Bactericidal composition for preventing and treating wheat basal stem rot

The invention belongs to the technical field of pesticides, and particularly relates to a bactericidal composition for preventing and treating wheat stem rot. The invention discloses a bactericidal composition for preventing and treating wheat stem rot. The bactericidal composition is prepared by binary compounding of flutriafol, carvacrol, eugenol or aloe-emodin as an active ingredient. When flutriafol in the composition is compounded with carvacrol, eugenol or aloe-emodin, the co-toxicity coefficient of fusarium pseudograminearum causing the wheat stem rot is larger than 120, a synergistic interaction effect is shown, the prevention and treatment effect on the wheat stem rot can be improved, and a support can be provided for developing a novel agent for preventing and treating the wheat stem rot. 本发明属于农药技术领域，具体涉及一种防治小麦茎基腐病的杀菌组合物。一种防治小麦茎基腐病的杀菌组合物，所述杀菌组合物的有效成分由粉唑醇与香芹酚、丁香酚或芦荟大黄素二元复配而成。本发明组合物中粉唑醇与香芹酚、丁香酚或芦荟大黄素进行复配时，对引起小麦茎基腐病的假禾谷镰刀菌的共毒系数大于120，表现为协同增效作用，可以提高对小麦茎基腐病的防治效果，可以为开发防治小麦茎基腐病的新型药剂提供支持。
