| 摘 要： | 采用生长速率法，对18种杀菌剂及药剂配比进行室内毒力测定，结果表明，杀菌剂苯醚甲环唑、嘧菌酯、腐霉利和异菌脲对马铃薯早疫病菌抑制效果好，有效中浓度（EC50）小于1 μg/mL；代森锰锌与嘧菌酯混配，配比为 4∶6、5∶5、6∶4、7∶3、8∶2、9∶1 均有增效作用，其中配比9∶1 增效作用最好，其次是配比6∶4。 |
| 关 键 词： | 马铃薯 早疫病菌 杀菌剂 生长速率法 混配 |

| Abstract: | The mycelial linear growth rate method was used to determine the toxicity of 18 fungicides to Alternaria solani causing the potato early Blight and their proportions in the laboratory. The results showed that the median effective concentration (EC50) of difenoconazole, azoxystrobin, procymidone and iprodione were less than 1 μg/mL, and the inhibitive effects of the above mentioned fungicides were stronger than the other fungicides. Mixing azoxystrobin and mancozeb at volume ratios of 4∶6, 5∶5, 6∶4, 7∶3, 8∶2 and 9∶1 obviously exhibited synergistic effects. The best proportioning was 9∶1, followed by 6∶4. |
