中文摘要：

研究了HNPC—A14401菌丝浓度抑菌活性及其对孢子萌发的影响，以及其对琥珀酸脱氢酶抑制活性．初步探究了HNPC—A14401的杀菌作用方式和机制。HNPC—A14401对病原菌菌丝扩展以及孢子萌发有较强抑制作用，对琥珀酸脱氢酶抑制活性影响不明显。与啶酰菌胺相比较，HNPC—A14401具有不同的作用位点。

英文摘要：

The fungicidal mode of action and mechanism of the fungicide HNPC-A14401 were studied by research on its in vitro fungicidal activity, its effects on spore germination, and its inhibitory activity against succinate dehydrogenase. HNPC-A14401 had a strong inhibitory effect on mycelial growth and spore germination, but had no significant effect on succinate dehydrogenase inhibition. Compared with boscalid, HNPC-A14401 had different sites of action.
