d-d mixture
"A mixture of 1,2-dichloropropane, 1,3-dichloropropene and other chlorinated hydrocarbons. It has been used as a soil fumigant nematicide, insecticide, herbicide and fungicide. The 1,2-dichloropropane component was relatively inactive as a nematicide at concentrations used in agricultural fields and the mixture is now obsolete as a pesticide."
