Effect of Crude Benzene Hexachloride on Wheat Seedlings


THERE are numerous published references to the unfortunate effects of benzene hexachloride on the development of plants, both from seed1–3 and from the tuber4. In only one of these reports, however, is any reference made to the question of the exact identity of the constituent of the crude material which is responsible for these effects3. Of the many isomers and impurities present in the crude material, only the gamma isomer is recognized as important as an insecticide. If the effects of benzene hexachloride on plants are due to some other constituent, the potentialities of the material as an agricultural insecticide may be greatly extended. To settle this question, experiments were begun in March 1948 by treating seed wheat with various preparations and constituents of benzene hexachloride, and observing the effects on germination and development.
