Insecticidal activity of the pyrethrins and related compounds VIII. Relation of polarity with activity in pyrethroids

摘要

AbstractComparing insecticidal activities of a wide range of pyrethroids with polarities measured by reversed phase, thin‐layer chromatography suggests that there are optimum polarities for potency in bothMusca domesticaandPhaedon cochleariae, and that these optima have closely similar values. The significance of these conclusions is discusse
