Summary: The herbicide N‐(3,4‐dichloropxhenyl)‐propionamide (propanil) and a metabolite of propanil, 3,4‐dichloroaniline (DCA), were mixed with Nixon loam soil which was subjected to moisture and air‐drying treatments. Degradation of propanil was altered by subjecting the treated soil samples to storage conditions of moisture, drying and chloroform. The peroxidase activity in fresh soil was very low when soil samples were collected during the cold season. The amount of 3,3′,4,4′‐ tetrachloroazobenzene (TCAB) produced from DCA increased with a simultaneous increase in the peroxidase activity in preincubated soil where carbon and nitrogen sources were added.
