A summary of all pear inspections is found in table 9. Decay per 

 carlot. inspected ranged from 0.5 to 7.0 percent, with an average of 

 2.5 percent. Blue mold rot and gray mold rot were reported each 

 year and accounted for practically all of the decay. Blue mold rot 

 caused more than twice as much spoilage as did gray mold rot. De- 

 cay was most prevalent in shipments from Oregon and least so in 

 those from California. The least decay was found from July through 

 September. Blue mold rot was most prevalent from December 

 through March and gray mold rot from December through June. It 

 will be noted that all inspections were on western pears.
