Ripe rot {Glomerella rufomaculans (Berk.) Spaul. & von 

 Schrenk) . — This disease is caused by a fungus identical 

 with that causing the ripe rot of the apple. The treatments 

 already recommended for other diseases will also prove 

 efficient here. 



European canker (Nedria cinnabarina (Tode) Fr.), 

 (Nedria ditissima Tul.). — This canker is readily distin- 

 guished from the ordinary cankers produced by Sphaeropsis 

 or Glomerella by its brilliant red or cinnamon-colored 

 pustules scattered abundantly over the affected areas. 

 While cankers due to each of these fungi have been 

 collected upon quince in America, no case of serious injury 

 is known. 



Pale rot {Phoma Cydonioe Sacc. & Schulz.). — This 

 disease is second only to the black rot in prevalence and 

 destructiveness. The rot begins as a pale soft spot, from 

 which the skin can easily be removed. This spot soon 

 wrinkles, the skin ruptures, and through the ruptured 

 places short tufts of fungous threads develop. These small 

 spots are at first colorless, but they soon turn to a pale blue. 



The treatment is the same as for sphaeropsose. 



Hypochnose. See apple.
