SIMPLIFIED INSECT AND DISEASE CONTROL 
In the garden the difference between success and failure frequently depends upon how effectively the 
many insects and diseases are controlled. 
There are a number of new and more effective spray materials 
available which equip the gardener better in this battle than he has ever been before. 
But equally as im- 
portant as efficient spray materials is an effective and properly executed spray program. 
Spraying should be started early to catch the first insects before they have an opportunity to be- 
come established in great numbers. 
One thorough spraying which catches the first brood in an especially 
susceptible stage may be many times more effective than several applications later. 
As an example, the 
leaf hopper can be controlled most readily in the nymph stage. 
HOW TO SELECT INSECTICIDES AND 
FUNGICIDES 
In selecting an insecticide it is necessary to con- 
sider the cost of the finished spray of effective 
strength. Some material may cost very little per 
pound or gallon compared with another, but be- 
cause it is weak or dilute it will make so much less 
effective spray that the cost is much greater than 
that of the more expensive but more concen- 
trated spray material. =
