A 1-phenyl, naphthyl or aralkyl-4-(N,N-di-substituted carbamoyl)-1,2,4-triazol-5-one derivative represented by the general formula (I) ##STR1## wherein A is an unsubstituted or substituted phenyl group, 1-naphthyl group, 5,6,7,8-tetrahydro-1-naphthyl group or an aralkyl group such as an unsubstituted or substituted benzyl group and so on, R.sub.1 is a lower alkyl group and so on, and R.sub.2 is an unsubstituted or substituted phenyl group and so on, was prepared as novel compounds. This 1-substituted-4-carbamoyl-1,2,4-triazol-5-one derivative does not substantially exhibit phytotoxicity to various agricultural crop plants and therefore is useful as a selective herbicide.
通用公式(I)表示的一种1-苯基、萘基或烷基-4-(N,N-二取代氨基甲酰基)-1,2,4-三唑-5-酮衍生物,其中A是未取代或取代的苯基、1-萘基、5,6,7,8-四氢-1-萘基或烷基基团,如未取代或取代的苄基基团等,R.sub.1是低碳基基团等,R.sub.2是未取代或取代的苯基基团等,作为新型化合物制备。这种1-取代-4-氨基甲酰基-1,2,4-三唑-5-酮衍生物对各种农业作物基本不具有植物毒性,因此可用作选择性除草剂。
