account included the following items:

Experiment No. 50.— When we saw this experiment on August 
20 there was already considerable contrast between the five un- 
sprayed rows and the adjacent sprayed ones owing to the more 
severe attack of late blight and flea beetles on the unsprayed 
rows. Evidently Mr. Mannix did a fairly thorough job of spray- 
ing and it is surprising that the gain from spraying was so small. 
The total expense of spraying, for labor and materials, was $12. 
Experiment No. 51.—The sprayed rows held their foliage a 
week or ten days longer than the unsprayed ones. 
Experiment No. 52.— The yields given in Table XVI are for un- 
sorted potatoes. Mr. Gott reports that there was little if any 
blight in his experiment and that there was scarcely any differ- 
ence in appearance of the foliage on the sprayed and unsprayed 
rows. Concerning the expense of the spraying Mr. Gott states 
-that the materials cost $18 and that the labor amounted to 
5
