摘要
【目的】测定葡萄霜霉病菌对4种药剂烯酰吗啉、嘧菌酯、甲霜灵、乙蒜素的敏感性,旨在为合理施药及对该病的抗药性监测提供科学依据。【方法】采用叶盘保湿法测定来自新疆不同地区和单位的11个葡萄霜霉病代表性菌株对烯酰吗啉、嘧菌酯、甲霜灵、乙蒜素的敏感性。【结果】葡萄霜霉病菌对烯酰吗啉、嘧菌酯、甲霜灵和乙蒜素的敏感基线分别为0.197 1、0.167 9、0.936 7和0.575 1μg/mL。【结论】目前烯酰吗啉、嘧菌酯可以作为新疆葡萄生产中霜霉病发生期的主要治疗剂,但不要连续使用。
[ Objective ] The purpose of this study aims to research the sensitivity of Plasmopara viticola to 4 fungicides： dimethomorph, azoxystrobin, metalaxyl and ethylicin in order to provide scientific basis for chemical control of Plasmopara viticola and monitor the resistance of grape downy mildew in Xinjiang region. [ Method ] The sensitivity of the above four fungicides collected from different areas in Xinjiang to Plasmopara viticola （grape downy mildew） was assayed by using leaf discs method. [ Results] The results showed the sensitive baseline of grape downy mildew to dimethomorph, azoxystrobin, metalaxyl and ethylicin were 0. 197 1,0. 167 9, 0. 936 7 and 0. 575 1 μg./mL. [ Conclusion ] The results have proved that dimethomorph, azoxystrobin can be used as the chemical therapeutical agent for Plasmopara viticola, but could not be used consecutively.
