Abstract： Field experiments were conducted in 2O22 and 2O23 using the spring wheat variety Yongliang 15 as the experimental material.Four treatments were applied：no silicon fertilizer （CK），spraying silicon fertilizer at the jointing stage（JS），spraying silicon fertilizer atthebooting stage（BS），and spraying silicon fertilizer five days after anthesis （HS）. The study examined the prevention and control of wheat powdery mildew and its impacton grain quality under field conditions.The results indicated that spraying silicon fertilizer during the jointing andboting stages had an inhibitory effct on the occurrence of wheat powdery mildew，with the jointing stage showing the most effective results. Spraying silicon fertilizer during these stages significantly increased wheat yield.Spraying silicon fertilizer at the jointing stage enhanced wheat proteinand starch content，thereby improving grain quality.In conclusion，under the conditions of this experiment，spraying silicon fertilizer during the jointing stage has the greatest effect in reducing the occurrence of powdery mildew while improving wheat yield and quality.
