Effects of Chlorothalonil Application on the Physio-Biochemical Properties and Microbial Community of a Yellow–Brown Loam Soil

To gain better knowledge of the effects residual chlorothalonil on soil characteristics and microbial communities, we evaluated dissipation different concentrations respiration, enzyme activities, community structure in yellow–brown loam soils. Bacterial fungal communities were examined using traditional plate counting polymerase chain reaction–denaturing gradient gel electrophoresis (PCR–DGGE) methods. Soil properties results DGGE band analysis both used to estimate status ecosystem. The show that has considerable enzymatic structure. In particular, respiration phosphatase activities increased, while saccharase activity, biomass, diversity decreased by increasing levels treatment. Correlation analyses revealed application was significantly correlated with change urease sucrase culturable bacteria, fungi biomass. We conclude is directly related
