CRANBERRY DISEASES ON THE PACIFIC COAST

blossom spray was applied on August 6, despite the fact that many 
flowers were still in full bloom. Meanwhile the earlier berries had 
almost matured, and it was considered inadvisable to make any 
further applications of spray. ' , ;, ;.:,.: i 
The above account is given in some detail because subsequent 
experience proved that irregularity of growth and blooming is typical 
of cranberries in this section. Some varieties begin blooming earlier 
than others, and the blossoming period is always comparatively long 
drawn out, even in bogs with a single variety of unnorm age and 
The results of storage experiments with berries from these plots are 
shown in Table 1.

r Terries were scooped Oct. 9 to 15, screened Oct. 15, and shipped to San Francisco Calif , Nov 1. The 
[ first sp^a? was applied May 27, when new vine growth was starting, the second (hook stage) Jane 22, 
and the third (after blossom) Aug. 6]

This series of tests was inconclusive because the checks exhibited 
excellent keeping qualities. Some other storage experiments, how- 
ever, brought out more valuable facts. In a test comparing the keep- 
ing qualities of cranberries from bogs (1) sprayed regularly with 
Bordeaux mixture, including two applications in 1922, (2) renewed 
for fireworm but never sprayed, and (3) neither sprayed nor reflowed, 
the results shown in Table 2 were obtained.
