206 THE BRAMBLES 



By fall they have reached the root, where they remain over 

 winter. This insect is held in control by cutting off the 

 tip of the canes below the girdled point and burning them. 

 Spraying is not effective against this kind of an insect. 



SPRAYING OUTLINE FOR THE BRAMBLES. 



When the new canes are 8 to 10 inches high begin spray- 

 ing with 4-4-50 Bordeaux mixture and repeat at intervals 

 of every two or three weeks throughout the growing season. 

 If worms or slugs appear and destroy the foliage by eating it, 

 add 2 pounds of arsenate of lead to 50 gallons of spray. 

 After the fruiting season has passed, thoroughly inspect the 

 canes, cut out and burn all those which are irregular in 

 growth, weak or infected with galls, tree cricket eggs or 

 stem borers.
