摘要：

在农业生产中，水稻稻瘟病的防治主要是利用化学药剂，爱苗是一种广谱的内吸性杀菌剂，常用于多种植物病害的防治。此研究利用菌丝生长速率法，测定了黑龙江省不同地区的14个稻瘟病菌菌株对施爱苗的敏感性。结果表明，供试的14个菌株对爱苗剂的敏感性有显著差异，抑制率从35.31%~62.39%不等，不同地区分离到的菌株生长速率存在差异，同一地区的不同菌株生长速率也存在着差异。说明供试菌株对爱苗的敏感性有差异。

Abstract:

Sensitivity detection of rice blast fungi isolates to Armure from different areas of Heilongjiang Province was measured by mycelium growth rate method. The results showed that there existed differention to the pesticide among the strains, inhibitory ratio from 35.31% to 62.39%. The growth speed of different isolates which coming from different area or same area. So much as in the same physiologicalrace all had discrepancy. The research showed that the insecticide resistance to Armure had emerged in part of the isolates.
