摘　　要：小麦赤霉病和小麦白粉病是小麦生产中的重要病害,本研究通过田间试验明确了不同药剂对小麦赤霉病和白粉病的综合控制效果.试验结果表明,试验药剂对小麦赤霉病的防治效果较好,病穗防效和相对防效均达90%以上,其中氟唑菌酰羟胺防治效果最佳,病穗防效在94%以上,相对防效在93%以上.小麦白粉病于发病初期用药,防控效果最佳,大发生年份若发病初期用药仍不能控制其扩展,可在扬花初期使用40%环丙唑醇结合小麦赤霉病一并防控.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.
