Chlordane

This well-known insecticide was the first member of the cyclodiene class of pesticides introduced in 1945. Other members of this class include Aldrin, Dieldrin, Heptachlor, Endosulfan, and Chlordecone (Keponer). The cyclodienes are persistent insecticides that are very stable in soil and relatively stable to ultraviolet radiation from sunlight. Subsequently, they have been widely used as soil insecticides and for control of termites and soil-borne insects whose immature stages (larvae) feed on the roots of plants. These insecticides are the most effective, long-lasting, economical, and safest termite control agents yet developed. Unfortunately, several soil insects have developed resistance to these chemicals in agriculture, which has resulted in a rapid decline in their use.
