SPRAY CHART 



Insect pests and plant diseases have increased and spread so much during the past few 

 years, that spraying has become as much a part of gardening as digging the ground. 



Insect pests are divided into two classes: the chewing or eating insects and the sucking 

 insects. The chewing insects (caterpillars, beetles, etc.), can be destroyed by applying 

 poison to the surface of the plants. For sucking insects (aphis and plant lice), a contact 

 spray that clogs up their breathing pores or gives off a poisonous gas must be used. 



Plant diseases (scales, blights and mildews), require other specially prepared sprays. 

 We give below a list of crops most seriously troubled with insect pests and diseases, and 

 proper spray for their control.

Ants 



Ants are not in themselves injurious to plants, but they do harbor, protect and transport 

 the aphis, and therefore should be exterminated. Antrol is the best remedy. 



Cut Worms, Grasshoppers and Snails 



Cut Worms, Grasshoppers and Snails do a vast amount of damage, and, as they cannot 

 be reached by ordinary sprays, a poison bait must be used. We have found Snarol to be 

 very effective against these pests. 



Garden Friends 



The following insects, etc., eat many kinds of garden pests and should not be killed: 

 LADY BUGS, CBICKETS, CENTIPEDES, TOADS, SNAKES, BIRDS. 



Dormant Spraying 



All trees, shrubs and bushes will be benefited by spraying with either Scalecide or 

 Lime-Sulphur solution during late Winter and early Spring, when they are dormant. These 

 sprays not only control many blights, scales and diseases, but also kill the eggs of many 

 insects. 



How to Spray or Dust 



Successful combating of insects and diseases depends upon the thorough application 

 of the spray or dust. Both upper and under sides of leaves must be covered and in 

 the case of the more tenacious insects, such as Aphis, spraying must be continued at fre- 

 quent intervals until control is obtained.
