NOTES UPON CELERY. 



I. TWO DESTRUCTIVE CELERY BLIGHTS. 



Introductory. 



The celery industry in New York has attained a rapid develop- 

 ment during the past ten or twelve years. It was only a few 

 years earlier that this plant became so extensively cultivated in 

 the favorable region about Kalamazoo, Mich. At the latter place 

 the conditions are such as to form an environment peculiarly 

 salubrious for celery, and the disease question appears not to have 

 forced itself so prominently upon the attention of growers. In 

 other widespread areas, celery is subject to several blights and 

 spots which greatl}?- affect the marketable value of the product. 

 In the growth of this plant there is no little expenditure of labor, 

 and any cause operating to reduce the price of each heart a few 

 cents means the obliteration of the profits of the grower. There 

 is no doubt that with favorable conditions and skillful manage- 

 ment celery is a paying crop, but two fungous diseases, especially 

 prevalent during the past season, threaten the profits of many. 

 Practically, work upon these diseases has just begun, and if at 

 the outset there is given simply a clear exposition of what these 

 diseases are, and their effects upon the plant, it is hoped to secure 

 the cooperation of those interested ; and, in future, work will be 

 undertaken toward definite measures of relief. In this bulletin 

 a general knowledge of the subject will be summarized, and 

 special attention is called to the matter of storage cellars and to 

 the disease last season so prevalent therein. 



A. Early Blight of Celery. 



General Discussion. 



During the latter part of July of the past season, L- A. Clinton 

 called my attention to the destructive effect of a celery disease on 

 the truck lands of R. W. Parr, Ithaca. The plants then badly
