PRACTICAL GARDENING 



and destroyed if sprayed with a strong solu- 

 tion of lime and sulphur when the tree is 

 dormant. This solution is at the strength of 

 one to eight which means that one quart of 

 lime sulphur should be mixed with eight quarts 

 of water. If this strong solution is applied 

 after growth has begun the buds are destroyed. 



If the flat or round head borers are found 

 working in the bark, which is evidenced by a 

 hole in the bark and a little sawdust under it, 

 follow the borer in his furrow by cutting into 

 the wound with a sharp knife, and destroy the 

 insect. Plugging the hole with soap or lime 

 is riot satisfactory. 



As soon as the foliage appears, the tent 

 caterpillar starts his destructive work by eating 

 the leaves. At the same time the apple scab, a 

 fungous disease puts in its appearance. Both 

 may be destroyed at one time. Spraying with 

 lime sulphur one tp forty, will check the scab; 

 but adding to this solution, three pounds of 

 arsenate of lead to every fifty gallons of solu- 

 tion will also destroy the caterpillar.
