摘要
单嘧磺酯是新型超高效磺酰脲类除草剂,为了寻找生物活性与之相当、环境友好的同类药剂,室温条件下用单嘧磺酯与氢氧化钠在水中反应合成了单嘧磺酯钠盐,其结构经核磁共振氢谱、红外、质谱及元素分析确认。室内生物测定结果显示,单嘧磺酯钠盐与其母体单嘧磺酯对马唐Digitaria ciliaris、稗草Echinochloa crusgalli、苋菜Amaranthus retroflexus和藜Chenopodium aldum的除草活性基本相当。
Monosulfuron-ester is a patented novel sulfonylurea herbicide with ultra-low dosage of application. In order to improve its environmental property, sodium monosulfuron-ester was synthesized by reaction of monosulfuron-ester and sodium hydroxide in water at room temperature; the structure was comf＇n＇med by 1H NMR, IR, MS and elemental analysis. Its herbicidal activity was compared with monosulfuron-ester by greenhouse bioassay using Digitaria ciliaris, Echinochloa crusgalli, Amaranthus retroflexus and Chenopodium aldum which indicated that the two compounds have the same level of herbicidal activity.
