5. Occurrence in the Nursery. 



The principal nursery regions which I have examined in this con- 

 nection are those in the vicinity of Dansville, Geneva, and Cayuga. 

 While the leaf- blight is 

 the financial bane of seed- 

 ling pears, this leaf-spot 

 is uniformly the fungus 

 monopolist of budded 

 stock after the first year. 

 Budded stock of two years 

 or older is often badly 

 injured late in the sum- 

 mer, and occasionally I 

 have found the leaf-spot 

 to a considerable extent 

 upon one-year stock. Al- 

 though well aware of its 

 presence, nurserymen, as a 

 rule, do not consider this 

 sufficiently injurious to 

 warrant their attention, 

 especially as there is 

 greater difficulty in spray- 

 ing the stock of the second 

 year; but many realize 

 that it would be desirable 

 to spray. Some make a 

 practice of spraying the 

 one-year stock early in the 

 season, but those who do 



this are few, and the fact remains that it suffers less injury than older 

 stock. As to the cause of this apparent immunity, several prominent 

 nurserymen a^ree that with an abundance of room and with the 

 good culture usually given the first year, the plant finds such favor-
