摘要：

为解决葡萄霜霉病对常规防治药剂抗药性问题,采用田间预防和治疗试验,测定氟醚菌酰胺、氰霜唑、氟噻唑吡乙酮、氟醚菌酰胺+氰霜唑、氟醚菌酰胺+氟噻唑吡乙酮对葡萄霜霉病的防治效果。试验结果表明,3种杀菌剂及组合对葡萄霜霉病有一定的防治效果,其保护效果要好于治疗效果,3种杀菌剂及组合,3次药后7天对葡萄霜霉病的病叶防效为87.23%~100%,病指防效96.47%~100%;3次药后14天各处理对葡萄霜霉病的病叶防效54.39%~89.66%,病指防效78.40%~97.33%。3种杀菌剂及组合,3次药后7天治疗效果以50%氟醚菌酰胺WDG 7500倍+10%氟噻唑吡乙酮OD 5000倍最好,病叶防效与病指防效分别为75.17%和81.77%;3次药后14天治疗效果以100 g/L氰霜唑SC 2500倍防效相对最高,病叶防效和病指防效分别为64.30%和73.42%。综合田间预防和治疗试验效果,确定50%氟醚菌酰胺WDG 7500倍+10%氟噻唑吡乙酮OD 5000倍可在生产中推广应用。

Abstract:

The paper aims to solve the resistance of grape downy mildew to conventional fungicides. The control effects of fluopimomide, cyazofamid, oxathiapiprolin, fluopimomide + cyazofamid and fluopimomide + oxathiapiprolin on grape downy mildew were tested using the field inhibition and control methods. The results showed that the three fungicides and their combinations had certain effects on grape downy mildew, the protective effect of them was higher than the curative effect, seven days after 3 times’ application, the disease leaf prevention rate of the three fungicides and their combinations was 87.23%-100%, the disease index prevention effect was 96.47%-100%; and fourteen days after 3 times’ application, the disease leaf prevention rate was 54.39%-89.66%, and the disease index prevention effect was 78.40%-97.33%. Among the three fungicides and their combinations, fluopimomide (50%, WDG diluted by 7500 times)+ oxathiapiprolin (10%, OD diluted by 5000 times) showed the best control effect seven days after 3 times’ application, the disease leaf prevention rate and disease index prevention effect was 75.17% and 81.77% respectively; cyazofamid (100 g/L, SC diluted by 2500 times) showed the best control effect fourteen days after 3 times’ application, the disease leaf prevention rate and disease index prevention effect was 64.30% and 73.42%, respectively. According to the protective effect and the curative effect in field, we suggest that fluopimomide (50%, WDG diluted by 7500 times)+ oxathiapiprolin (10%, OD diluted by 5000 times) should be recommended as a fungicide applied on grape downy mildew.
