The results are so plainly set forth in the diagram that comment is 
unnecessary. 
Fifth treatment (June 25).—Only the trees which were to receive 
seven Sprayings were treated at this time, the work on the others being 
completed. No decided change, as regards injury, from the treatments 
took place since the last spraying. AI] the trees showed more or less 
of the Hntomosporium and seab fungus, but it was too early to form 
any definite opinion as regards the effects of the treatments. 
Sixth treatment (July 15 ).—Aside from the fact that the rusty appear- 
ance of the fruit had increased on all of the treated trees, very little 
change took place between this spraying and the last. The effects of 
the Entomosporium and scab fungus were becoming more apparent, 
in consequence of which it was decided to examine all the fruit at the 
next spraying, for the purpose of obtaining information on the results 
of the treatments. 
Seventh treatment (August 15 ).—The seventh and last treatment was 
made immediately after a heavy rain. The orchard, as a whole, at this 
time was in fair condition. Hntomosporium had caused many of the 
leaves on the untreated trees to fall. This fungus also occurred to a 
considerable extent on the fruit. Scab was not very abundant, cer- 
tainly not to the same extent as the Hntomosporium. 'To obtain infor- 
mation as regards the result of this work, the fruit on each tree was 
counted and the following points noted: 
(1) Total number of fruits. 
(2) Total number affected with scab. 
(3) Total number affected with Hntomosporium. 
The figures obtained by this count enabled us to determine the per- 
centage of fruit affected with Hntomosporium and the percentage af- | 
fected with scab. In making the count, some fruits were found affected 
with both Entomosporium and seab. In such cases, if the specimen 
showed a greater amount of scab than Entomosporium it was referred 
to the former class. If, on the other hand, Hntomosporium predomi- 
nated, it was classified as being affected with this fungus. 
The effects of Hntomosporium and scab on the foliage were also ob- 
served. Finally, careful observations were made on each tree for the 
purpose of determining the injurous effects, if any, of the treatments. 
In the table below (Table 17) the results of the count made to deter- 
mine the total number of fruits, the number affected with scab, the 
number affected with Hntomosporium, and the percentage in each case, 
are given in detail.
