An N-(2,3-epoxypropylene)-N-aralkylsulfonamide of formula (I): ##STR1## wherein R.sup.1 is an alkyl group, a haloalkyl group, an aralkyl group or an aryl group which may be substituted, R.sup.2 and R.sup.3, independently of each other, are a hydrogen atom or an alkyl group, R.sup.4 and R.sup.4', independently of each other, are a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom, R.sup.5, R.sup.6 and R.sup.7, independently of each other, are a hydrogen atom, an alkyl group, a haloalkyl group or an aryl group, and n is 0 or 1. The novel compounds have excellent herbicidal effect based on the physiological selectivity between rice plant and weeds, and have low phytotoxicity against rice plant.
公式(I)中的N-(2,3-环氧丙烷基)-N-烷基磺酰胺:##STR1##其中R.sup.1是烷基,卤代烷基,芳基烷基或取代的芳基;R.sup.2和R.sup.3独立地是氢原子或烷基;R.sup.4和R.sup.4'独立地是氢原子,烷基,烷氧基或卤素原子;R.sup.5,R.sup.6和R.sup.7独立地是氢原子,烷基,卤代烷基或芳基;n为0或1。这些新化合物基于水稻植物和杂草之间的生理选择性具有出色的除草效果,并且对水稻植物的植物毒性较低。
