Inorganic Insecticides

Inorganic Insecticides are compounds that are not carbon based. They are stable chemicals which do not evaporate and are frequently soluble in water.  Arsenical compounds such as calcium and lead arsenate were frequently used insecticides prior to the wide-scale development of synthetic-organic insecticides which began in the 1940s.  Other examples of inorganic compounds with insecticidal properties are sodium fluoride, sodium silicofluoride and boric acid.  These insecticides are not used in modern production agriculture.
