It induces crop＇s yield loss and quality drop. Chemical control is a good means to control the disease, such as triadimefon, difenoconazole and flusilazole. [Results] In field trial, SYP-1620-tebuconazole 20% SC had excellent control effect against capsicum powdery mildew. At 100- 200 g a.i./ha, by using the mixed fungicide two or three times through spraying means, the control effect was better than kresoxim-methyl and triadimefon.
