    摘要: N-(Alkoxy-phosphinyloxy)- and N-(alkoxy-phosphinothioyloxy)-Nalkyl-N''-substituted ureas of the formula

    In this formula: R1 represents methyl or ethyl, R2 and R3 each independently represent a lower alkoxy or dialkylamino radical, X represents a lower alkyl, alkoxy, alkylthio or halogenoalkyl radical, halogen or the cyano group, Y represents oxygen or sulfur, and N REPRESENTS A NUMBER FROM 0 TO 3, WHICH ARE USEFUL AS HERBICIDES IN A METHOD FOR CONTROLLING WEEDS AND WILD GRASSES ARE DESCRIBED. Compositions containing such compounds are also described.
