Abstract: Wheat scab and wheat powdery mildew are important diseases in wheat production. This study determined the comprehensive control effects of different fungicides on wheat scab and wheat powdery mildew through field trials. The experimental results showed that the control effect of the experimental agents on wheat scab was good, with over 90% of disease ear control effect and relative control effect. Among them, fluconazole acyl hydroxylamine had the best control effect, with over 94% of disease ear control effect and over 93% of relative control effect. Wheat powdery mildew was the best prevented and controlled by using chemicals at the initial stage of the disease. If the spread of wheat powdery mildew cannot be controlled by chemicals at the early stage of the disease in the high incidence year, 40% cyclopropazole can be used in combination with prevention and control of wheat scab at the early stage of flowering.
