【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、1 000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、1 000倍、1 500倍和药剂32%氟吡菌胺·吡唑醚菌酯1 500倍液对葡萄霜霉病的防效表现一般。更多还原

【Abstract】 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 1 000 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, 1 000 fold liquid, 1 500 fold liquid and the agent containing 32% fluopicolide-pyraclostrobin 1500 fold liquid were found to be average.更多还原
