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.
氯虫苯甲酰胺和咯菌腈使用量的增加引发了人们对其残留以及对土壤微生物群落影响的担忧，凸显了一个亟待关注的问题。本研究调查了氯虫苯甲酰胺和咯菌腈处理后玉米中的残留动态，以及它们对土壤酶活性和微生物群落结构的影响。高效液相色谱 - 串联质谱（HPLC-MS/MS）分析表明，联合施用后土壤中氯虫苯甲酰胺和咯菌腈的残留量显著降低，尤其是氯虫苯甲酰胺。这种施用导致脲酶和蔗糖酶活性暂时降低。此外，土壤微生物群落的高通量测序显示，在施用咯菌腈期间，[此处原文缺失具体微生物名称]的相对丰度下降，而[此处原文缺失具体微生物名称]和[此处原文缺失具体微生物名称]增加。另外，施用氯虫苯甲酰胺后，[此处原文缺失具体微生物名称]和[此处原文缺失具体微生物名称]显著增加。与单独施用相比，氯虫苯甲酰胺和咯菌腈的联合施用不仅减少了有害微生物的数量，还降低了土壤中的残留水平。这最终提高了防治措施的效果并促进了环境相容性。
