摘要
在江苏宜兴、安徽凤台、河南内乡、陕西岐山等4地开展了10%叶菌唑悬浮剂防治小麦重要病害赤霉病、条锈病、白粉病的田间试验。结果表明,在小麦抽穗至扬花期喷施2次,10%叶菌唑悬浮剂在600 mL/hm2的用量下,对小麦条锈病有优异的防治效果;在750 mL/hm2的用量下,对小麦赤霉病、白粉病有优良的防治效果,能很好地控制住以上重要病害对小麦的危害。产量测量结果表明,10%叶菌唑在750 mL/hm2的用量下,相对于空白对照,其保产增产率达20%以上。
Field trials were conducted in Jiangsu Yixing,Anhui Fengtai,Henan Neixiang and Shaanxi Qishan to control fusarium head blight(SCAB),stripe rust and powdery mildew.The results showed that the application of 10%metconazole SC at the dosage of 600 mL/hm2 had excellent control effect on wheat stripe rust,and the application of 10%metconazole SC at the dosage of 750 mL/hm2 had good control effect on wheat scab and powdery mildew,and the damage of the above important diseases to wheat was well controlled.The yield measurement showed that the yield of 10%metconazole at the dosage of 750 mL/hm2 was higher than 20%compared with the blank control.
