摘　　要：该试验以葡萄霜霉病为研究对象,通过喷施不同剂量的复配药剂37%氟吡菌胺·烯酰吗啉和32%氟吡菌胺·吡唑醚菌酯,调查并分析其对葡萄霜霉病的防治效果。试验结果表明,32%氟吡菌胺·吡唑醚菌酯750倍、1000倍液对葡萄霜霉病的防效分别为87.70%、81.99%,而药剂37%氟吡菌胺·烯酰吗啉750倍、1000倍、1500倍和药剂32%氟吡菌胺·吡唑醚菌酯1500倍液对葡萄霜霉病的防效表现一般。The study was conducted to investigate and analyze the efficacy of two fungicide combination,37%fluopicolide-dimethomorph and 32%fluopicolide-pyraclostrobin,in preventing and controlling grapevine downy mildew through the application of varying doses.The experimental results indicated that the preventive effect of 32%fluopicolide-pyraclostrobin 750 fold liquid on grape mildew was 87.70%,while the effect for 1000 fold liquid was recorded at 81.99%.In contrast,the preventive effects observed with the agents comprising 37%fluopicolide-dimethomorph at concentrations of 750 fold liquid,1000 fold liquid,1500 fold liquid and the agent containing 32%fluopicolide-pyraclostrobin 1500 fold liquid were found to be average.
