【摘要】 采用菌丝生长速率法测定了13个1,8-萘酰亚胺-二硫代氨基甲酸酯衍生物对晚疫病菌（Phytophthora infestans）的室内毒力.结果表明：1,8-萘酰亚胺4-位取代三氮唑二硫代氨基甲酸酯衍生物3a、3b、3c及3d的毒力较强，其EC₅₀值分别为27.06、26.71、16.55μg/mL和29.25μg/mL.选择最优的1,8-萘酰亚胺4-位吗啉取代三氮唑二硫代氨基甲酸酯衍生物3c进行马铃薯叶片防效检测，通过离体叶片接种鉴定，发现施用3c衍生物可以有效抑制晚疫病菌侵染.更多还原

【Abstract】 The toxicity of 13 types of novel 1,8-naphthalimide derivatives on Phytophthora infestans were determined by mycelial growth rate method.Results showed that 3 a, 3 b, 3 c and 3 d had higher toxicity on Phytophthora infestans,with the EC₅₀ values of 27.06,26.71,16.55 μg/mL and 29.25 μg/mL,respectively.And the best of them（3 c） was selected for further control efficiency on potato leaves.Finally, we proved that 3 c had inhibitory effect on late blight using inoculation on leaves in vitro.更多还原
