GARDEN GUIDE 



A sucking insect — note 



the formidable beak, 



used to pierce plants 



and extract juices 



Head of biting Insect — 

 note jaws, large com- 

 pound eyes, and the feel- 

 ers near jaws and eyes 



Another lot of insects aire 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 Eiifected. 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 are the 

 easiest to control. 

 Do not be over 

 worried by insects 

 — ^merely take the 

 time required for 

 any worry and use 

 it to apply effec- 

 tive insecticides. 

 As in medicalwork , 

 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 Uce. 

 Dish water will often keep 

 them nicely in control. 



Lime Sulphar. Useful for 

 blister mite, San JosS and" 

 other scales applied when trees 

 are resting. 



Emulsions aie near solutions of some oil and a soap solution. 

 Good for plant lice and scale insects. Kerosene emulsion consists of: 

 Hard, soft, or whale-oil soap, quarter pound; water, two quarts; kero-

 garden syringe. Be sure to buy a good 

 article to begin with; it pays. The lower 

 figure shows a brass vaporizing sprayer. 

 This is just what is needed for applying 

 liquid insecticides and fungicides
