摘　　要：从不同地方采集分离了57个稻瘟病菌菌株,并在离体条件下测定了这些菌株对烯肟菌胺(SYP-1620)的敏感性。结果表明:这些菌株均未对烯肟菌胺产生抗性,其中最敏感的菌株EC50值为0.03028mg/L,最不敏感的菌株EC50值为0.18297mg/L,所有菌株敏感性频率分布近似正态分布,初步确定将所有菌株的EC50平均值0.09168mg/L作为稻瘟病菌对烯肟菌胺的敏感基线。Fifty seven Magnaporthe grisea strains were sampled from different aeras,and their sensitivities were examined to SYP-1620 in vitro. The results showed that these strains had no resistant to SYP-1620. The EC50 of the most sensitive strain was 0.030 28 mg/L and the EC50 of the least sensitive one was 0.182 97 mg/L,the sensitivity frequencies distribution of the strains was similar with Gaussian distribution,The average EC50 0.091 68 mg/L was the baseline-sensitivity of Magnaporthe grisea to SYP-1620.
