It will be seen from the above tabulation that the yield on plot r 
was light, it ranging per tree from 232 apples to 1571. Approxi- 
mately one-third of this, 34.71 per cent, was perfect fruit, while 
17.32 per cent were affected by scab and 27.26 per cent showed the 
work of the leaf roller. The percentage of wormy apples was high, 
it ranging for individual trees from 19.74 to 43.01 and under the 
conditions obtaining when the first and more important application 
was made this is perhaps not surprising. The high percentage of 
wormy fruit is reflected in the end wormy, this amounting in the 
case of three trees to over 2 per cent and averaging for the plot 1.61 
per cent. There was a large amount of side injury, this varying for 
individual trees from 7.92 to 23.27 per cent. There was also a 
moderate though not excessive percentage of “ shallow ’”’ affected 
apples, this varying for individual trees from 11.81 to 27.09, the 
average for the plot being 18.35 per cent.

The yield for plot 2 was markedly less than that for plot 1, two 
trees producing no apples and the others with an average con- 
siderably less than in plot 1. There is a higher percentage of perfect 
fruit, 40.94 per cent, and a lower percentage of scabby apples, 
15.28 per cent, the latter probably due to the second application. 
There was also less injury by leaf roller and a reduction in the per- 
centage of wormy apples, this averaging for the plot 27.14, indi- 
vidual trees varying from 23.81 to 32.94. There was a higher 
percentage of end wormy, a decidedly lower percentage of side 
wormy, and a slightly less percentage of ‘‘ shallow” affected apples 
as compared with plot r.
