GARDEN GUIDE 



Another lot of insects are borers. They burrow into the stalks, 

 the bark and solid wood of branches, and even the trunks of trees. 

 The fruit trees are especially attacked by these borers. Peaches, 

 Apples. Currants, Gooseberries, Raspberries, Blackberries, Roses, 

 China Asters, Squashes and many other plants are so affected. They 

 must be dug out. Insecticides are hard to apply for any good effect. 



Other insects 

 prefer the leaves 

 and buds of plants. 

 This class is the 

 easiest to control. 

 Do not be over 

 worried by insects

 tive insecticides. 

 As in medical work, 



there is no panacea for all ills, but it is not dangerous to 



make one general sweeping statement about their control. 



It is this: Sucking insects are seldom poisoned by insecticides; their 



breathing pores along the sides of their bodies must be touched and 



filled with the fluid; they are controlled by contact insecticides. Chew- 



ing insects greedily eat the leaves which, if covered with a poison, will 



kill them. 



INSECTICIDES. The following are good contact insecticides and 



are effective against sucking insects such as the various scales, plant 



lice, blister mite, thrips. 



Soap Solutions. A fish oil 



soap is best, but white soap 



can be used to make a good 



spray. Useful for plant lice. 



Dish water will often keep 



them nicely in control.
