Heald, f. D., The Black -Rot of Apples due to Sclerotinia fruc- 

 iigena. (Nebraska Agr. Expt. Stat., Report XIX. o. 82—91. 

 2 pl. Feb. 1906.) 



The author has carefully worked out a black-rot of apples, and 

 found it caused by Sclerotinia fructigena, which has ordinarily 

 assumed to be the cause o! a brown rot of apples, peaches etc. 

 The fungus was isolated and grown in pure cultures, with which 

 appies were inoculated. The color of the rot was brown at first, 

 then latter a black color. Hyphae and conidial tufts either did not 

 appear on the surface at all or only rarely. Apples kept in a fairly 

 dry air at a temperature lower than room temperature showed most 

 frequently the typical black condition. 



The conditions favoring the rotting were as follows: an abun- 

 dance of moisture; and injuries, such as bruises, insect punctures, 

 scabbed spots and cracks. Spraying with Bordeaux mixture, with 

 addition of insecticides, and ihe removal of all diseased fruits from 

 the orchard is advised. Hedgcock.
