At high concentrations barban, its commercial formulation Carbyne or the formulating solvent, initially increased soil respiration. Increased respiration due to Carbyne or the solvent was accompanied by bacterial proliferation in response to the organic carbon of the solvent. There was no initial increase in bacterial population in barban‐treated soil. Soil respiration was inhibited after Carbyne treatment during the later stages of incubation (up to 220 days) despite a bacterial population larger than in untreated soil. Barban and Carbyne depressed the rate of glucose utilization and increased phosphatase activity in soil; it is suggested that barban interferes with the respiratory processes of soil micro‐organisms. Low concentrations (2 parts/10 6 ) of 3‐chloroaniline were detected in soil treated with either barban or Carbyne. Carbyne and its ingredients also affected the growth and physiological properties of soil bacteria and fungi.
