| 摘要: |
| 采用孢子萌发法和生长速率法分别测定了多菌灵与代森锰锌混配对梨黑星病菌和苹果斑点落叶病菌的增效作用。结果表明,5种不同比例的多菌灵与代森锰锌混配制剂对2种病原菌均具有显著增效作用，多菌灵∶代森锰锌为1∶1～1∶4的混配组合均表现出协同增效作用，SR值均>1.5，仅1∶5的混配组合SR值<1.5，表现为相加作用。研究结果初步还表明，病原菌抗药性水平愈高，混剂增效比率值越大，增效作用越显著。从降低产品的生产成本和克服病菌的抗药性方面考虑，应以1∶1～1∶3的配比组合较为合理。 |

| Abstract: |
| The synergism of carbendazim and mancozeb against Alternation mail Roberts and Venturia nashicola was tested.The result showed that all the 5 different ratios of carbendazim to mancozeb had obviously synergistic or additional effect.The ratios from 1∶1 to 1∶3 were more advisable considering the reducing of the cost and the overcoming of the resistance. |
| Key words: carbendazim mancozeb Alternation mali Roberts Venturia nashicola mixture formula synergism |
