Regulatory Status: The EPA has classified dicofol as toxicity class II - moderately toxic, and toxicity class III - slightly toxic, depending on the formulation. Products containing dicofol bear the Signal Word WARNING or CAUTION, depending on the formulation. Products containing dicofol are designated General Use Pesticides (GUPs).

Chemical Class: organochlorine

Introduction: Dicofol is an organochlorine miticide used on a wide variety of fruit, vegetable, ornamental and field crops. Dicofol is manufactured from DDT. In 1986, use of dicofol was temporarily canceled by the EPA because of concerns raised by high levels of DDT contamination. However, it was reinstated when it was shown that modern manufacturing processes can produce technical grade dicofol which contains less than 0.1% DDT.
