DISEASES 



Anthracnose of Raspberry, Blackberry, 

 Loganberry, Etc. 



Gloeosporium venetum 

 H. S. Jackson 



The disease known as anthracnose is a 

 very common trouble of certain varieties 

 of blackberries and raspberries through- 

 out the United States; and in Oregon, at 

 least, the disease is becoming serious 



upon the loganberry as well. This is 

 apparently an American disease, first de- 

 scribed by Burrill in Illinois about 1882, 

 and has often been referred to as caus- 

 ing considerable loss in various sections 

 of the country. It is probably the most 

 serious disease with which the logan- 

 berry grower is likely to have to deal, 

 and in most sections spraying for this 

 disease will doubtless become a regular 

 operation in connection with the culture 

 of this fruit. 



The disease attacks the canes, leaves 

 and the fruit. On the stems the disease 

 produces spots of varying size and color, 

 depending upon the variety attacked. The 

 spots are pale in the center with irregu- 

 lar brown and black (or on the raspberry,
