Qarden Insect Control 
An understanding of the different types of insects that attack 
garden plants and the proper insecticides to use in the method of 
affecting control will be extremely helpful to the average gardener. 
In fact insect damage to garden plants In most cases may be less¬ 
ened to the extent of complete control if one has an understanding 
of insecticides and their proper application. It is said that insects 
are man’s worst enemy. This, of course, we cannot prove. We know, 
however, quite well, that they are extremely destructive In the garden. 
Here we will discuss briefly insects and insecticides In general. 
Garden insects in general are divided into two classes, sucking 
and chewing. In the sucking class are such as aphis, thrip, scale, 
mealy bug, etc. These are also what we call body breathers. They 
take in their oxygen through the pores of their body. Chewing in¬ 
sects are various species of worms, caterpillars, beetles, etc. that 
actually eat the leaves of our garden plants. 
Insecticides may be classified Into three groups, fumigants, such 
as Nicotine, Cyanogas, Carbon Bi-sulphide, Sulphur, etc. Contact In¬ 
secticides, which consist of oil sprays, Lime and Sulphur, Pyrethrum, 
Oil Soap, etc. Stomach poisons consisting of Lead Arsenate, Calcium 
Arsenate, Paris Green, Derris, Fluorine, etc. 
Fumigants and contact Insecticides are used in the control of suck¬ 
ing insects or body breathers. The stomach poisons are used In af¬ 
fecting control of the class known as chewing or eating insects. 
In some cases some of the insecticides above referred to serve 
two purposes. In other words, they kili by contact and also If con¬ 
sumed. These materials may, under the circumstances, be used to do 
a double job. If there happens to be both sucking and chewing in¬ 
sects present it is possible to affect control of both in one application 
of this type of insecticide. The best known of these insecticides at 
the present time are Fluorine, Derris and Pyrethrum. 
At the present time there is considerable activity on the part of 
our national and local agricultural authorities in carrying out what 
might be termed as “an educational campaign’’ familiarizing both 
home and commercial gardeners with the merits of what we call 
“non-poisonous materials,” outstanding among these being Pyrethrum 
and Derris. While compounds made up of these materials are as yet 
not so well known as the old-fashioned arsenicals and other types of 
insecticides even so, being as they are, toxic to both crewing and 
sucking types of insects, in addition being considered non-injurious 
to people or animals, they are becoming increasingly popular and will 
no doubt continue. We recommend them very highly. 
SUMMARY: First consideration—in selecting the proper spray 
materials, is to determine the type of insect that you wish to control, 
whether it is of a sucking or chewing species. If both appear to be 
active use one of the dual purpose materials such as above referred 
to, the compounds of Pyrethrum or Derris. It is in many instances, 
as above outlined, advantageous to treat for the two types of insects 
at the same time. If it is determined that only the sucking type of 
insects is to be controlled then any one of the fumigants or contact 
types of insecticides should be used. If the leaves are being eaten 
and it is determined that an insect is doing the damage then any one 
of the stomach poisons above described may be applied with satis¬ 
factory results. 
You will find Insecticides listed In this catalog on pages 85, 86 
and 87.
