Difenoconazole and imidacloprid are key components of seed-coating agents, which alter soil microbial community structure function after application. Existing studies mainly focus on the environmental effects their spraying application, while research impacts ecosystem when used as agents is relatively limited. Through field experiments, this study systematically evaluated compared difenoconazole seed coatings wheat rhizosphere communities ecological functions by measuring enzyme activities, employing 16S rRNA ITS high-throughput sequencing technologies predicting KEGG functional pathways. The results showed that significantly reduced bacterial diversity, particularly under high-dosage treatment (0.18 g a.i./kg seed), with a 5.80% decrease in diversity day 30. This most strongly inhibited phyla Bacteroidota Myxococcota, maximum reductions 23.87% 63.57%, respectively. However, abundance Actinobacteriota increased, increase 38.53%. Additionally, fungal increased both treatments. Both altered from days 20 to 60, recovery occurring 120. Furthermore, pathway analysis revealed seed) activated pathways such cell motility, signal transduction, membrane transport, whereas standard dosage (0.12 exhibited metabolic suppression. elucidates dynamic agent application communities, providing theoretical support for rational pesticide use optimization agricultural strategies.
