A FRUIT-DISEASE SURVEY OF WESTERN 
NEW YORK IN 1900.* 
F. C. Stewart, F, M. Rortrs anno F. H. Hatr. 
SUMMARY. 
During the season of 1900 the writers made frequent visits to 
the orchards, vineyards and small-fruit plantations throughout 
Western New York for the purpose of learning what fruit dis- 
eases exist there. The information thus gathered was supple- 
mented by the replies to a circular letter of inquiry which was 
sent to 200 fruit growers. 
The season of 1900 being an unusually dry one, fungous dis- 
eases did not thrive. All kinds of fruit were unusually free from 
disease, Consequently, there are no remarkable outbreaks of 
disease to report. The chief feature of this report consists in 
descriptions of some new or little-known discases and a few new 
facts about the common diseases. Such items of interest are 
the following: Macrophoma on apple (p. 174) and pear (p. 198); 
Cytospora canker of apple (p. 175); “ hairy reot ” of apple (p. 177); 
a disease of apricot (p. 180); brown spot of apricot (p. 181) and 
peach (p. 192); a fall rust of blackberry (p. 182); hail injury to © 
cherry (p. 186) and plum (p. 202); leaf scorch of cherry (p. 188) 
and pear (p. 197); frost injury to grape (p. 189); double peaches 
(p. 195); “little peach ” (p. 191); nursery-cellar disease of peach 
(p. 194); Cytospora on peach (p. 196), plum (p. 201) and apricot 
(p. 181); gumming of plum fruits (p. 203); powdery mildew of 
quince (p. 205); cane knot of raspberry (p. 206); powdery mildew 
of raspberry (p. 208); and cane blight of raspberry (p. 208).
