Excerpt from Insects and Insecticides
In order to intelligently apply insecticides, and to be able to judge whether one remedy or another will be more effective, it is necessary to understand something of the habits of the different insects attacking plants. Many insects, like caterpillars, grasshoppers, and beetles, devour the foliage, while others, such as scale insects, plant lice, squash bugs, etc., injure the plant by inserting their sharp beaks into its tissue and sucking the sap from beneath the surface. Insects of the first class can nearly always be destroyed by means of poisons, such as paris green and various forms of arsenates. Those of the second class, or sucking insects, are unaffected by these poisons and must be killed by contact sprays, such as kerosene emulsion, whale-oil soap, crude-oil mixtures, or the lime-sulphur-salt remedy. Another class of insects, and which none of the above remedies will reach, are those which burrow into the bark and trunk of trees. These must be treated mechanically - dug out, and barriers or repellants provided to prevent them from regaining entrance into the trees. In the following pages the most successful remedies are given, but, under certain climatic conditions or in abnormal seasons, other steps may become necessary and advice from the State Commission of Horticulture should always be obtained in cases where any doubt exists.
It should be remembered that the successful application of remedies is dependent upon the exercise of proper judgment. It is essential to first positively identify the insect to be destroyed, then to know the most effective remedy to use, and finally to apply it at the proper season. Promptness, thoroughness, and persistency, combined with good judgment, are the essential factors necessary for the successful application of insecticides.
This office is at all times glad to render any assistance possible in determining the identity of insects and in advising as to the remedy to be used for their control.
