The invention relates to N-heterocyclyl substituted thienyloxy-pyrimidines of formula (I), agriculturally useful salts thereof, methods and intermediates for their production as well as the use of these compounds or agents containing them in the control of undesirable plants. In said formula, the variables have the following meanings: W, X, Y, Z represent, independently of each other, N or CR3, where at least one of said variables is CR3; R1 represents hydrogen, halogen, cyano, alkyl, halogenoalkyl, alkoxy or halogenoalkoxy; R2 represents hydrogen, halogen, cyano, alkyl, alkenyl, alkynyl, halogenoalkyl, halogenoalkenyl, halogenoalkynyl, alkoxy, alkenyloxy, alkynyloxy, halogenoalkoxy, alkoxyalkyl, alkylamino, dialkylamino, alkylthio, halogenoalkylthio, alkylsulfinyl, halogenoalkylsulfinyl, alkylsulfonyl, halogenoalkylsulfonyl, COOR7 or CONR8R9; R3 represents hydrogen, halogen, cyano, nitro, alkyl, halogenoalkyl, alkoxy, halogenoalkoxy, alkylthio or halogenoalkylthio, alkylsulfonyl or COOR?7; R4, R5, R6¿ represent hydrogen, halogen, cyano, alkyl, halogenoalkyl, alkoxy, halogenoalkoxy, alkylthio, halogenoalkylthio, alkylsulfonyl or halogenoalkylsulfonyl; R7 represents hydrogen, alkyl, alkenyl, alkynyl or halogenoalkyl; R8 represents hydrogen, alkyl, alkenyl, alkynyl or alkoxy and R9 represents hydrogen, alkyl, alkenyl or alkynyl. |
