CRANBERRY DISEASES ON THE PACIFIC COAST 27 
Cold storage at an average temperature of 32° to 34° F. failed to 
prevent the development of rots, particularly over a period of several 
months. 
Wet weather at picking time, and especially storing berries while 
still wet, increased the percentage of storage rot. 
In more than 3,200 cultures from individual rotted cranberries, 
end rot, caused by Fusicoccum putrefaciens Shear, was found to be 
decidedly the most important rot. Practically all fungi known to 
rot cranberries elsewhere were found in cultures made from Pacific 
coast berries. 
At intervals during the growing season 1,000 cultures were made 
from green berries. Infection by storage-rotting fungi was found to 
take place chiefly during or immediately following the blossoming 
period. Infection usually occurred on the blossom-end half of the 
berry.
