Degradation of chlorpyrifos by two soil fungi Aspergillus niger and trichoderma viride

Two soil fungi, namely Aspergillus niger and Trichoderma viride were evaluated for the degradation of chlorpyrifos. T. viride has been found to be more active, 95.7% of chlorpyrifos degraded in the presence of T. viride as compared to 72.3% in A. niger by day—14. The toxic metabolite of chlorpyrifos, 3, 5, 6‐trichloropyridinol was not detected during the 14‐day incubation period.
