Prothioconazole (PTC) is currently a popular triazole fungicide. In recent years, as the use of PTC has increased, there been growing concern about its environmental and toxicological effects. Here, we studied effect on growth soybean plants further analyzed enzyme activity microbial community rhizosphere soil after treatment through 16S rRNA gene high-throughput sequencing fungal ITS. Changes in structural diversity species richness were measured using Simpson’s index, Shannon’s index Chao1 ACE algorithms. The statistical t-test was applied to test whether values significantly different between two groups. results showed that contents malondialdehyde (MDA) H2O2 increased recommended dose PTC, indicating strong toxic plant growth, thus affecting healthy plants. presence fungi bacteria decreased all three types (black soil, yellow earth red earth), structure also changed (the p-values less than 0.05). Proteobacteria, Actinomycetota, Bacteroidota Acidobacteriota main bacteria, abundance Chloroflexi increased. dominant communities Ascomycota Mortierellomycota. potentially beneficial microorganisms, such Sphingomonadaceae, suggested may be resistant stress by recruiting microorganisms. PICRUSt analysis metabolism-related functions membrane transport pathway bacterial inhibited stress. Spearman correlation revealed weak key taxa variables PTC. Therefore, compared with those community, more likely help resist stress, these groups indirectly under community.
