Decay, averaging 5.0 percent per carlot showing decay, was found 

 in 2,254 carlots, or 69 percent of those inspected. Distribution of 

 decay by types was as follows: 



Distribution Distribution 



Carlots 

 Kind of decay: (number) 



Gray mold rot 1,549 



Rhizopus rot 1,004 



A summary of all grape inspections is presented in table 5. Decay 

 per carlot inspected ranged from 1.1 to 10.9 percent and averaged 3.4 

 percent for the entire period. About two-thirds of all spoilage was 

 caused by gray mold rot. The loss from rhizopus rot was more than 

 twice as great as from the blue mold rot. Least decay occurred from 

 March through September.
