药剂拌种、喷雾对小麦黄花叶病的防治效果研究

Study on Effect of Chemical Seed Dressing and Spray Against Wheat Yellow Mosaic Disease

根据小麦黄花叶病防控项目要求和生产需求,我们选择了0.135%赤·吲·芸苔可湿性粉剂(碧护)、中量元素水溶肥料(沃生)、30%噁霉灵等3种药剂对小麦黄花叶病发病田进行药剂拌种防治试验,选择了0.135%赤·吲·芸苔可湿性粉剂、中量元素水溶肥料、30%噁霉灵、8%宁南霉素、5%氨基寡糖素等5种药剂对小麦黄花叶病发病田进行药剂喷雾防治试验,结果表明,0.135%赤·吲·芸苔可湿性粉剂拌种防治效果较好,为45.40%,增产效果为20.90%;0.135%赤·吲·芸苔可湿性粉剂和5%氨基寡糖素喷雾防治效果较好,分别为64.66%和61.19%,增产效果分别为13.41%和12.91%,这2种防治方法和药剂在生产中可作为综合防治措施用于病区防治。

According to the requirements of wheat yellow mosaic disease prevention and control project,We chose VitaCat,Wuxal,Hymexazol for wheat seed dressing,and chose VitaCat,Wuxal,Hymexazol,Ningnanmycin,Amino Oligosaccharins for spray prevention and treatment.The results indicated that VitaCat showed better in wheat seed dressing,and the control effect was 45.40%.In the spray prevention and treatment test,the control effects of VitaCat and Amino Oligosaccharins were 64.66% and 61.19% respectively.Therefore,VitaCat(seed dressing or spray)and Amino Oligosaccharins(spray)can be used in integrated control.
