Novel herbicides and plant growth regulants of the formula <IMG> (I) in which R1 represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenjl, halogenoalkinyl, alkoxyalkyl, alkoxy, cycloalkylalkyl or cycloalkyl, or represents in each case optionally substituted aralkyl or aryl, R2 represents a radical <IMG>, or represents a radical -S(O)n-R7, R3 and R4 independently of one another each represent hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, cyanoalkyl, hydroxyalkyl, alkoxyalkyl, alkylaminoalkyl, alkoxycarbonylalkyl or alkoxycarbonylalkenyl, or represent in each case optionally substituted cycloalkyl, cycloalkylalkyl, cycloalkenyl or cycloalkenylalkyl, or represent optionally substituted heterocyclylalkyl, or represent in each case optionally substituted aralkyl, aroyl or aryl, or represent alkoxy, alkenyloxy, alkinyloxy, aralkyloxy or aryloxy, or, together with the nitrogen atom to which they are bonded, represent an optionally substituted heterocyclic radical, X represents oxygen or sulphur and Y represents oxygen or sulphur, wherein R5 and R6 independently of one another each represent alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, alkoxyalkyl, alkoxy, cycloalkyl or cycloalkylalkyl, or represent in each case optionally substituted aryl, aralkyl or heteroaryl, or, together with the nitrogen atom to which they are bonded, represent an optionally substituted heterocyclic radical, R7 represents alkyl, alkenyl, alkinyl, cycloalkyl or cycloalkylalkyl, or represents in each case optionally substituted aralkyl or aryl and n represents the number 0, 1 or 2, but wherein R2 only represents a radical -S(O)n-R7 if R3 and R4 do not simultaneously represent methyl. Intermediates therefor where NR3R4 is replaced by Cl are also new.
