Pesticide composition for preventing and treating wheat basal stem rot

The invention belongs to the technical field of pesticides, and particularly relates to a pesticide composition for preventing and treating wheat stem rot. The invention relates to a pesticide composition for preventing and treating wheat stem rot. The effective components of the pesticide composition are prepared by binary compounding of flutriafol and magnolol or osthole. When flutriafol and magnolol or osthole in the composition are compounded, 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农药组合物。一种防治小麦茎基腐病的农药组合物，所述农药组合物的有效成分由粉唑醇与厚朴酚或蛇床子素二元复配而成。本发明组合物中粉唑醇与厚朴酚或蛇床子素进行复配时，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。
