Tributylplumbyl-diaethylamin, also known as tributyl lead diethyldithiocarbamate, is a chemical compound with the formula (C4H9)3PbS2C2H5N. It is an organolead compound that has been used as a pesticide and a fungicide, particularly in the protection of crops against various diseases. Due to its high toxicity and potential environmental and health risks, its use has been restricted or banned in many countries. The compound is characterized by its ability to inhibit the activity of certain enzymes in fungi and insects, which was the basis for its application in agriculture. However, concerns over its persistence in the environment, bioaccumulation in the food chain, and the associated health hazards have led to a decline in its usage.
