into 7 blocks, the sprayed blocks alternating with the unsprayed. 
Block 1 contained 26 trees and the remainder 6 each. Thus. 4 blocks 
were spraved and 3 unsprayed. The spraying schedule is shown in

It was planned to spray block 1 every third day. block 3 every 
fourth day. block 5 every fifth day. and block 7 every sixth day 
beginning when the buds began to swell and continuing until the 
flowers had opened. The treatment was suspended at that time. 
March 19. until the fruit had set, and then resumed. Thereafter the 
spraying was to be continued at intervals of three, four. five, and six 
weeks, respectively, until about two weeks before the fruit was to be 
picked. It will be seen by examining the dates that the spraying 
prior to the setting of fruit was varied slightly hi blocks 1.3. and 5. 
This was due to rainy weather. 
On June 29 the fruits on all the trees were examined and careful 
notes made of then condition. Those which showed no blemishes 
were classed as clean, those but slightly marked as slightly diseased, 
and the remainder as badly diseased. The fruit counts are shown in

The trees in this experiment bloomed lightly and iriegularly, and the 
total number of fruits harvested from each sprayed block is not suffi- 
cient to give any definite conclusions in regard to the relative merits 
of the various spraying schedules:, but the fact that considerably more 
fruit was carried through to maturity on the sprayed than on the 
unsprayed trees indicates that the protecting of the panicles from
