The three plots receiving one late application during 1910 and 
IQII gave an average percentage of sound fruit of only 77.47, 
there being a range for individual plots from 57.35 to 93.57. The 
average percentage of sound fruit is approximately midway between 
that obtained from one spraying and the yield of the check trees, 
namely, 77.47. The average benefit accruing from this one spray 
is approximately 10 per cent of the entire yield. The large per- 
centage of end wormy, namely, 12.26, shows that this treatment 
lacks efficiency because of the failure to destroy caterpillars enter- 
ing at the blossom end of the apples. 
Results obtained fromtwo sprayings. This means a treatment 
during the first period, that is within a week or ten days after the 
blossoms fall, and another spraying in the second period, namely, 
about three weeks after the blossoms drop.

The six plots receiving two sprayings during 1909-11 produced 
from 83.45 to 99.54 per cent of sound fruit or an average of 97.65,
