吡唑醚菌酯与氰烯菌酯混用对3种病原菌的抑制效果

Inhibitory Effects of Pyrazolstroxide and Cyenstroxide on 3 Pathogens

    摘要
  • 摘要: 用Wadley法评价吡唑醚菌酯和氰烯菌酯混配对3种重要的植物真菌病原菌厚垣镰刀菌、烟草疫霉菌和立枯丝核菌的抑制效果。结果表明：2种药剂混用对3种病原菌的抑制均无拮抗作用，混配对厚垣镰刀菌和烟草疫霉菌的抑制效果表现出相同的规律，除吡唑醚菌酯和氰烯菌酯为3∶1表现为加成外，其他配比从2∶1到1∶3都表现为增效作用，且增效程度与氰烯菌酯比例增大成正相关；对立枯丝核菌，除吡唑醚菌酯：氰烯菌酯3∶1配比表现为加成外，其他配比均为增效，其中2∶1配比增效最为显著。

     

    Abstract: In this study, the inhibitory effect of the mixture of Pyraclostrobin and Phenamacril on 3 important plant fungal pathogens, Fusarium chlamydosporum, Phytophthora nicotianae and Rhizoctonia solani were evaluated by the Wadley method. The results showed that the mixture of 2 agents had no antagonistic effect on the 3 pathogens. The mixture inhibitory effect on F. chlamydosporum and P. nicotianae showed the same trend that except for the addition of 3∶1 ratio of Pyraclostrobin and Phenamacril, other ratios from 2∶1 to 1∶3 all showed synergistic effect, and the synergistic degree was positively correlated with the increase of Phenamacril ratio. For R. solani, excetp for the ratio of 3∶1 of pyrazolstroxide to Phenamacril, the mixture effect of the other ratios was synergistic, among which 2∶1 ratio was the most significant synergistic.
