FUETHEE STUDIES OF THE EOTS OF STEAWBEREY 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 

 Botrytis.
