Novel hydantoin derivative which is represented by the formula: ##STR1## (wherein X and Y represent a halogen atom, R.sup.1 represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group or an alkynyl group, R.sup.2 represents a hydrogen atom, an alkyl group, an alkenyl group or an alkynyl group, and R.sup.3 and R.sup.4 independently represent a hydrogen atom or a lower alkyl group), and a herbicide containing said derivative as effective ingredient. This hydantoin derivative exhibit excellent weed-killing activity for harmful weeds and low phytotoxicity for crop plants.
该专利涉及一种新型的氢嘧啶衍生物,其化学式为:##STR1## (其中X和Y代表卤素原子,R.sup.1代表氢原子、烷基、环烷基、烯基或炔基,R.sup.2代表氢原子、烷基、烯基或炔基,R.sup.3和R.sup.4独立地代表氢原子或低碳烷基),以及一种以该衍生物为有效成分的除草剂。该氢嘧啶衍生物对有害杂草具有良好的除草活性,对作物植物的毒性较低。
