| 中文摘要: |
| 近年来, 小麦茎基腐病对小麦生产造成的影响日益严重, 亟须探索新的防控策略。为此, 在2023年-2024年对鲁西南地区的邹城市开展了该病害的防治研究示范。研究选取了7种新型复配种子处理悬浮剂(FS), 对小麦种子进行播前包衣处理, 并在返青期进行40%丙硫菌唑·戊唑醇悬浮剂(SC)根部喷淋, 以评估其对小麦茎基腐病的防控效果。田间试验结果表明, 27.2%氟环菌·咯菌腈·噻虫嗪FS对小麦苗期生长性状的影响较小, 并在苗期表现出较强的防控作用。结合返青期喷药处理, 该药剂展现出最佳的病害控制及增产效果, 其对灌浆期茎基腐病的防效达80.89%, 增产率为15.53%。其次是10%甲·戊·嘧菌酯FS, 其防效为77.07%, 增产率为13.94%。试验结果表明, 种子包衣结合返青期喷施杀菌剂是防止小麦茎基腐病扩展的有效手段。该研究为本地区小麦茎基腐病的防控提供了新的药剂选择和实践参考。 |

| In recent years, Fusarium crown rot has increasingly threatened wheat production, highlighting the need for novel control strategies. To address this issue, field assays were conducted in Zoucheng, Shandong province, during the 2023-2024 period. Seven novel multi-component formulations of flowable concentrate for seed treatment (FS) were selected for pre-sowing treatment, while prothioconazole·tebuconazole 40% SC was applied at regreening stage to assess their efficacy against Fusarium crown rot in wheat. Field assay results indicated that sedaxane·fludioxonil·thiamethoxam 27.2% FS had minimal impact on wheat seedling growth and demonstrated strong disease control effect at the seedling stage. When combined with the fungicide treatment at regreening stage, this formulation exhibited the highest disease control efficacy (80.89%) and a significant yield increase of 15.53%. The second effective treatment was metalaxyl·tebuconazole·azoxystrobin 10% FS, with disease control efficacy of 77.07% and yield increase of 13.94%. These findings suggest that combining seed treatment with fungicide application at the regreening stage is an effective strategy for managing Fusarium crown rot in wheat. This study offers new insights into disease management and provides practical guidance for controlling Fusarium crown rot in the region. |
