Effects of fungicide iprodione and nitrification inhibitor 3, 4-dimethylpyrazole phosphate on soil enzyme and bacterial properties

84Repeated iprodione applications decreased soil enzyme activities, bacterial biomass and community diversity. DMPP application increased soil bacterial biomass, and relative to iprodione applications alone, extra DMPP application alleviated the toxic effects of iprodione applications on soil bacterial biomass and community diversity. Moreover, bacterial community structure was changed by repeated iprodione applications, alone or together with the DMPP.
