THE PURPLE RASPBERRIES 



Pests 



The pests of purple raspberries are those 

 of red and black varieties (see page 45). 

 Mosaic is the most serious trouble, and Colum- 

 bian has been ranked with the Cuthbert red 

 raspberry in susceptibility to this disease. 

 Care should be taken to secure disease-free 

 stock for planting, and any diseased plants ap- 

 pearing in the plantation should be promptly 

 dug out and destroyed. 



Harvesting 



Purple canes usually outyield other types 

 of raspberries, and they ripen late. The ber- 

 ries are soft and perishable, and should be 

 handled with care. Small receptacles should 

 be used in harvesting to prevent crushing of 

 the bottom berries and they should be placed 

 in a cool, well-ventilated place as soon as 

 possible.
