1,2-Dibromo-3-chloropropane (DBCP) was used in the past as a soil fumigant and nematocide on crops; it is no longer used except as an intermediate in chemical synthesis.

DBCP is a colorless liquid, denser than water, that can be tasted in water at very low concentrations. It is an organochlorine compound and it is a manufactured chemical, not naturally found in the environment. It was used as a soil fumigant in the control of nematodes (a parasite harming crops).

Containers of DBCP-contaminated protective devices or work clothing which are to be taken out of change rooms or the workplace for cleaning, maintenance or disposal shall bear labels with the following information: CONTAMINATED WITH 1,2-Dibromo-3-chloropropane (DBCP), MAY CAUSE CANCER.
