  • Description:
    During the last decade a singularly large increase in the number of chemicals useful in controlling insect and other pests of plants, animals, and man has occurred. Practically all of these new pesticidal chemicals are organic in nature and generally have proved superior to the older inorganic poisons such as lead arsenate, calcium arsenate, and paris green. The initial inspiration for this large increase in the number of new insecticides was the discovery of the insecticidal properties of DDT, one of the most useful of the new materials. This compound was prepared originally about 75 years ago, but it was only during the second World War that the remarkable insecticidal properties of DDT became known. Since DDT can be considered chemically as a chlorinated hydrocarbon it was only natural that other compounds falling in this general class were made and tested for their insecticidal properties. As a result we now have eight or nine chlorinated organic compounds having rather excellent pesticidal properties.
