DictionarySeedichlorodiphenyltrichloroethanedicophane
di·chlor·o·di·phen·yl·tri·chlo·ro·eth·ane (DDT), (dī-klōr'ō-di-fen'il-trī'klōr-ō-eth'ān), An insecticide that came into prominence during and after World War II. For a time it proved effective, but insect populations rapidly developed tolerance for it, hence much of its original effectiveness has been lost; general usage is now widely discouraged because of the toxicity that results from the environmental persistence of this agent. Synonym(s): dicophanedicophane (di'ko-fan) A powerful insecticide now rarely used because of its toxicity. Synonym: chlorophenothane; DDT |
