710 Report oF THE HorrTicuLTURIST OF THE 
three sprayings after the fruit buds begin to open and before the 
blossoms open are better than two sprayings during the same 
period. It will be noticed that the highest prices both for sprayed — 
and unsprayed fruit were obtained for the pears grown in that 
part of the orchard where the Seckels were sprayed five times. 
This may be partially accounted for by the fact, noted frequently 
during the season, that the attacks of the scab were not so 
severe on the unsprayed trees in this part of the orchard as they 
were in that portion where the Seckels were sprayed six times, so 
that the two methods of treatment are not in this case strictly 
comparable. Comparing the gain per hundred trees computed 
from the highest prices received for the sprayed fruit_it is seen 
that with trees sprayed six times the gain is $577 while with 
the trees sprayed five times the gain is $566, making an increase 
of eleven dollarsapparently due to the extraspraying. This increase 
would more than pay for the cost of the extra spraying, but it is 
doubtful whether the extra spraying should be credited with this 
gain, and the indications are that it should not. A heavy rain 
storm followed the first spraying and it is possible that the effect 
of the first treatment was consequently much less than it would 
have been had the weather remained fair. On the whole it may still 
be considered doubtful whether it is expedient to spray more than 
twiceafter the fruit buds begin to open and before the blossoms open. 
Inconclusion it may be said that both the Seckel and the White 
\ 
Doyenné pears are varieties especially subject to the attacks of — 
the scab fungus and, therefore, as previously stated, the large 
gains resulting from their treatment, as shown in these experi- 
ments could not be expected to result from spraying every other — 
variety. Yet the fact remains that the fruit and foliage of many 
of the varieties grown in New York State pear orchards suffer 
considerable damage each year from the fungous diseases which 
may be successfully treated by spraying with the Bordeaux mix- 
ture and also from insect foes that may be treated at the same 
time with Paris green. It is undoubtedly true that tens of thou- 
sands of .dollars might be saved annually to the New York pear 
growers by the universal adoption of the method of treatment 
which is here shown to be very successful in preventing the depre- 
dations of some of the worst insect and fungous enemies of the 
pear.
