Abstract

The increased use of chlorantraniliprole and fludioxonil has sparked concerns about their residues and impact on the soil microbiome, highlighting an urgent issue requiring attention. This study investigates the residue dynamics of corn after chlorantraniliprole and fludioxonil treatments, as well as their effects on soil enzyme activity and microbial community structure. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) analysis showed a significant decrease in chlorantraniliprole and fludioxonil residues in the soil after combined application, especially with chlorantraniliprole. This application caused a temporary reduction in urease and sucrase activities. Furthermore, high-throughput sequencing of the soil microbiome revealed a decrease in the relative abundance of during fludioxonil application, while and increased. Additionally, and saw significant increases after chlorantraniliprole application. The combined application of chlorantraniliprole and fludioxonil not only decreased the population of harmful microorganisms but also lowered residue levels in the soil when compared to individual applications. This ultimately enhanced the efficacy of control measures and promoted environmental compatibility.
