AbstractTo select safe and efficient wheat seed treatment agents，the Zhenmai 12 was used as the test material and 5agents were selected， including 27% difenoconazole·fludioxonil·thiamethoxam FS，with 6 treatments designed as follows： 27% difenoconazole·fludioxonil ⋅ thiamethoxam FSat 6mL/kg （treatment 1）， 32% tebuconazole·imidacloprid FLS at 7 mL/kg （treatment 2）， 11% pyraclostrobin·triticonazole FLS at 0.75mL/kg （treatment 3）， 24% difenoconazole·fludioxonil·thiamethoxam FS at 1O mL/kg （treatment 4）， 5% tebuconazole FSC at O.8 mL/kg （treatment 5），and an untreated control （CK）. Wheat emergence time，emergence rate，as wellas the occurrnce of aphids and sharp eyespot ineach treatmentwereinvestigated，andthecontroleficacyof theagents wascalculated.Theresultsshowedthatall5 agents prolonged wheat emergence timeby1-2 days. Compared with CK，treatment 3 significantly improved the emergence rate 15 days after sowing，and the difference compared with CK was statistically significant （ P <0.05）， while no statistically significant differences （ P>0.05 ）were observed between the other treatments and CK.For wheat aphids， treatment1 demonstrated the highest control ficacy，followedby treatments2 and4.For wheat sharp eyespot， treatment 1 also showed the best control efficacy，followed by Treatment 4.In conclusion， 27% difenoconazole·fludioxonil·thiamethoxam FS （treatment 1） hadarelativelysmallimpact onwheat emergence time，improved the emergencerate to acertain extent，and effctively controlledboth wheataphids and sharp eyespot，making it suitable for promotion and application as a wheat seed treatment agent.
