The dissipation of carbendazim and chloramphenicol alone and in combination, and their effects on soil fungi:bacteria and soil enzyme activities were investigated. The results revealed that carbendazim dissipation was little affected by chloramphenicol, whereas chloramphenicol dissipation was found to be retarded significantly by the presence of carbendazim. The inhibitory effect of carbendazim on fungal:bacterial ratio and chloramphenicol on neutral phosphatase was enlarged by the presence of chloramphenicol and carbendazim, respectively. The increase in soil catalase and urease activities caused by carbendazim was partially eliminated by the presence of chloramphenicol. Little interaction between carbendazim and chloramphenicol was observed for their influence on soil invertase. The results obtained in this study suggested that combination of fungicide and antibiotic may alter their individual behavior in soil, and their effects on soil enzymes.
Keywords:carbendazim; chloramphenicol; soil enzyme; selective inhibition respiratory; community structure
