FURTHER STUDIES OF THE ROTS OF STRAWBERRY FRUITS. 13 
Botrytis sp. is characteristically a field rot of strawberries. It is 
most abundant and serious in the field under conditions of excessive 
moisture. 
Berries affected with Botrytis can be recognized at the time of 
picking and packing and should not be included in fruit intended 
for market. 
Although Botrytis is able to grow at low temperatures and fre- 
quently produces abundant aerial hyphse on strawberries in refrig- 
erator cars, its growth on ripe berries is so slow that it is of minor 
importance as a cause of rot in transit. 
It is evident that the entrance of Rhizopus into strawberries and 
the production of leak are not dependent upon previous infection by 
Botrvtis.
